Value Collection ZMSCH90016 O-ring Nbr Dash 016 100-pack

Product Description

The VALUE COLLECTION ZMSCH90016 is a Dash 016 Nitrile Butadiene Rubber (NBR/Buna-N) O-ring sold in a 100-piece pack. It measures 0.625 inches inside diameter, 0.75 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 90 durometer (Extra Hard), it handles temperatures from -40 degrees F to 250 degrees F and is compatible with petroleum-based fluids. HVAC technicians, plumbers, and mechanical contractors use this seal in hydraulic fittings, fuel systems, pneumatic assemblies, and refrigerant service valves where a reliable, compression-resistant seal is required.

This O-ring is suited for residential and commercial applications involving petroleum-based lubricants, oils, fuels, and hydraulic fluids. The Dash 016 sizing is a standard AN/SAE dimension found in a wide range of fittings, valves, and manifold assemblies across HVAC, plumbing, and fluid-handling systems. The extra-hard 90 durometer rating makes it well suited for higher-pressure service points where softer elastomers tend to extrude. It meets SAE and MIL-Spec standards and is commonly stocked by technicians performing routine seal replacements in the field.

Key Features

• Buna-N (NBR) elastomer provides excellent resistance to petroleum products, oils, and fuels
• 90 durometer Extra Hard rating resists extrusion in higher-pressure applications
• Operating range of -40 degrees F to 250 degrees F suits most HVAC and plumbing service environments
• Round cross section, Dash 016 sizing conforms to SAE and MIL-Spec standards
• Strong tear and abrasion resistance extends service life in dynamic and static sealing applications
• Pack of 100 supports field stocking and bulk replacement jobs

Compatibility

Compatible with petroleum products, hydraulic oils, fuels, and similar fluid media. Designed as a standard SAE Dash 016 replacement O-ring for use in fittings, valves, and assemblies that call for a 0.625 inches ID by 0.75 inches OD by 0.0625 inches thick NBR seal. Not recommended for use with ozone exposure, direct sunlight storage, or near motors and other electrical equipment that generate ozone.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified mechanical trades depending on the application. Always depressurize and de-energize the system before replacing O-rings, and drain or isolate any fluid lines as required. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Avoid twisting the O-ring in the groove, as a twisted seal will not provide reliable compression.
