Value Collection ZMSCE70375 Epdm O-ring Dash 375 Pack of 5

Product Description

The VALUE COLLECTION ZMSCE70375 is a Dash 375 EPDM O-ring with a round cross section, suited for sealing applications that involve hot water, steam, and phosphate ester hydraulic fluids. It measures 9.5 inches inside diameter, 9.875 inches outside diameter, and 0.1875 inches thick. At 70 Shore A durometer, the hardness rating falls in the hard range, providing firm compression resistance under sustained pressure. Each order ships as a pack of 5 pieces. HVAC technicians, plumbers, and industrial maintenance professionals install this O-ring where a reliable, chemical-resistant seal is required in demanding fluid systems.

This O-ring is designed for use in applications involving hot water, steam, and phosphate ester type hydraulic fluids. It also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a cross-industry sealing solution. Typical installations include large-diameter pipe flanges, valve bonnets, pump housings, and heat exchanger assemblies in both residential and commercial settings. The EPDM compound handles temperature extremes well, rated from -65 degrees F to 300 degrees F, which covers most HVAC and plumbing service conditions.

Key Features

• EPDM construction with 70 Shore A durometer for firm, durable compression sealing
• Temperature range of -65 degrees F to 300 degrees F suits hot water and steam systems
• Compatible with phosphate ester hydraulic fluids and Skydrol aircraft hydraulic fluids
• Round cross-section profile for standard O-ring groove fitment
• Dash 375 designation for straightforward cross-reference and replacement sourcing
• Sold in a pack of 5 pieces to support service stock and single-job needs

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluid systems. Suitable for use in large-diameter sealing applications where an EPDM Dash 375 O-ring is specified.

Installation Notes

Licensed plumbers, HVAC technicians, and industrial mechanics typically install O-rings of this size. Before servicing, depressurize the system fully and allow it to cool to a safe handling temperature. Inspect the groove for nicks, corrosion, or debris before seating the O-ring, as surface defects cause premature seal failure. Do not use petroleum-based lubricants with EPDM; use a compatible water-based or silicone lubricant as appropriate for the fluid being sealed.
