Value Collection ZMSCE70033 Epdm O-ring Dash 033 Pack 50

Product Description

The VALUE COLLECTION ZMSCE70033 is an EPDM (Ethylene Propylene Diene Monomer) O-ring with a round cross section, designed for static and dynamic sealing applications in plumbing, HVAC, and fluid-handling systems. This Dash 033 O-ring measures 2 inches inside diameter, 2.125 inches outside diameter, and 0.0625 inches thick. Rated at 70 durometer (hard), it maintains a reliable seal across a wide temperature range of -65 degrees F to 300 degrees F. Installation is performed by licensed plumbers, HVAC technicians, and mechanical contractors where a dependable elastomeric seal is required in demanding service environments.

This O-ring is well suited for residential and commercial applications involving hot water lines, steam systems, and phosphate ester type hydraulic fluids. It also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it applicable in aerospace ground-support and maintenance contexts. The EPDM compound is specifically chosen where exposure to water, steam, and select synthetic hydraulic fluids is expected. Each order is fulfilled in a package quantity of 50 pieces, suitable for service stock or multi-unit jobs.

Installation Notes

O-rings of this type are typically installed by licensed plumbers, HVAC technicians, or mechanical contractors. Before installation, depressurize and drain the system completely to prevent injury and ensure a proper seat. Inspect the groove and mating surfaces for nicks or burrs that could compromise the seal. Follow applicable codes such as IPC or IFGC for plumbing and mechanical applications, and verify that EPDM is chemically compatible with all fluid media present in the system.
