HDPE Flange Coupling
Installation / Assembly
Instructions
1.
The following instructions apply to the Grinnell Figure 9094
HDPE Flange Couplings. These couplings are designed to
join high-density polyethylene (HDPE) to ANSI class 125 or
150 flanged piping systems. The HDPE pipe is to conform
to ASTM D2447, D3000, D3035, or F714 (metric sizes to
ISO 161/1, DIN8074, and AS8074), at ambient temperatures
with wall thickness from SDR 7.3 to 32.5. The Figure 9094
couplings are not intended for use on anything other than
HDPE. Refer to data sheet G584 for more information.

Place the flange housings over
HDPE pipe. The flange must be assembled with its machined teeth on
the HDPE pipe. The gasket cavity
must face the pipe end. Fasten the
draw bolts and nuts loosely.

Never remove any piping component nor correct or modify any piping deficiencies without first de-pressurizing and
draining the system. Failure to do so may result in serious
personal injury, property damage, and/or impaired device
performance.
It is the Designer’s responsibility to select products suitable
for the intended service and to ensure that pressure ratings and performance data are not exceeded. Material and
gasket selection should be verified to be compatible for the
specific application. Always read and understand the installation instructions.
The products described herein must be installed and maintained in compliance with this document, in addition to the
standards of any other authorities having jurisdiction. Failure
to do so may result in serious personal injury or impair the
performance of these devices.
The owner is responsible for maintaining their mechanical
system and devices in proper operating condition. The installing contractor or device manufacturer should be contacted with any questions.
Exercise care when connecting HDPE piping to a steel-pipe
system when hydrocarbons (for example, cutting oils) are
present. Refer to the HDPE piping manufacturers’ installation instruction for guidance, which may recommend flushing the steel-pipe system prior to connection.
To avoid injuries from sharp machined gripping teeth, wear protective gloves when handling couplings.
3. FLUSH FACE
The HDPE pipe end must be flush
with the flange face. Use a ruler or
straight edge to verify.
! WARNING
Page 1 of 2
1. SQUARE CUT HDPE PIPE
HDPE pipe must be cut square.
The maximum allowed tolerances are .125 inch (3.2 mm) on HDPE
pipe sizes 2 inch to 4 inch and .156
inch (4.0 mm) on 6 inch and larger
sizes. Make sure that the pipe end,
within 1 inch from the end, is clean
and free from indentations, projections, scratches, or other harmful surface defects such as scale,
chips, and grease.

4. TIGHTEN DRAW BOLTS
Tighten the draw bolts and nuts
alternately and equally until the
housing bolt pads meet forming
metal-to-metal contact. Tighten by
another 1/4 to 1/2 turn to ensure
the nuts and bolts are tight and
secure.
5. CHECK GASKET AND
LUBRICATE
Cover the sealing edges and outer surfaces of the gasket with a
fine layer of lubricant. Use a petroleum-free silicone-based lubricant
such as Dow Corning® 7 Release
Compound.
! CAUTION
To avoid injuries from sharp machined gripping teeth, wear protective gloves when handling
couplings.

To prevent degradation of the polymer, do not use hydrocarbonbased oils, grease, or soap-based
solutions.

6. INSTALL GASKET
Mount the gasket into the cavity
between the pipe OD and flange
recess. Make sure that the bottom
of the gasket (the marking side) is
positioned and seated against the
bottom of the flange recess.
7. MATE ADJOINING FLANGE
Bring the adjoining flange face to
face with the Figure 9094 flange.

9. TIGHTEN NUTS
Tighten all nuts evenly as with a
regular flange assembly, until faces contact firmly. Apply the recommended flange joint torque evenly to all the bolts. Mating Bolts and
Nuts are not supplied.
Flange mating bolts must be at
least SAE J429 Grade 5 or stronger. It is the responsibility of
the purchaser to verify correct
length for the intended application. See Table 1 for mating bolt
recommendations.
8. ADD BOLTS
Add flange bolts and hand-tighten
nuts. All the bolts shall be inserted from the same direction. Make
sure that the oval neck of the bolt
engages into the bolt hole of the
housing.
