Value Collection ZMSCH90115 O-ring Dash 115 Nitrile 90D

Product Description

The VALUE COLLECTION ZMSCH90115 is a Dash 115 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 0.688 inches inside diameter, 0.875 inches outside diameter, and 0.094 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 a broad range of service conditions in HVAC, plumbing, and fluid system applications. Licensed tradespeople and maintenance technicians rely on this O-ring where reliable petroleum-fluid sealing is required.

This O-ring is suited for use in residential and commercial systems involving petroleum-based fluids, hydraulic circuits, pneumatic fittings, and general plumbing assemblies. Its Buna-N construction provides excellent resistance to petroleum products, oils, and fuels, making it a standard choice in HVAC refrigerant service valves, compressor fittings, and plumbing shutoff assemblies. It should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone exposure degrades Nitrile rubber over time. Package quantity is 50 pieces per order.

Compatibility

Compatible with petroleum products, oils, and hydraulic fluids. Conforms to Dash 115 sizing per SAE and MIL-Spec standards. Not FDA approved; not recommended for food-contact or strong-solvent applications. Not compatible with ozone-generating environments or prolonged UV exposure.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics. Always depressurize and isolate the system before replacing an O-ring to prevent injury or fluid release. Lubricate the O-ring with a compatible lubricant before seating to reduce the risk of cutting or distorting the seal during assembly. Inspect the mating groove for burrs or damage before installation.
