Value Collection ZMSCH90028 O-ring Dash 028 Nitrile 90D

Product Description

The VALUE COLLECTION ZMSCH90028 is a Dash 028 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in industrial and fluid-handling applications. It measures 1.375 inches inside diameter, 1.5 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 degrees F to 250 degrees F, making it suitable for a broad range of service conditions. Licensed plumbers, HVAC technicians, and industrial maintenance professionals rely on this seal in petroleum-based fluid systems.

This O-ring is suited for residential and commercial plumbing, HVAC, and hydraulic applications where contact with petroleum products is expected. The Buna-N compound provides excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. It is commonly installed in valve bodies, pump housings, fittings, and fluid-line connections. This item is sold in a package quantity of 100 units, with a minimum order quantity of 1, making it practical for both single-service calls and bulk stocking.

Compatibility

Compatible with petroleum-based fluids and oils. Designed as a standard Dash 028 O-ring replacement for use in valves, pumps, fittings, and fluid-handling assemblies where Buna-N material is specified. Not FDA approved; not recommended for food-contact applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians. Always depressurize and de-energize the system before replacing any O-ring seal. Avoid storing Buna-N O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as this degrades the elastomer. Lubricate the O-ring with a compatible fluid prior to installation to prevent rolling or tearing during assembly.
