Premium Cast Polyurethane Seals For Fluid Systems Online
✔️ A90 Hard Compound With Six Kilopounds Tensile Capacity

These bulk o rings are cast urethane seals designed to handle harsh industrial environments and heavy pressure loads. You will typically install them in hydraulic cylinders, pneumatic systems, and chemical processing equipment where standard rubber quickly degrades. They come in a pack of one hundred units sized at ten inch inner diameter with a quarter inch cross section. ✅ Cast polyurethane elastomer with an A90 durometer rating for rigid sealing
✅ Temperature tolerance spanning negative sixty five to two hundred seventy five degrees fahrenheit
✅ Resistant to mineral oils petroleum products aliphatic solvents and weak acidic solutions

💡 What makes cast urethane seals a handy choice for high pressure hydraulic cylinder maintenance?
This tough polymer beats soft synthetic rubbers when you need tight friction control around sliding rods.
- They resist swelling in mineral oils and petroleum mixes that eat away standard Buna seals
- The stiff polymer wall handles crushing forces and sudden impacts without tearing loose from grooves
- Factory cut dimensions match common industrial housing slots so swap outs stay hassle free on the floor
