Heavy Duty Urethane O Rings 70D Bulk Pack Of 1000
✔️ Cast poly 2 1/8 inch ID 6000 psi pull 350 pct elongation

This bulk pack of cast polyurethane compression seals delivers heavy duty performance for demanding machinery repair jobs. Workers rely on these durable urethane o rings to lock in pressure across hydraulic cylinders, conveyor systems, and rolling equipment where standard rubber fails quickly under friction or stress.

✅ 70 durometer hardness optimized for high pressure hydraulic operations
✅ Measures 2 1/8 inches along the inner diameter with 3/16 inch cross section
✅ Pulls up to 6000 psi tensile strength while holding tight against salt water
✅ Handles weak acids bases and petroleum products without breaking down fast

💡 What makes cast polyurethane o rings a superior alternative to Buna N for high pressure linear slide applications?
Slipping this rugged blend into your rig is a handy trick when you need parts that toss out grime and handle sudden pressure spikes. You get a stiff rubber substitute that locks tight and refuses to budge. See why machinists dig this setup over flimsy cheapo rings.
- Shoves aside metal shavings and abrasive debris without tearing loose mid-shift
- Holds its exact outline through wide thermal swings instead of warping under heat
- Fights off mineral oil blends and weak alcohol solvents without getting soft or bloated
