Value Collection ZMSCE70314 Epdm O-ring Dash 314 70-pack

Product Description

The VALUE COLLECTION ZMSCE70314 is a Dash 314 EPDM O-ring with a 0.750-inch inside diameter, 1.125-inch outside diameter, and a 0.1875-inch round cross-section thickness. Made from Ethylene Propylene Diene Monomer (EPDM), it delivers strong resistance to hot water, steam, and phosphate ester hydraulic fluids, as well as Skydrol fluids used in commercial aircraft hydraulic systems. Rated at 70 Shore A hardness, this O-ring is classified as hard and is suited for sealing applications that require consistent performance across a wide temperature range. HVAC technicians, plumbers, and industrial maintenance professionals install this type of seal in valves, fittings, and fluid-handling assemblies.

This O-ring is well suited for residential and commercial plumbing systems, hydronic heating circuits, steam service, and industrial hydraulic applications that use phosphate ester-based fluids. Its EPDM compound performs reliably in hot water and steam environments, making it a practical choice for boiler system service, water treatment equipment, and similar wet-side mechanical applications. This item is packaged in a quantity of 70 per package, which supports service fleets and shop inventory needs.

Installation Notes

EPDM O-rings are installed by licensed plumbers, HVAC technicians, and qualified maintenance technicians. Before replacing an O-ring, shut off and depressurize the system and allow it to cool if hot water or steam is involved. Inspect the mating groove and seating surface for damage or debris before installing the new seal. Do not use petroleum-based lubricants with EPDM; use a compatible water-based or silicone lubricant for installation assistance.
