Value Collection ZMSCH70227 O-ring Dash 227 Nbr 50-pack

Product Description

The VALUE COLLECTION ZMSCH70227 is a Dash 227 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 2.125 inches inside diameter, 2.375 inches outside diameter, and 0.125 inches in cross-section thickness, with a round cross-section profile. Rated at 70 Shore A hardness, it provides reliable compression set resistance, tear resistance, and abrasion resistance. The operating temperature range spans -40 degrees F to 250 degrees F, making it a dependable choice for a broad range of hydraulic, pneumatic, and plumbing sealing tasks. Each order includes a package of 50 rings.

This O-ring is suited for use in hydraulic systems, pneumatic lines, fuel systems, and general plumbing assemblies where petroleum-based fluid compatibility is required. Its Buna-N compound delivers excellent resistance to petroleum products, oils, and fuels. Typical install scenarios include pump seals, valve bodies, fittings, and pipe unions in both residential and light commercial mechanical systems. Plumbers, HVAC technicians, and industrial maintenance professionals commonly specify this dash size for standard AN and SAE port sealing applications.

Compatibility

Compatible with petroleum-based products, oils, and fuels. Conforms to SAE and MIL-Spec standards for Dash 227 O-ring dimensions. Not recommended for use with ozone-generating environments or direct sunlight exposure during storage.

Installation Notes

Installation of O-rings should be performed by a qualified plumber, HVAC technician, or mechanical maintenance professional following applicable system shutdown and depressurization procedures. Always relieve system pressure and isolate the fluid source before replacing seals. Lubricate the O-ring with a compatible fluid or assembly lubricant prior to installation to prevent twisting or tearing during seating. Do not store Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone exposure degrades nitrile elastomers.
