Value Collection ZMSCH70MD125 O-ring Dash 125 Nbr

Product Description

The VALUE COLLECTION ZMSCH70MD125 is a Dash 125 O-ring manufactured from Nitrile Butadiene Rubber (NBR), the most widely used elastomer in fluid sealing applications. It measures 1.299 inches inside diameter, 1.5 inches outside diameter, and 0.0937 inches (3/32 inches) thick with a round cross-section profile. Rated at 70 Shore A hardness, this O-ring delivers reliable static and dynamic sealing in systems that handle petroleum-based fluids. It is installed by plumbers, HVAC technicians, hydraulic system mechanics, and industrial maintenance professionals across a broad range of equipment types.

This O-ring is suited for use in hydraulic fittings, fluid connectors, valve stems, pump housings, and general-purpose sealing applications where petroleum product exposure is expected. Its operating temperature range spans -40 degrees F to 250 degrees F, making it appropriate for both low-temperature startup conditions and moderate-heat service environments. It is commonly specified in residential and commercial HVAC systems, plumbing assemblies, and light industrial hydraulic circuits wherever a Dash 125 cross-section seals a standard-dimension port or fitting bore.

Key Features

• Nitrile Butadiene Rubber construction with excellent resistance to petroleum-based fluids and lubricants
• 70 Shore A hardness rating provides a firm, durable seal with strong compression set resistance
• Rated for service from -40 degrees F to 250 degrees F
• Round cross-section profile conforms to standard Dash 125 O-ring groove dimensions
• Good tear and abrasion resistance extends service life in dynamic sealing applications
• Sold in a package quantity of 10, with a minimum order quantity of 1 package

Compatibility

Designed as a standard Dash 125 O-ring replacement compatible with petroleum-product service environments. Compatible materials include petroleum-based fluids, lubricants, and hydraulic oils. Not recommended for use with ozone-generating equipment or in direct sunlight storage; should not be used in applications requiring FDA food-contact approval.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and isolate the system before removing the old O-ring and seating the replacement. Lightly lubricate the O-ring with a compatible petroleum-based or system-fluid lubricant before installation to prevent tearing during assembly. Avoid using sharp tools near the sealing surface, and inspect the groove for scoring or debris before seating the new ring.
