Value Collection ZMSCE70141 Epdm O-ring Dash 141 70 Duro 25pk

Product Description

The VALUE COLLECTION ZMSCE70141 is a Dash 141 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in fluid handling systems. It measures 2.313 inches inside diameter, 2.5 inches outside diameter, and 0.094 inches thick. The compound is Ethylene Propylene Diene Monomer with a 70 Shore A hardness rating, making it well suited for environments involving hot water, steam, and phosphate ester type hydraulic fluids. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this ring as a replacement seal wherever the Dash 141 standard size is called out.

This O-ring performs across a wide service temperature range of -65 degrees F to 300 degrees F. It is commonly used in plumbing systems, HVAC hydronic circuits, steam service connections, and hydraulic assemblies that use phosphate ester fluids. The EPDM compound also exhibits excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a cross-industry sealing solution. Each order is fulfilled in a package quantity of 25 rings, suitable for stocking maintenance kits or completing multiple connection points in a single service call.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and drain the system before removing the old seal. Inspect the seating groove for nicks or corrosion that could compromise the new seal. Do not use petroleum-based lubricants with EPDM compounds; use a compatible silicone or water-based lubricant when seating the ring.
