Top Notch Urethane O Ring With 70 Durometer For Hydraulic Sealing Built Tough To Handle Any Gig Delivers Smooth Leak Free Performance In Tricky Conditions Bulk Pack Of 1000 Units

Polyurethane O Rings 70 Durometer Hydraulic Seals
✔️ Cast Polyurethane 70 Duro Hydraulic Fluid Compatible

This bulk pack of one thousand urethane o rings gives solid sealing for hydraulic lines and heavy equipment joints. Cast polyurethane handles grind and flex better than standard rubber while holding up to six thousand pounds per square inch. Mechanics use these for moving piston rods, vibration dampening rigs, and damp spots where mineral oils or light chemicals show up often.

✅ seventy shore A Hardness Rating Balances Flexibility And Load Bearing Capacity
✅ Resists Wear From Hydraulic Fluids Aliphatic Solvents And Salt Water Exposure
✅ Handles Compression Loads While Maintaining Shape Over Repeated Stress Cycles

💡 What advantages do polyurethane o rings offer over nitrile rubber in hydraulic systems?
Cast polyurethane takes harder hits than synthetic rubber thanks to tight cross linking and shock absorption qualities.
- Higher tensile strength keeps the ring seated firmly under fast pressure jumps
- Lower compression set locks the grip tight across endless push pull actions
- Scratch and rub proof makeup saves cash by cutting down shop downtime
- Handy upgrade whenever cheap elastomers blow out or leak on busy job sites
