INSTALLATION K152 and K153 chevron seals are used in open housing. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil. NOTES Due to the special formulated reinforced cotton fabric with nitrile rubber service life is much longer than the normal cotton fabric seals.
