Value Collection ZMSCE70131 Epdm O-ring Dash 131 Pack 50

Product Description

The VALUE COLLECTION ZMSCE70131 is a Dash 131 EPDM O-ring designed for static and dynamic sealing applications where resistance to heat, hot water, steam, and phosphate ester hydraulic fluids is required. The ring measures 1.688 inches inside diameter and 1.875 inches outside diameter, with a cross-section thickness of 0.0937 inches (3/32 inches). Hardness is rated at 70 Shore A, which falls in the hard range and provides reliable compression set resistance under sustained sealing loads. Each package contains 50 rings. This part is installed by licensed plumbers, HVAC technicians, and hydraulic system technicians working on fluid sealing applications.

This O-ring is suited for residential and commercial applications involving hot water systems, steam service, and phosphate ester type hydraulic fluids. It also carries a notable resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it relevant to aerospace ground support and maintenance work in addition to standard trade applications. The round cross-section profile fits standard Dash 131 O-ring grooves and is compatible with hot water plumbing assemblies, steam fittings, and hydraulic manifold connections where EPDM compound is the specified material.

Key Features

• EPDM compound rated for service from -65 degrees F to 300 degrees F
• 70 Shore A hardness for firm compression and consistent sealing under load
• Round cross-section profile fits standard Dash 131 groove dimensions
• Resistant to hot water, steam, and phosphate ester hydraulic fluids
• Suitable for Skydrol fluid environments in commercial aircraft hydraulic systems
• Sold in a package of 50 for job-site and shop stocking

Compatibility

Designed as a standard Dash 131 O-ring replacement for sealing applications requiring EPDM material, including hot water, steam, and phosphate ester hydraulic fluid service as specified by the manufacturer.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system technicians depending on the application. Depressurize and drain the system fully before removing the old O-ring and seating the replacement. Ensure the groove is clean and free of debris before installation. Do not use petroleum-based lubricants with EPDM rings, as they will cause the material to swell and degrade.
