Value Collection ZMSCH1.5X5 Nitrile O-ring 100 Pack

Product Description

The VALUE COLLECTION ZMSCH1.5X5 is a black nitrile butadiene rubber (Buna-N) O-ring with a round cross section, sized at 5 mm inside diameter, 8 mm outside diameter, and 1.5 mm thickness. Buna-N is the most widely used O-ring elastomer in the trade, valued for its excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. This O-ring is rated for a working temperature range of -40 degrees F to 250 degrees F, making it suitable for a broad range of fluid-sealing applications in HVAC, plumbing, and general mechanical systems. It is sold in a package quantity of 100.

This O-ring is commonly used in fluid system assemblies where petroleum-based oils, fuels, or hydraulic fluids are present. Its Buna-N construction makes it a standard choice for sealing fittings, valves, pumps, and connectors in HVAC equipment, refrigeration systems, plumbing assemblies, and light industrial machinery. The 70-durometer hardness rating provides a balance of flexibility and resistance suitable for static and low-dynamic sealing applications. This item is not FDA approved and should not be used in food-contact applications.

Installation Notes

O-rings of this type are installed by plumbers, HVAC technicians, and mechanical service professionals working on fluid-handling assemblies. Always depressurize and drain the system before replacing seals. Inspect the mating groove and sealing surfaces for scoring or debris before installation. Avoid stretching the O-ring beyond the minimum required to seat it, and do not use petroleum-incompatible lubricants during installation.
