211 Quad Ring Buna NBR X Profile Seal 70D Low Friction O Ring Set Pack Of 25 For Reciprocating Equipment Including Hydraulic Cylinders Pneumatic Actuators Pumps And Valves With Non Roll Grooves And Leakage Prevention

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
