Value Collection ZMSCE70010 Epdm O-ring Dash 010 100-pack

Product Description

The VALUE COLLECTION ZMSCE70010 is an EPDM O-ring with a round cross section, sized at 0.250 inches inside diameter, 0.375 inches outside diameter, and 0.0625 inches thick. It carries a Dash 010 designation and a Shore hardness rating of 70 (Hard). EPDM compound gives this seal strong resistance to hot water, steam, and phosphate ester hydraulic fluids, making it a practical choice for plumbing, HVAC hydronic systems, and industrial fluid-handling applications. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers. This part is sold in a pack of 100.

This O-ring is suited for sealing applications involving hot water systems, steam lines, and phosphate ester type hydraulic fluids. Its EPDM construction also provides noted resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it relevant in both building trades and aerospace maintenance contexts. The wide service temperature range of -65 degrees F to 300 degrees F covers the majority of residential and light-commercial hydronic and steam system operating conditions.

Compatibility

Designed for use in hot water, steam, and phosphate ester hydraulic fluid systems where a Dash 010 EPDM O-ring is specified. Not rated for petroleum-based oils or fuels — verify fluid compatibility before installation.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Depressurize and drain the system before replacing any O-ring seal. Inspect the groove for nicks, corrosion, or debris before seating the new ring. Do not stretch the O-ring beyond its natural diameter during installation, and avoid using petroleum-based lubricants with EPDM compound — use a compatible silicone or water-based lubricant only.
