Value Collection ZMSCH90024 O-ring Dash 024 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90024 is a Dash 024 Nitrile Butadiene Rubber (Buna-N) O-ring sold in a pack of 100. It measures 1.125 inches inside diameter, 1.25 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated at 90 durometer (extra hard hardness rating), this O-ring handles a working temperature range of -40 degrees F to 250 degrees F. It delivers excellent resistance to petroleum products along with strong compression set, tear resistance, and abrasion resistance. Plumbers, HVAC technicians, and mechanical tradespeople rely on Buna-N O-rings as the most widely used elastomer seals in fluid and gas system maintenance.

This O-ring is suited for sealing applications involving petroleum-based fluids, hydraulic oils, fuels, and lubricants in residential and commercial mechanical systems. The Dash 024 sizing is a standard AS568 dimension used across a broad range of fittings, valves, pumps, and hydraulic components. The 90 durometer rating makes it appropriate for higher-pressure applications where a harder, more extrusion-resistant seal is required. Sold in a quantity of 100 per package, this SKU is practical for service technicians stocking a van or a shop parts inventory.

Compatibility

Compatible with petroleum products including hydraulic oils, fuels, and lubricants. Designed as a standard Dash 024 O-ring replacement for use in fittings, valves, pumps, and hydraulic components where Buna-N elastomer is specified. Not FDA approved. Store away from direct sunlight, motors, and electrical equipment that may generate ozone.

Installation Notes

O-ring replacement is performed by licensed plumbers, HVAC technicians, and hydraulic system technicians. Always depressurize and isolate the system before removing the old seal. Inspect the seating groove for damage or debris before installing the new O-ring. Avoid twisting the O-ring during installation, and use a compatible lubricant approved for the system fluid to reduce installation stress and extend service life.
