Lip Seal O Ring

High stability o ring loaded u cup seals.

Lip seal o ring.

Lip seals are used as high pressure seals and in lower pressure applications. 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. Oil seals seal both dynamically on the shaft and statically on the outer diameter of the seal. When compressed between mating surfaces an o ring blocks the passage of liquids or gases.

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. 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. 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. 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. 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.
