1.Good abrasion resistance, long lifetime.
|PTFE Ring||1. Low coefficient of friction, good abrasion.|
|2. Two modified plastic back-up rings to avoid extrusion.|
|3. The initial design in shrink range ensures sealing performance at low pressure.|
|4. The rectangular geometry of seal is stable.|
|Back-up Ring||1. Seals and elastomer are with extruding resistance performance.|
|2. To avoid the elastomer's broken and make it easy to install, oblique incision open in the radial plance.|
|3. Be used as wiper seal, and scrape off the internal pollutants.|
|4. High elastic modulus materials, has high rigidity and extruding resistance performance in high pressure and temperature|
|5. Round angle can avoid breaking the elastomer down.|
|NBR Ring||1. Avoid crimping with T form elastomer.|
|2. Avoid extruding with back-up ring.|
|3. With initial pre-tightening force, it has good sealing performance in low and high pressure.|
|4. Its geometry shape makes it stable and with good leakage ability.|
|5. Easy to install and decrease leakage.|
|6. Chamfer of elastomer can save much space, and reduces the load of back-up ring.|
|(Depend on material of O-ring)|
