KB20W

KB20W is a low-friction piston seal which provides a reduced frictional footprint under operation thanks to its small contact sealing bulb. The sealing face is supported by two tapered back-up rings which help prevent seal extrusion damage, rolling and spiral failure while under system pressure.

The low contact footprint of the sealing element provides good leakage control while offering a seal that is capable of increased operating speeds when compared to our standard KB20 profile. Like its sister seal the KB20W has the ability to operate at both high and low temperatures and in a multitude of different media through the correct choice of material combination.
