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.
