Value Collection ZMSCE70911 Epdm O-ring Dash 911

Product Description

The VALUE COLLECTION ZMSCE70911 is a Dash 911 EPDM O-ring designed for sealing applications in fluid and hydraulic systems. Manufactured from Ethylene Propylene Diene Monomer (EPDM) with a round cross section, this O-ring measures 0.863 inches inside diameter, 1.095 inches outside diameter, and 0.116 inches thick. It carries a Shore A hardness rating of 70, placing it in the hard range. Rated for service from -65 degrees F to 300 degrees F, it is suited for hot water, steam, and phosphate ester hydraulic fluid applications. Licensed HVAC technicians, plumbers, and hydraulic system technicians install this type of seal in both residential and commercial service work.

This O-ring is particularly effective as an O-Ring Boss gasket for straight-thread tube fittings. It is compatible with hot water, steam, and phosphate ester type hydraulic fluids, and also provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Its EPDM construction makes it a reliable choice wherever resistance to high-temperature water or steam exposure is required in plumbing, HVAC, and hydraulic piping assemblies. The package quantity is 70 pieces with a minimum order quantity of 1.

Installation Notes

Installation of O-ring seals is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and de-energize the system and allow components to cool before replacing any seals. Inspect the seating groove for nicks, burrs, or debris before installation, and lubricate the O-ring with a compatible fluid to prevent tearing during assembly. Follow applicable IPC or equipment manufacturer guidelines for torque and fitting assembly procedures.
