Value Collection ZMSCE70126 Epdm O-ring Dash 126 25-pack

Product Description

The VALUE COLLECTION ZMSCE70126 is a Dash 126 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in plumbing, HVAC, and hydraulic systems. It measures 1.375 inches inside diameter, 1.563 inches outside diameter, and 0.094 inches thick. The compound is Ethylene Propylene Diene Monomer (EPDM) with a Shore A hardness of 70, rated Hard. EPDM offers excellent resistance to hot water, steam, and phosphate ester hydraulic fluids, making it a reliable choice for demanding fluid-sealing work. Each purchase includes a pack of 25 O-rings.

This O-ring is well suited for residential and commercial plumbing, HVAC hot-water systems, steam service, and phosphate ester type hydraulic circuits. It is also recognized for its resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a crossover choice for aerospace maintenance technicians. Typical applications include valve seats, pump housings, pipe unions, and fittings where hot water or steam exposure is a regular service condition. The -65 degrees F to 300 degrees F working temperature range covers most heating system and steam-trace applications encountered in the field.

Key Features

• EPDM compound provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids
• Rated for service from -65 degrees F to 300 degrees F
• Shore A hardness of 70 (Hard) for reliable compression and seal retention
• Round cross section, Dash 126 standard sizing for consistent replacement fitment
• Resistant to Skydrol hydraulic fluids used in commercial aircraft systems
• Sold in a pack of 25 for job-lot or service-van stocking

Compatibility

Compatible with hot water, steam, and phosphate ester hydraulic fluid systems. Designed as a standard Dash 126 EPDM O-ring suitable for valves, pumps, fittings, and hydraulic components requiring a 1.375-inch ID seal in applications with those fluid types.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and isolate the system before removing any fitting or valve component containing an O-ring. Inspect the mating groove for nicks, burrs, or corrosion before seating the new ring. Do not use petroleum-based lubricants with EPDM; use a compatible silicone or water-based assembly lubricant only.
