Elastomers and Age Control
Editor
Charles I. Gale
This entire issue of Service News magazine is devoted
to O-rings. It seems ironic that a simple, molded, doughnutshaped part made of a single material could warrant so
much attention. The selection of a specific O-ring is based
on a variety of factors, including fluid media resistance, temperature range, hardness, durability, gland size, static or
dynamic application, etc. There have been some significant
technological advances in materials in recent history, but
sometimes the best solution is still the simplest. While the
use of fluorosilicone and fluorocarbon materials has become
more widespread, the best choice often continues to be a
basic nitrile butadiene (or Buna N) elastomer. Unfortunately,
the nitrile compounds require age control.

Cover: A C-130 based with the 50th TAS at
Little Rock AFB faces a new day at Ramstein AB in Germany. This aircraft is one of
the many Hercules airlifters being used to
support Operation Joint Endeavor, bringing
relief to war-ravaged Bosnia.
J. C. Davis
Why is basic nitrile a better choice than a fluorosilicone
or fluorocarbon compound which doesn’t require age control? The tradeoff for fluorocarbon is higher cost and decreased low-temperature resistance; for fluorosilicone it is high
cost and decreased durability. The cost factor is influenced by raw materials costs, processing costs, shrinkage control, and other considerations.
In the past, MIL-STD-1523, “Age Control of Age-Sensitive Elastomeric Material (for
Aerospace Applications),” has provided the requirements for age control. This included
requirements for elastomeric O-rings as well as other age-sensitive products such as aircraft hoses. The original MIL-STD-1523, issued in 1973, gave specific requirements for
receipt and delivery of age-sensitive materials. Revision (A) to MIL-STD-1523 was
released in 1984. This revision simplified the requirements by controlling only the allowable time period from start to end; that is, cure date to “maximum age at acceptance by a
Government Acquiring Activity.” The contractor was required to control all the interim steps
and requirements so that the overall provisions of the military standard would be satisfied.
Now, as a result of the Perry Initiative to reduce the number of military specifications,
MIL-STD-1523A has been canceled without replacement. Age controls for hose products
are delineated by SAE Aerospace Standard AS1933, “Age Controls for Hose Containing
Age-Sensitive Elastomeric Material.” However, there is no reference to or replacement for
age control of O-rings and other non-hose products. Does this mean that age control of
O-rings is no longer necessary? Emphatically, no. This simply transfers the total responsibility to the contractor.
The transfer of responsibility for age control to the contractors will not affect the ability of Lockheed Martin Aeronautical Systems (LMAS) to control and deliver quality products to our customers. We and other OEMs have had internal requirements documents all
along. These documents follow guidelines of the previous military requirements while tailoring the requirements to individual company needs. The LMAS controlling document is
ER8094, “Limited Calendar Life Limitations.” This document will continue to be used by
LMAS to ensure that our customers receive a fresh and viable product.
Sincerely,
J. C. Davis, Manager

information for the AS3551 O-ring. Fuel system Orings and backup rings are listed on Charts 4A and 4B.
Breathing oxygen system O-rings and backup rings are
listed on Charts 5A and 5B.
A New Format
When using the charts, be sure to refer to the notes
below. This information should be consulted any time
part substitution is considered. If problems concerning
substitutability are encountered, contact your nearest
Lockheed Martin Field Service representative. We have
also provided the names and addresses of several
selected manufacturers of O-rings and backup rings for
your convenience.
ervice News is pleased to present its fourth special
issue devoted entirely to the subject of O-rings.
The present update contains the latest information
on the O-rings (also known as preformed packings) and
backup rings used in the hydraulic, lubrication, fuel,
and breathing oxygen systems of the Hercules airlifter
and many other types of aircraft. This article consists of
a multi-part index and 12 component charts. Please note
that these O-ring charts do not authorize random substitutions, but are provided to Hercules operators for
comparison and informational purposes.
To help simplify use, the index has been reformatted to include an alphanumeric listing of all O-rings and
backup rings, and listings by system and component
type. Superseded parts are clearly identified for each
system and application (gland or boss). Temperature
ranges are now provided in both Fahrenheit and Celsius
scales. Note that the temperature values shown in
parentheses are nominal values provided by Lockheed
Martin Aeronautical Systems Standards and Specifications Engineering.
Chart Notes:
Hydraulic system O-rings and backup rings are listed on Charts 2A, 2B-1, 2B-2, 2B-3, 2C, and 2D. Chart
2A details gland O-rings used in hydraulic systems. An
M83461/1 O-ring listing was added to supplement previously issued information. The 2B-series of gland
backup ring charts have been expanded to three. The
latest addition (2B-3) lists the sizes of MS27595 continuous backup rings. Also, M8791/1 Teflon backup
rings were added to the 2B-1 chart. The contents of
Chart 2C covering boss O-rings and Chart 2D for boss
backup rings have not been changed since the previous
Service News O-ring issue.
Lubrication oil system O-rings and backup rings
are listed on Charts 3A and 3B. Both charts now include
Lockheed Martin SERVICE NEWS V22N4 - V23N1
•
All dimensions are given in inches.
•
In Charts 2A, 3A, and 4A: O-ring sizes
-013 through -028, -117 through -149, and -223
through -247 of MS28775, MS29561, MS29513,
and M83248/1 are intended for use as static seals.
These O-rings should not to be used in applications
involving reciprocating or rotary motion.
•
Charts 1, 2A, 2C, 3A, 3B, 4A, and 4B: O-rings
made of Buna N have a limited shelf life. Any Orings made of this material still in stock with cure
dates exceeding 120 months should be discarded.
•
In Chart 1, the temperatures listed in the
Temperature Range column are nominal values
supplied by Lockheed Martin Standards and
Specifications Engineering.
•
Charts 2A, 3A, and 4A: When an O-ring made of
fluorocarbon material is to be substituted for one
made of Buna N, special care should be taken with
regard to temperature ranges. Fluorocarbon O-rings
may not be adequate if they are used in aircraft

which operate primarily in frigid environments. Orings made of fluorocarbon material are somewhat
less tolerant of low temperatures than those made
of Buna N.

COMMON JET FUELS
Preformed Packings
A GLOSSARY OF USEFUL TERMS
BACKUP RING - A spiral-cut or continuous ring of
Teflon-type material placed in the gland between the
O-ring and groove side walls to prevent seal extrusion.
GLAND O-RING - A preformed packing used to seal
grooved cutouts conforming to MIL-G-5514 or the
equivalent.
O-RING - A torus-shaped preformed packing, made
of synthetic rubber, used to seal fluid connections.
BOSS O-RING - A preformed packing used to seal
fluid connections conforming to MS33649 or equivalent.
PACKING - A generic term used to describe a
hydraulic seal that prevents leakage between two
surfaces.
DYNAMIC SEAL - A type of seal where there is relative motion between some part of the packing and
the sealing surface, such as a piston and shaft seal.
STATIC SEAL - A type of seal where there is no relative motion between the O-ring and sealing surface. In some cases, limited freedom may be provided to permit the packing to change its shape within the gland when under pressure.
EXTRUSION - The distortion or flow, under pressure, of a portion of a seal into the clearance
between mating metal parts.

BOSS O-RINGS for Use in
O-Rings Revisited
One of the most confusing and aggravating jobs faced by most mechanics is the finding, identifying,
removing, and replacing of preformed packings, most often referred to as simply “O-rings.” This issue is for
those mechanics—to assist in cross-referencing part numbers, in determining dimensions, and in proper
care and handling from storage to installation of preformed packings.
So reads the first paragraph of the main article in Service News, Vol. 3, No.1, dated January-March
1976. It was our first special O-ring issue, and it turned out to be the most frequently requested issue the
magazine had published up to that time.
An update, significantly enlarged and revised, was issued in Vol. 11, No. 3, the July-September issue
in 1984. Referring to the original O-ring feature, the introduction to the update comments: The article
proved to be so popular that our supplies of the issue that contained it were soon exhausted. Volume 3,
Number 1 of Service News has been completely out of stock for several years, and we have had to disappoint the many readers who have contacted us and asked for additional copies. With this issue, we hope
again to be able to satisfy the need for a reliable and easy-to-use source of data on O-rings.
The new issue helped meet that need, but not for long. It attracted so much interest that the new issue,
too, was soon out of stock, even though an extra thousand copies had been printed. In the April-June
Service News issue of 1990, (Volume 17, Number 2) we offered another O-ring edition, again fully updated and revised, and this time we printed two thousand extra copies. That proved to be a more realistic number, and since then we have been able to offer copies to our readers who request them. Until now, that is.
Fortunately, when both the need to modernize our published O-ring data and dwindling stocks of the
previous O-ring issue reminded us that the time for yet another revision had arrived, Jim Roberts of our
Engineering Standards and Specifications Group was ready. Jim’s update, which is published in this issue,
represents the largest and most thoroughgoing presentation of O-ring information yet offered in Service
News magazine. We are most grateful for his careful and comprehensive work. This is also the appropriate time to salute the earlier contributions of Ed Akers, Anne Anderson, Jim Buttram, Dan Jolley, and Jim
Loftin, whose dedicated efforts on our previous O-ring issues provided both the models and the tradition of
excellence upon which the present edition could be based.
