Lip Seal O Ring

O ring and lip seals o rings and lip seals are primary seal devices as well as secondary sealing components for magnetic and spring loaded mechanical seals.

Lip seal o ring.

Lip seal made from urethane for flexibility and resistance to impact abrasion and hydrocarbons o ring made of buna nitrile also called buna n for use with a variety of fluids from petroleum to aliphatic hydrocarbons functions in temperatures from 40 to 200 degrees f and has a durometer of 92a specifications for this item. Also known as loaded lip seals and polypaks an o ring secures these u cups to the rod or piston for better sealing performance at lower pressures than unsupported u cup seals. High stability o ring loaded u cup seals. An o ring is a solid rubber seal shaped like a dough nut or torus.

The o ring piston seal was designed to alleviate the relaxing lip seals but the reduced piston to wall clearance inherent with the o ring design when installed in a floating piston caliper eliminates what duntov said was necessary. O rings and lip seals are provided in a variety of application specific designs sizes and elastomeric materials which are determined based on compatibility of media being sealed temperature and pressure. When compressed between mating surfaces an o ring blocks the passage of liquids or gases.

Because u cups have a sealing lip on both the inside and outside edges they can be used for rod and piston sealing. Metric shaft double lip seal are used for keeping dirt dust water or other particles out while retaining lubricant in rotary shaft equipment. Also known as loaded lip seals and polypaks an o ring secures these u cups to the rod or piston for better sealing performance at lower pressures than unsupported u cup seals. 2012992 01 01 sls seal.
