Value Collection ZMSCE70229 Epdm O-ring Dash 229 10-pack

Product Description

The VALUE COLLECTION ZMSCE70229 is a Dash 229 O-ring made from Ethylene Propylene Diene Monomer (EPDM) rubber with a round cross section. It measures 2.375 inches inside diameter, 2.625 inches outside diameter, and 0.125 inches thick. With a Shore A hardness rating of 70, this O-ring provides a firm, reliable seal in demanding fluid system applications. It is rated for service from -65 degrees F to 300 degrees F, making it suitable for high-temperature fluid handling. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in pressurized lines and fittings. Each package contains 10 O-rings.

This O-ring is suited for use in hot water systems, steam lines, and phosphate ester type hydraulic fluid applications. It also delivers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a valid choice for aerospace ground support and industrial hydraulic maintenance. Typical applications include pipe unions, valve stems, pump housings, and hydraulic fittings where a firm, temperature-resistant elastomeric seal is required. This part ships in a package of 10 units, which supports service kit stocking and multi-unit repairs.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Depressurize and drain the system completely before removing the existing O-ring. Inspect the seating groove for scoring or corrosion before installing the new O-ring. Lubricate with a compatible fluid or grease rated for EPDM elastomers to prevent tearing during assembly.
