Value Collection ZMSCE70NSF008 O-ring Dash 008 Epr 25-pack

Product Description

The VALUE COLLECTION ZMSCE70NSF008 is an ethylene propylene rubber (EPR) O-ring with a round cross section, sold in a pack of 25. It measures 0.188 inches inside diameter, 0.312 inches outside diameter, and 0.0625 inches thick, conforming to the Dash 008 standard sizing. Rated at 70 Shore hardness, this O-ring handles a working temperature range of -65 degrees F to 300 degrees F, making it well suited for high-temperature sealing applications. Plumbers, HVAC technicians, and industrial maintenance pros use EPR O-rings where water, steam, or phosphate ester hydraulic fluids are present.

This O-ring is designed for sealing in systems that carry hot water, steam, and phosphate ester type hydraulic fluids. It also demonstrates resistance to some acids, alkalies, and ozone, expanding its usefulness in light chemical-contact environments. It meets NSF 61 certification requirements, making it appropriate for use in potable water system components. Each package contains 25 pieces, supporting both service calls and small production runs without excess ordering.

Key Features

• Ethylene propylene rubber (EPR) construction rated for hot water, steam, and phosphate ester hydraulic fluids
• Working temperature range: -65 degrees F to 300 degrees F
• 70 Shore hardness (hard rating) for reliable compression sealing under pressure
• NSF 61 certified for use in potable water system components
• Excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems
• Round cross section, Dash 008 standard sizing for consistent fitment
• Pack of 25 pieces per package

Compatibility

Compatible with systems handling hot water, steam, phosphate ester type hydraulic fluids, some acids, alkalies, and ozone-exposed environments. NSF 61 approval supports use in potable water applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Shut off all fluid supply and relieve system pressure fully before replacing any O-ring. Inspect the seating groove for scoring or debris before installing the new ring. Lubricate the O-ring with a fluid compatible with EPR compound — avoid petroleum-based greases, which degrade ethylene propylene rubber.
