Oil Filter 2605539870 For Screw Air Compressor

    Two things age first. The sealing ring is rubber, and rubber in a hot store, near a window, or beside oily rags loses its resilience and takes a set. An element with a hardened ring will not compress properly no matter how carefully it is tightened, and the leak that follows is usually blamed on the thread rather than on the ring. The medium ages as well: paper-based material takes up moisture from the air, and once damp its fibres lose strength, the pleat peaks soften, and the pressure behaviour changes from what was tested.
