Rheodyne Rotor Seals

The rotor seal is the polymeric disc that makes a high pressure seal against the stator or stator face seal. The seal wears with use and is one of the only parts that may need routine replacement.

Stators are available in 316 stainless steel, PEEK™ and proprietary materials. Stators need replacement only if the ports or sealing surfaces become damaged. Avoid damage from use of improper injection needles by referring to the "Using Proper Syringe Needles" Application Note.

Please Note: Rotor seals for MX Series II™ Modules are available in RheBuild® Kits. Stators for MX Series II Modules are available on this page. MX (Series I) Module rotor seals are available in RheBuild Kits. Stators.
