Value Collection ZMSCV70142 Viton O-ring Dash 142

Product Description

The VALUE COLLECTION ZMSCV70142 is a Viton (fluoroelastomer) O-ring with a round cross section, sized to Dash 142 standards. It measures 2.375 inches inside diameter, 2.563 inches outside diameter, and 0.0937 inches thick. Rated at 70 Shore A hardness, this O-ring is built for demanding sealing applications where exposure to petroleum products, elevated temperatures, or aggressive chemicals is a concern. The fluoroelastomer compound delivers low compression set and low gas permeability, making it a reliable choice for static and dynamic sealing in HVAC, plumbing, refrigeration, and general mechanical service.

This O-ring is suited for use in residential and commercial applications where a Dash 142 seal is required. Typical install scenarios include pump housings, valve bodies, fluid fittings, and refrigerant or fuel system connections. Its temperature range of -15 degrees F to 400 degrees F makes it appropriate for both high-heat service environments and cold-side applications. Compatibility with petroleum products broadens its use across hydraulic, fuel, and oil-wetted assemblies. This is a package of 10 individual O-rings.

Key Features

• Fluoroelastomer (Viton) compound provides good resistance to petroleum products and wide chemical compatibility
• Temperature rated from -15 degrees F to 400 degrees F for high-heat and cold-side service
• Low compression set maintains seal integrity over extended service cycles
• Low gas permeability makes this suitable for vacuum service applications
• Round cross section conforms to Dash 142 dimensional standards
• 70 Shore A hardness rating — Hard — resists extrusion under pressure

Compatibility

Designed as a standard Dash 142 O-ring replacement compatible with petroleum products and systems requiring fluoroelastomer sealing material in HVAC, plumbing, refrigeration, and general mechanical assemblies.

Installation Notes

Install and service performed by licensed HVAC technicians, plumbers, or qualified mechanics depending on the application. De-energize equipment and relieve all system pressure before replacing any O-ring seal. Inspect the mating groove for damage, debris, or corrosion prior to installation. Do not use petroleum-based lubricants incompatible with fluoroelastomer; confirm lubricant compatibility before assembly.
