Value Collection ZMSCH90118 O-ring Dash 118 Nbr 90 Duro 50-pack

Product Description

The VALUE COLLECTION ZMSCH90118 is a Dash 118 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 0.875 inches inside diameter, 1.063 inches outside diameter, and 0.094 inches thick, with a round cross section. Rated at 90 durometer (extra hard), this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is supplied in a pack of 50 and suits plumbing, HVAC, and general mechanical service where petroleum-based fluid compatibility is required.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, pump seals, valve bodies, and fluid fittings that handle petroleum-based products. The Buna-N compound performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for both refrigeration service and moderate-heat applications. Plumbers, HVAC technicians, and industrial maintenance professionals commonly stock Dash 118 O-rings as a standard replacement seal in residential and light commercial equipment.

• Operating temperature range: -40 degrees F to 250 degrees F
• Round cross section, Dash 118 designation per SAE and MIL-Spec standards
• Strong tear and abrasion resistance for long service life in dynamic or static seals
• Pack of 50 units — suitable for stocking or multi-unit service calls

Compatibility

Compatible with petroleum-based fluids and products. Meets SAE and MIL-Spec standards for Dash 118 O-ring dimensions. Not FDA approved; not intended for food-grade or potable-water applications. Store away from direct sunlight, motors, and electrical equipment that may generate ozone.

Installation Notes

Shut off fluid supply and relieve system pressure before replacing any O-ring seal. Inspect the seating groove for damage, debris, or corrosion before installation. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant to ease seating and reduce the risk of tearing during installation. Follow applicable plumbing or mechanical codes for the system being serviced.
