| Advantages |
1.Good abrasion resistance, long lifetime. |
Product Show
| 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. |
