Value Collection ZMSCE70234 Epdm O-ring Dash 234 25 Pack

Product Description

The VALUE COLLECTION ZMSCE70234 is a Dash 234 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in plumbing, HVAC, and industrial fluid systems. It measures 3 inches inside diameter, 3.25 inches outside diameter, and 0.125 inches thick. The ethylene propylene diene monomer compound provides a Shore A hardness of 70 and a working temperature range of -65 degrees F to 300 degrees F. This O-ring is sold in a package of 25 and is a standard trade-supply item installed by plumbers, HVAC technicians, and mechanical contractors.

This O-ring is suited for hot water and steam service, as well as phosphate ester type hydraulic fluids. It also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it applicable to aerospace ground-support maintenance alongside standard plumbing and HVAC work. Typical installation scenarios include pump flanges, valve bonnets, pipe unions, and equipment access covers where a Dash 234 size seal is specified. The black color indicates standard EPDM compound, consistent with common OEM seal specifications in water and steam piping assemblies.

Compatible with hot water, steam, and phosphate ester hydraulic fluid systems. Designed as a Dash 234 standard O-ring replacement for any application specifying a 3-inch ID EPDM seal with a 0.125-inch cross section.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or mechanical contractors. Always shut off water supply or depressurize the system and allow components to cool before replacing seals. Clean the O-ring groove of debris, corrosion, and old sealant before seating the new ring. Do not use petroleum-based lubricants with EPDM compounds; use a compatible water-based or silicone lubricant approved for the fluid service.
