Value Collection ZMSCH70MD007 O-ring Dash 007 Nbr 50-pack

Product Description

The VALUE COLLECTION ZMSCH70MD007 is a Dash 007 nitrile butadiene rubber (NBR) O-ring with a 0.156 inch inside diameter, 0.281 inch outside diameter, and a 0.0625 inch (1/16 inch) round cross section. Rated at 70 durometer (hard), this O-ring is designed for static and dynamic sealing applications across HVAC, plumbing, and fluid-handling systems. NBR is the most widely used O-ring elastomer in the trades due to its excellent resistance to petroleum-based fluids, strong compression set resistance, and solid tear and abrasion performance. Each package contains 50 rings. Licensed trade professionals and maintenance technicians are the primary installers.

This O-ring is suited for use in residential and light commercial HVAC equipment, refrigeration systems, plumbing fittings, hydraulic assemblies, and general fluid-handling components where petroleum-product compatibility is required. The Dash 007 sizing is a standard AS568 designation, making this ring a straightforward drop-in replacement in any application specifying a 007-series O-ring. Operating temperature range spans -40 degrees F to 250 degrees F, covering the majority of field service conditions encountered in HVAC and mechanical trades. This part is not FDA approved for direct food-contact applications.

Compatibility

Designed as a standard AS568 Dash 007 O-ring replacement for any application requiring an NBR seal with 0.156 inch ID and 0.281 inch OD. Compatible with petroleum products. Not recommended for use with ozone-generating environments or direct sunlight storage. Not FDA approved for food-contact use.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and isolate the system before removing or replacing O-rings. Inspect the groove and mating surfaces for nicks or debris before seating the new ring. Avoid storing NBR O-rings near electric motors, compressors, or other ozone-generating equipment, as ozone accelerates elastomer degradation.
