Gruvlok Grade T Nitrile Gasket

This Gruvlok gasket uses Grade T nitrile material for sealing in plumbing systems. It fits a 2-1/2 inch connection and carries NSF certification with ASTM D2000 compliance. The part is manufactured new for use with specific Gruvlok components.

Temperature performance from -20 to 180 degrees F

The nitrile construction maintains sealing integrity across a wide temperature range from -20 to 180 degrees F. This sustained thermal tolerance supports reliable operation in both cold-water and heated plumbing circuits without degradation. The material resists hardening or softening that would compromise the joint over time.

NSF certified for potable water contact

NSF certification confirms the gasket meets health and safety standards for drinking water systems. This single qualification determines suitability for potable water installations where code compliance is mandatory. Buyers needing non-potable or industrial-only seals should verify their local requirements differ.
