Value Collection ZMSCVB75020 Viton O-ring Dash 020 50-pack

Product Description

The VALUE COLLECTION ZMSCVB75020 is a Dash 020 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 0.875 inches inside diameter, 1.000 inch outside diameter, and 0.0625 inches thick with a round cross section. The compound carries a Shore A hardness of 75 and is rated for service from -15 degrees F to 400 degrees F, making it suitable for high-temperature and chemically aggressive environments. This SKU is packaged in a quantity of 50 rings, sized for shop stock or service-van inventory. Licensed trades and industrial maintenance personnel are the primary installers.

This O-ring is well suited for use in refrigerant line fittings, hydraulic connections, fuel-system joints, and vacuum service ports where standard Buna-N compounds fall short. The fluoroelastomer material provides broad compatibility with petroleum-based fluids, making it a practical replacement seal in HVAC service valves, plumbing shutoffs, and light industrial equipment. The Dash 020 designation follows AS568 sizing standards, so it drops into any fitting or groove machined to that standard without modification.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or industrial maintenance personnel following applicable trade codes. Depressurize and isolate the system completely before replacing any O-ring seal. Lightly lubricate the ring with a compatible fluid or grease before seating it to prevent tearing during assembly. Inspect the groove for damage or contamination prior to installation and do not reuse a compressed or damaged O-ring.
