Urethane / Polyurethane Seals
In situations where temperatures range from -65F to + 200F a polyurethane seal is often the most economical and best design choice.
Besides being inexpensive, urethanes are tough, abrasion/wear resistant, and able to take shock loads better than most elastomers.
Check our PolyKing™ catalog for the widest range of urethane U-cups for rod or piston seal applications. We currently have molds, for most sizes, ready to use on on our 22 to 300 ton presses.
