Value Collection ZMSCE70108 Epdm O-ring Dash 108 100-pack

Product Description

The VALUE COLLECTION ZMSCE70108 is a Dash 108 EPDM O-ring sold in a pack of 100, designed for sealing applications in fluid and thermal systems. It features a round cross section with an inside diameter of 0.25 inches, an outside diameter of 0.438 inches, and a thickness of 0.0937 inches. The compound is Ethylene Propylene Diene Monomer, rated at 70 durometer hardness, and is formulated for compatibility with hot water, steam, and phosphate ester type hydraulic fluids. Licensed HVAC technicians, plumbers, and hydraulic system technicians install these as precision sealing elements in high-temperature and fluid-handling assemblies.

This O-ring is suited for residential and commercial applications involving hot water lines, steam systems, and phosphate ester hydraulic circuits. It performs across a wide service temperature range of -65 degrees F to 300 degrees F, making it appropriate for demanding thermal environments. The EPDM compound also provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, extending its use into aerospace ground support and MRO contexts. Packs of 100 support high-volume service operations and stocking requirements.

Installation Notes

Install by qualified plumbers, HVAC technicians, or hydraulic system mechanics per applicable codes. Always depressurize and drain the system before replacing O-rings. Inspect the mating groove for damage or debris before seating the new ring to ensure a proper seal. Do not use with mineral oil-based fluids or solvents incompatible with EPDM compound.
