Value Collection ZMSCE70233 Epdm O-ring Dash 233 25-pack

Product Description

The VALUE COLLECTION ZMSCE70233 is a Dash 233 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in plumbing, HVAC, and industrial fluid systems. It measures 2.875 inches inside diameter, 3.125 inches outside diameter, and 0.125 inches thick. Rated for a hardness of 70 Shore A, this O-ring handles operating temperatures from -65 degrees F to 300 degrees F. The EPDM compound provides strong resistance to hot water, steam, and phosphate ester hydraulic fluids. Each package contains 25 O-rings. Installation is performed by licensed plumbers, HVAC technicians, and hydraulic system service professionals.

This O-ring is suited for residential and commercial plumbing systems, hydronic heating loops, and steam service applications. It is also recommended for use with phosphate ester type hydraulic fluids and is noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Typical install scenarios include pump seals, valve stems, pipe unions, and pressurized fluid fittings where a Dash 233 cross-section profile is specified.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Shut off and depressurize the system completely before removing or installing any O-ring seals. Lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during assembly. Do not overstretch or twist the O-ring during installation, as this can cause premature seal failure.
