Value Collection ZMSCE70111 Epdm O-ring Dash 111 Pack of 100

Product Description

The VALUE COLLECTION ZMSCE70111 is a Dash 111 EPDM O-ring with a 0.438 inch inside diameter, 0.625 inch outside diameter, and a 0.0937 inch thick round cross section. Molded from Ethylene Propylene Diene Monomer (EPDM) compound at a Shore A hardness of 70, this O-ring is rated for continuous service from -65 degrees F to 300 degrees F. It is sold in a package of 100 units, making it practical for service shops, maintenance operations, and wholesale restocking. HVAC technicians, plumbers, and industrial maintenance mechanics commonly stock this size for routine seal replacements in hot water, steam, and hydraulic fluid systems.

This O-ring is suited for residential and commercial applications involving hot water lines, steam systems, and phosphate ester type hydraulic fluids. It also carries noted resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a crossover fit for aviation ground support and industrial hydraulic maintenance. The 3/32 inch cross section and standard Dash 111 designation allow straightforward identification when cross-referencing to groove dimensions or OEM seal kits.

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluid systems. Also recommended for applications involving Skydrol fluids used in commercial aircraft hydraulic systems. Designed as an OEM-style replacement O-ring wherever a Dash 111 EPDM seal is specified.

Installation Notes

Shut off system pressure and drain or isolate the affected line before removing the old O-ring. Inspect the groove for scoring or corrosion that could compromise the new seal. Apply a compatible lubricant to the O-ring before seating to prevent pinching or tearing during assembly. Verify that the replacement O-ring groove dimensions match Dash 111 specifications before installation.
