Value Collection ZMSCE70260 O-ring Dash 260 Epdm 70A

Product Description

The VALUE COLLECTION ZMSCE70260 is a Dash 260 EPDM O-ring designed for static and dynamic sealing applications in fluid handling, hydraulic, and process piping systems. With a 6.5-inch inside diameter, 6.75-inch outside diameter, and 0.125-inch cross-section thickness, this round-profile ring seats into standard Dash 260 grooves. Ethylene propylene diene monomer construction provides broad chemical compatibility, including strong resistance to hot water, steam, and phosphate ester hydraulic fluids. Rated for a temperature range of -65 to 300 degrees F, it suits demanding thermal environments. Plumbers, HVAC technicians, and industrial maintenance trades commonly install this size.

This O-ring is appropriate for use in residential and commercial plumbing systems, HVAC equipment, and hydraulic circuit assemblies where EPDM chemical compatibility is required. It is rated compatible with hot water, steam, and phosphate ester fluids, including Skydrol-type hydraulic fluids used in commercial aircraft hydraulic systems. The 70 Shore A hardness rating places it in the hard category, making it suitable for moderate-pressure sealing duties. Each package contains 8 rings, with a minimum order of 1 package.

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluids. Also suitable for use in systems handling Skydrol-type fluids found in commercial aircraft hydraulic circuits. Designed as an OEM-style replacement for standard Dash 260 O-ring applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Depressurize and drain the system fully before removing the old seal and installing the replacement ring. Inspect the groove for nicks, burrs, or debris that could damage the sealing surface. Do not overstretch the ring during installation, as this can permanently reduce its sealing effectiveness.
