Value Collection ZMSCH90007 O-ring Dash 007 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90007 is a Dash 007 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 0.156 inches inside diameter, 0.281 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 90 durometer (extra hard), it delivers excellent compression set resistance along with strong tear and abrasion resistance. The temperature range spans -40 to 250 degrees F, making it suitable for use across a broad range of HVAC, plumbing, and mechanical service environments. Licensed trades and service technicians rely on this O-ring for dependable seals in petroleum-based fluid systems.

This O-ring is used wherever a Dash 007 size seal is required in residential and light commercial systems. Common applications include refrigerant service fittings, hydraulic lines, fuel system connections, compressor service ports, and general plumbing fittings that contact petroleum-based fluids. Its Buna-N compound provides excellent resistance to petroleum products, oils, and fuels, making it a go-to choice for HVAC techs, plumbers, and mechanical contractors working on systems that carry these media. It is not recommended for applications involving ozone, strong oxidizing agents, or direct sunlight exposure during storage.

Compatibility

Designed for use with petroleum products and compatible fluids in standard Dash 007 O-ring groove applications. Compatible material designation is petroleum products per manufacturer specs. Not FDA approved; not intended for food-grade or potable water contact service.

Installation Notes

O-rings should be installed by a qualified technician following the equipment manufacturer's service procedures. Always depressurize and de-energize the system before replacing O-ring seals. Lubricate the O-ring with a compatible fluid or grease prior to installation to prevent pinching or tearing during assembly. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure can degrade Buna-N compound over time.
