4. FAQ
Q: Why is filled PTFE chosen for this piston seal ring?
A: Filled PTFE offers low friction, excellent wear resistance, and dimensional stability under high pressure. It maintains its shape through repeated cycles, ensuring consistent sealing performance and long service life. It also resists most hydraulic fluids and operates reliably across a wide temperature range.
Q: How do I install this split piston seal ring correctly?
A: Gently expand the ring by hand (do not overstretch it) and carefully seat it into the piston groove. If installing multiple rings, stagger their split gaps by 120° to prevent fluid bypass. When inserting the piston into the cylinder, use a tapered installation tool to avoid damaging the seal edges.
Q: What common mistakes cause early failure of this seal ring?
A: Common issues include overstretching or twisting the ring during installation, misaligning the split gaps, using the wrong ring size for the groove, and scratching the seal edges on the cylinder bore or piston.
Q: How long can a properly installed filled PTFE piston seal ring last?
A: With clean hydraulic fluid, correct installation, and operation within rated pressure and temperature limits, it can last thousands of operating hours. Lifespan is reduced by contaminated fluid, high cycle rates, or excessive side loads on the piston.
Q: Can I reuse a piston seal ring after removing it?
A: No, it is not recommended. Once removed from the groove, the ring can lose its tension and dimensional stability. Even minor deformation can lead to fluid bypass and reduced performance. Always install new rings during reassembly.
