Value Collection ZMSCE70225 Epdm O-ring Dash 225 10 Pack

Product Description

The VALUE COLLECTION ZMSCE70225 is a Dash 225 EPDM O-ring designed for static and dynamic sealing applications in plumbing, HVAC, and industrial fluid systems. Measuring 1.875 inches inside diameter, 2.125 inches outside diameter, and 0.125 inches thick, it features a round cross section and a Shore A hardness of 70. The ethylene propylene diene monomer (EPDM) compound provides strong resistance to hot water, steam, and phosphate ester hydraulic fluids, making it a dependable choice for licensed plumbers, HVAC technicians, and maintenance professionals working on fluid handling systems.

This O-ring is suited for residential and commercial applications involving hot water lines, steam fittings, and phosphate ester type hydraulic circuits. The EPDM compound is also noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, broadening its use to aviation maintenance environments. Its Dash 225 designation follows the standard AS568 sizing system, allowing straightforward cross-reference into existing seal inventories. Each package contains 10 O-rings.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off and depressurize the system completely before removing the existing seal or installing a new one. Ensure the seating groove is clean and free of debris before seating the O-ring. Verify the groove dimensions match the Dash 225 profile to avoid under- or over-compression of the seal.
