Value Collection ZMSCH70038 O-ring Dash 038 Nbr 100 Pack

Product Description

The VALUE COLLECTION ZMSCH70038 is a Dash 038 Nitrile Butadiene Rubber (NBR) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and fluid-handling systems. With an inside diameter of 2.625 inches, an outside diameter of 2.750 inches, and a cross-section thickness of 0.0625 inches, this round-section O-ring meets SAE and MIL-Spec standards. Rated for service between -40 degrees F and 250 degrees F, it delivers reliable sealing in petroleum-based fluid environments. Sold in a package of 100. Installed by licensed plumbers, HVAC technicians, and hydraulic system technicians.

NBR O-rings of this specification are used in residential and commercial applications wherever petroleum-compatible sealing is required. Typical installations include hydraulic fittings, fuel system connections, refrigerant service ports, pump housings, and valve bodies. The 70-durometer hardness rating makes this O-ring suitable for moderate-pressure applications requiring good compression set resistance. This package of 100 supports stocking needs for service shops and field technicians handling repeat sealing work.

Key Features

• Nitrile Butadiene Rubber (Buna-N) construction offers excellent resistance to petroleum products and hydraulic fluids
• Rated from -40 degrees F to 250 degrees F operating temperature range
• 70 Shore A hardness with round cross-section for consistent compression and sealing performance
• Good tear and abrasion resistance for dynamic sealing environments
• Meets SAE and MIL-Spec standards
• Package of 100 units supports shop and fleet service inventories

Compatibility

Compatible with petroleum products and petroleum-based hydraulic fluids. Designed as a standard Dash 038 O-ring replacement suitable for SAE and MIL-Spec compliant sealing applications. Not FDA approved. Store away from direct sunlight, motors, and electrical equipment that may generate ozone.

Installation Notes

O-ring installation should be performed by a qualified technician following system lockout and pressure relief procedures before disassembly. Lubricate the O-ring with a compatible fluid or grease prior to seating to prevent tearing during installation. Avoid twisting the O-ring in the groove, as this causes uneven compression and premature sealing failure. Refer to applicable system service documentation and local plumbing or mechanical codes for torque and assembly specifications.
