Value Collection ZMSCE70231 O-ring Dash 231 Epdm

Product Description

The VALUE COLLECTION ZMSCE70231 is a Dash 231 EPDM O-ring designed for sealing applications that demand resistance to heat, steam, and hydraulic fluids. It measures 2.625 inches inside diameter, 2.875 inches outside diameter, and 0.125 inches thick, with a round cross-section profile and a Shore A hardness of 70. Ethylene Propylene Diene Monomer construction provides reliable performance across a wide temperature range, from -65 degrees F to 300 degrees F. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this part in fluid and pressure sealing assemblies.

This O-ring is suited for use with hot water, steam, and phosphate ester type hydraulic fluids. It also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a practical choice across plumbing, HVAC, and aerospace maintenance applications. The Dash 231 designation is a standard sizing reference used widely in trade and industrial sourcing. Sold in packages of 25 units, with a minimum order quantity of 1.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off system pressure and drain the line or assembly before removing the old O-ring. Inspect the groove for burrs or debris that could damage the new seal. Lubricate the O-ring with a compatible fluid before seating to prevent pinching or tearing during assembly.
