Solid As A Rock Urethane O Rings For Heavy Duty Hydraulic Systems Built Tough With Top Notch Elongation And Chemical Resistance Perfect For Everyday Grind Pack Of Two Fifty

Heavy Duty Urethane O Rings Ideal For Hydraulic Seals
✔️ Pack of two rated A90 durometer with -65 to 275 F range

These solid urethane stopper seals deliver serious leak blocking power for heavy equipment operators running high pressure fluid systems. You will find them working steadily inside hydraulic cylinders, piston rods, and industrial machinery where rubber fails under stress. Each ring measures fifteen inch inner diameter with a quarter inch outer extension and eighth inch cross section.

✅ Cast material delivers six thousand psi tensile strength plus massive tear resistance
✅ Hardness sits at A90 durometer for superior grip against grinding wear and tear
✅ Compatible with mineral oils petroleum products and light chemical washdowns
✅ Handles sliding motion and rotational setups across factory floors and job sites

💡 How do heavy duty hydraulic cylinders benefit from using cast polyurethane seals Mechanics choose these handy components when standard rubber gives up under pressure - Six thousand pound tensile limit blocks leaks during intense pump spikes - Wide thermal tolerance prevents hardening when heat builds up under heavy loads - High elongation percentage absorbs shock without cracking around rotating shafts - Resists oil exposure while keeping a steady grip on wet metal rod surfaces
