5. FAQ
Q: What materials make up this hydraulic seal kit?
A: The kit uses common hydraulic materials: NBR (nitrile rubber) for oil-resistant seals and O-rings, PU (polyurethane) for wear-resistant rod/piston seals, and PTFE-impregnated bronze for the wear ring. The retaining ring is typically spring steel.
Q: What are the key properties of these materials?
A:NBR offers good oil compatibility and flexibility, PU provides high pressure and abrasion resistance, and the bronze wear ring prevents metal-to-metal contact, reducing friction and wear.
Q:What’s the most important installation tip for these seals?
A: Always lubricate new seals with clean hydraulic oil before installation, use soft tools to avoid damaging seal lips, and ensure the retaining ring is fully seated to prevent seal extrusion under pressure.
