PTFE Back-up Rings
Back-up rings are the most common anti-extrusion devices in dynamic
sealing. They provide simple solutions to safely increase system
function by positioning a more robust material adjacent to the
extrusion gap,taking the seal’s place and providing a barrier
against high pressures. Back –ups can be used to offset the reduced
pressure rating effects of wear rings or to improve seal against
pressure spikes,or to ensure seal performance at higher
tempertures.
PTFE Seal Ring
PTFE Rings are an ideal solution for sealing applications where
there are high temperatures and corrosive liquids or gases
involved.
Application :
• Mechanical Seal
• Chemical environments
• Use in acidic or basic environments
• Sealing of moving or sliding surfaces

Main material and properties
| 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. |
