Value Collection ZMSCE70013 Epdm O-ring Dash 013 100-pack

Product Description

The VALUE COLLECTION ZMSCE70013 is a Dash 013 EPDM O-ring designed for static and dynamic sealing applications in plumbing, HVAC, and hydraulic systems. It measures 0.4380 inches inside diameter, 0.5630 inches outside diameter, and 0.0625 inches thick with a round cross-section. The EPDM compound delivers a Shore A hardness of 70 and a working temperature range of -65 degrees F to 300 degrees F, making it suited for hot water, steam, and phosphate ester hydraulic fluids. Each package contains 100 O-rings. Licensed plumbers, HVAC technicians, and hydraulic system technicians are the primary installers of this part.

This O-ring is used in residential and commercial plumbing systems, HVAC equipment, and fluid-handling assemblies where hot water and steam contact seals are required. The EPDM material also provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, as well as phosphate ester type hydraulic fluids. Typical applications include valve stems, pipe fittings, pump housings, and manifold connections where a reliable low-profile face or groove seal is needed.

Key Features

• EPDM compound rated for continuous service from -65 degrees F to 300 degrees F
• Shore A hardness of 70 for reliable groove seating and compression set resistance
• Excellent resistance to hot water, steam, and phosphate ester hydraulic fluids including Skydrol
• Round cross-section profile for consistent sealing across standard Dash 013 gland dimensions
• Sold in a 100-piece package to support service stock and batch repairs

Compatibility

Designed as an OEM-style replacement seal for any Dash 013 O-ring groove application requiring EPDM material compatibility with hot water, steam, or phosphate ester hydraulic fluids.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic systems technician. Depressurize and drain the system fully before removing any existing seals. Inspect the gland groove for burrs or corrosion before seating the new O-ring. Do not use petroleum-based lubricants with EPDM compound, as they will degrade the material; use a compatible water-based or silicone lubricant if needed during assembly.
