Udel PSU (polysulfone) is a rigid, high-strength, semi-tough, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate. It retains its good mechanical properties when exposed to steam and other sterilization techniques.

Udel  PSU excels in many fluid-handling applications and has successfully replaced brass in pressurized hot water applications for over 20 years. It exhibits low creep under a sustained load at elevated temperatures and can withstand continuous exposure to hot chlorinated water.
