Value Collection ZMSCH90210 O-ring Dash 210 Nitrile 50pk

Product Description

The VALUE COLLECTION ZMSCH90210 is a Dash 210 Buna-N (Nitrile Butadiene Rubber) O-ring sold in a package of 50. It measures 0.75 inches inside diameter, 1 inch outside diameter, and 0.125 inches thick, with a round cross-section profile. Rated at 90 durometer (extra hard), this O-ring handles a working temperature range of -40 to 250 degrees F. Buna-N is the most widely used O-ring elastomer in trade applications, prized for its excellent resistance to petroleum-based fluids, strong compression set retention, and solid tear and abrasion resistance. HVAC technicians, plumbers, and fluid system mechanics reach for this material in the majority of hydrocarbon-fluid service situations.

This O-ring is suited for use in systems handling petroleum products, hydraulic fluids, and similar hydrocarbon-based media. It is a standard Dash 210 size, making it a common replacement seal in HVAC refrigerant line fittings, plumbing shut-off valves, hydraulic manifolds, and general industrial fluid connections. The 50-unit package quantity supports service vans and shop stock where multiple repairs are performed routinely. It is not intended for use with ozone-generating environments or exposure to direct sunlight during storage. Note: this compound is not FDA approved and should not be used in food-grade or potable water applications without verifying compliance with applicable codes.

Compatibility

Compatible with petroleum products and hydrocarbon-based fluids. Designed for use in standard Dash 210 O-ring grooves across HVAC, plumbing, hydraulic, and general industrial fluid system applications.

Installation Notes

O-ring installation should be performed by a qualified technician following applicable system lockout and pressure-relief procedures before breaking any fluid connection. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to prevent twisting or tearing during assembly. Do not store Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone exposure degrades the compound over time. Verify the groove dimensions match Dash 210 specifications before installation to ensure proper sealing.
