| Groove Base ØD | ≤1.5 μm | ≤10 μm |
| Groove Flanks B | ≤0.3 μm | ≤4 μm |
Note: It is recommended to have 50% to 90% of the working surface material contact area value
INSTALLATION
SPN-2 chevron seal is 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.
