Rheodyne Vespel Rotor Seal for 7000L - 7000-016

Rheodyne Vespel® Rotor Seal for 7060L

Product Number: 7000-016

This Vespel Rotor Seal is a polymeric disc that ensures a high pressure seal against the stator. Vespel offers high heat resistance, reliable mechanical strength and broad chemical resistance. It is for valve model 7000L.

The standard rotor seal in many Rheodyne® manual valves is made from a Vespel® blend. This polyimide has low wear and high chemical resistance. Vespel tolerates a pH range of 0 to 10. Solutions more basic than pH 10 dissolve Vespel which damages the rotor seal. If you use any solutions above pH 10, Rheodyne recommends a PEEK blend rotor seal. PEEK offers a high chemical resistance and versatility, and will tolerate the entire pH range from 0 to 14. ETFE blend rotor seals are appropriate for use in applications where PEEK is not generally acceptable, such as when methylene chloride or DMSO in higher concentrations is being used.
