Value Collection ZMSCH70924 O-ring Dash 924 Nbr 70

Product Description

The VALUE COLLECTION ZMSCH70924 is a Dash 924 O-ring boss gasket designed for use with straight-thread tube fittings in fluid and hydraulic systems. Made from Nitrile Butadiene Rubber (Buna-N), it measures 1.72 inches inside diameter, 1.956 inches outside diameter, and 0.118 inches thick with a round cross section. Rated at 70 durometer (hard), this O-ring delivers excellent resistance to petroleum products, solid compression set performance, and strong tear and abrasion resistance. It is the most widely used O-ring elastomer in trade and industrial applications. Each package contains 100 pieces.

This O-ring is suited for residential and commercial plumbing, HVAC, and hydraulic system applications where petroleum-based fluids or lubricants are present. Its Buna-N construction makes it a standard choice for O-ring boss (ORB) fittings on straight-thread tube connections in fuel, oil, and hydraulic lines. It meets SAE and MIL-Spec standards, making it appropriate for both commercial maintenance and light industrial service work. Plumbers, HVAC technicians, and hydraulic system technicians are the primary installers of this seal type.

Compatibility

Designed as an O-ring boss gasket for straight-thread tube fittings; compatible with petroleum products and petroleum-based fluids. Not recommended for use in direct sunlight exposure or near ozone-generating equipment such as electric motors. Not FDA approved.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system technicians depending on the application. Shut off fluid supply and relieve system pressure before removing or replacing any O-ring or fitting seal. Lubricate the O-ring with a compatible petroleum-based lubricant before seating to prevent tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this can degrade the elastomer over time.
