Value Collection ZMSCE70007 Epdm O-ring Dash 007 100 Pack

Product Description

The VALUE COLLECTION ZMSCE70007 is a Dash 007 EPDM O-ring designed for sealing applications that demand resistance to hot water, steam, and phosphate ester hydraulic fluids. The round cross-section ring measures 0.156 inches inside diameter, 0.281 inches outside diameter, and 0.0625 inches thick. With a Shore A hardness rating of 70 and a working temperature range of -65 degrees F to 300 degrees F, this O-ring handles demanding thermal cycles in both hydraulic and plumbing service environments. Each package contains 100 rings, making it practical for service stock and repeat-installation work.

This O-ring is suited for residential and commercial plumbing, HVAC hydronic systems, and industrial hydraulic applications where EPDM compatibility is required. It is particularly well suited for hot water and steam service lines, as well as phosphate ester type hydraulic fluid circuits. The material also provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Plumbing and HVAC technicians will find this ring appropriate for valve stem seals, fitting connections, and pump assemblies that see elevated temperatures or steam exposure.

Key Features

• EPDM material rated for hot water, steam, and phosphate ester hydraulic fluids
• Excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems
• Operating range of -65 degrees F to 300 degrees F for high-temperature service
• Shore A hardness of 70 for reliable compression sealing
• Round cross-section profile for consistent seat contact in standard O-ring grooves
• Sold in a 100-pack for efficient service stocking

Compatibility

Compatible with hot water, steam, and phosphate ester hydraulic fluid systems. EPDM material is not compatible with petroleum-based oils or fuels; verify fluid compatibility before installation.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and hydraulic system mechanics. Shut off and depressurize the system completely before replacing any O-ring seal. Lightly lubricate the ring with a compatible, fluid-appropriate lubricant before seating to prevent tearing during assembly. Do not use petroleum-based lubricants with EPDM rings.
