Value Collection ZMSCV70322 Viton O-ring Dash 322

Product Description

The VALUE COLLECTION ZMSCV70322 is a Dash 322 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 1.25 inches inside diameter, 1.625 inches outside diameter, and 0.1875 inches thick with a round cross section. The fluoroelastomer compound delivers a Shore hardness of 70, a working temperature range of -15 degrees F to 400 degrees F, low compression set, and low gas permeability. These characteristics make it well suited for high-temperature service and systems that carry petroleum-based fluids, refrigerants, or hydraulic media.

This O-ring fits sealing applications where resistance to petroleum products and broad chemical compatibility are required. Typical uses include pump shafts, valve stems, manifold connections, and refrigerant service ports in residential and commercial systems. The fluoroelastomer construction also makes it appropriate for vacuum service. It ships in a package quantity of 10, allowing technicians to stock spares for recurring service calls.

Key Features

• Fluoroelastomer (Viton-type) material with good resistance to petroleum products and wide chemical compatibility
• Working temperature range of -15 degrees F to 400 degrees F for high-heat service environments
• Shore hardness rating of 70 (Hard) for low compression set under sustained clamping loads
• Low gas permeability and suitable for vacuum service applications
• Round cross section, Dash 322 standard sizing for drop-in replacement in standard O-ring grooves
• Packaged in quantities of 10 for shop stock and field kit replenishment

Compatibility

Designed as a standard Dash 322 O-ring replacement for any gland machined to Dash 322 dimensions, commonly found in HVAC refrigerant fittings, plumbing valves, and petroleum fluid handling equipment. Compatible materials include petroleum products and fluids suited to fluoroelastomer seals.

Installation Notes

O-ring replacement is typically performed by licensed HVAC technicians, plumbers, or qualified mechanics depending on the system. Always depressurize, de-energize, and drain or recover the system fluid before disassembling any sealing joint. Inspect the O-ring groove for nicks, burrs, or corrosion before installation and apply a compatible lubricant to ease seating and prevent roll or twist during assembly. Do not reuse a removed O-ring; install a new seal at every service interval.
