Washer Hoses, repairing
General information
A concept has been developed to facilitate the repair of
washer hoses.
Various individual hose connectors, adaptors, Ethylene
Propylene Diene Methylene (EPDM) rubber hoses and
shrink tubing will be offered as replacement parts.

Repair parts will be available for both smooth and
corrugated hoses.
Smooth hoses, repairing
Smooth hoses with a diameter of 5 x 1 mm or 6 x 1 mm
can be repaired with a EPDM repair hose section.
- Trim and remove damaged sections of hose.
- Choose matching EPDM repair hose - 2 - and cable ties
from Parts Catalog.
- Insert hose - 1 - and - 3 - into ends of EPDM repair
hose - 2 - to a depth of at least 10 mm - arrows - .
Washer Hoses, repairing
- Secure cable ties - 1 - as illustrated.
Corrugated hoses, repairing

Note:
„
Area to be repaired must but be under stress of
stretching or bending.

If damaged area is longer than 20 mm, a new
section of corrugated hose must be obtained, and
two sets of adapters inserted using following the
following procedure.
- Trim and remove damaged sections of hose.
