Value Collection ZMSCE70025 O-ring Dash 025 Epdm 50-pack

Product Description

The VALUE COLLECTION ZMSCE70025 is a Dash 025 EPDM O-ring designed for fluid sealing in plumbing, hydraulic, and mechanical systems. It measures 1.188 inches inside diameter and 1.313 inches outside diameter with a 0.0625-inch (1/16-inch) thick round cross section. The compound is ethylene propylene diene monomer (EPDM) with a hardness of 70 Shore A, rated for a temperature range of -65 degrees F to 300 degrees F. This O-ring is sold in packs of 50, making it a practical bench stock choice for plumbers, HVAC technicians, and mechanical contractors who service steam, hot water, and hydraulic systems regularly.

This O-ring is suited for residential and commercial applications involving hot water lines, steam service, and phosphate ester type hydraulic fluids. It also delivers strong resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it relevant to aviation maintenance environments. Typical install scenarios include replacing worn seals in valves, fittings, pumps, and manifold connections where EPDM compatibility with water and steam is required. The round cross section allows it to seat properly in standard dash 025 O-ring grooves.

Key Features

Compatibility

Compatible with hot water, steam, and phosphate ester hydraulic fluid systems. Also recommended for applications involving Skydrol fluids in commercial aircraft hydraulic systems. Fits standard Dash 025 O-ring grooves per AS568 sizing.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanical maintenance personnel. Always depressurize and drain the system before removing or replacing any O-ring seal. Inspect the groove and mating surfaces for damage or debris before seating the new O-ring. Do not use petroleum-based lubricants with EPDM compound; use a compatible water-based or silicone-free assembly lubricant if needed.
