Value Collection ZMSCV70148 Viton O-ring Dash 148

Product Description

The VALUE COLLECTION ZMSCV70148 is a Dash 148 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where high temperature resistance and chemical compatibility are required. Measuring 2.75 inches inside diameter, 2.938 inches outside diameter, and 0.094 inches thick, this round cross-section ring carries a 70 Shore A durometer hardness rating. Viton compound delivers low compression set, low gas permeability, and broad chemical resistance, making it a reliable choice for sealing fuel, oil, and hydraulic fluid systems. Licensed plumbers, HVAC technicians, and maintenance mechanics regularly specify this material class for demanding service environments.

This O-ring is suited for residential and commercial sealing applications involving petroleum-based fluids, fuels, and high-temperature environments. Typical install scenarios include fuel system fittings, pump housings, valve stems, refrigeration service ports, and hydraulic manifold faces. The fluoroelastomer compound is rated for vacuum service and resists permeation, making it appropriate for low-leak and low-emission assemblies. Each package contains 10 rings, ordered in multiples of 1 package.

Key Features

• Fluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F continuous service
• 70 Shore A hardness with hard hardness rating for controlled compression under clamping load
• Low compression set maintains sealing force over extended service intervals
• Low gas permeability suitable for vacuum service and emissions-sensitive assemblies
• Compatible with petroleum products, fuels, and a wide spectrum of industrial chemicals
• Round cross-section, Dash 148 standard sizing for straightforward groove compatibility

Compatibility

Designed as an OEM-style replacement or service seal for Dash 148 groove profiles in plumbing, HVAC, fuel, hydraulic, and industrial fluid-handling assemblies where fluoroelastomer compound is specified.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off all fluid supply and relieve system pressure completely before replacing any O-ring seal. Lightly lubricate the ring with a compatible fluid or O-ring lubricant before seating it in the groove to prevent rolling or nicking during assembly. Inspect the groove for burrs or scoring that could compromise the seal before installing the new ring.
