Premium Buna NBR Quad Ring Set for Reciprocating Gear
✔️ Pack of 25 low-friction Buna NBR quad rings, 0.8125 inch ID by 1/8 inch cross-section, ideal for hydraulic and pneumatic sealing in pumps and valves.

This quad ring set features Buna NBR X-profile seals designed for dynamic applications, commonly used in reciprocating equipment like hydraulic cylinders, pneumatic actuators, pumps, and valves to prevent leaks and handle movement smoothly.

✅ Low friction design prevents rolling in grooves during reciprocating motion
✅ Overcomes O-Ring issues like high friction and spiral failures for better performance
✅ Retains lubricant in grooves to reduce wear and extend seal life
✅ Requires less squeeze, lowering breakaway force in dynamic sealing setups
✅ Offers twice the sealing surface compared to standard O-Rings for enhanced efficiency

💡 Why are quad rings preferred over O-rings in industrial sealing? A solid choice for tough jobs, quad rings step up with key perks that make them a go-to for sealing needs. - They cut down on friction and wear, boosting reliability in moving parts - The design keeps lubricant in place, easing startup and cutting maintenance - They seal better under pressure, handling compression set without leaking - Ideal for setups with back-and-forth motion, avoiding common O-ring pitfalls
