Value Collection ZMSCV70220 Viton O-ring Dash 220 Pack 50

Product Description

The VALUE COLLECTION ZMSCV70220 is a Dash 220 Viton (fluoroelastomer) O-ring with a round cross section, sized at 1.375 inches inside diameter, 1.625 inches outside diameter, and 0.125 inches thick. Rated at 70 Shore A hardness, it is formulated for use in systems where petroleum-based fluids, high heat, and chemical exposure are everyday concerns. The fluoroelastomer compound delivers low compression set and low gas permeability, making it suitable for both pressure sealing and vacuum service applications. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics commonly specify this O-ring where a standard nitrile compound does not meet temperature or chemical resistance requirements. Each order includes 50 pieces.

This O-ring is well-suited for residential and commercial HVAC refrigeration fittings, plumbing connections, hydraulic circuits, and fuel-handling assemblies where operating temperatures range from -15 degrees F to 400 degrees F. Its wide spectrum of chemical compatibility makes it a go-to replacement seal in equipment that contacts petroleum products, oils, and many aggressive industrial fluids. The round cross section seats cleanly in standard Dash 220 O-ring grooves, requiring no modification to the groove geometry.

Key Features

• Fluoroelastomer (Viton-type) compound resists petroleum products, oils, and a broad range of industrial chemicals
• 70 Shore A hardness rating balances flexibility and compression resistance for reliable sealing
• Operating range of -15 degrees F to 400 degrees F suits high-heat HVAC and industrial applications
• Low gas permeability and good vacuum service performance
• Low compression set maintains sealing force over repeated thermal cycles
• Round cross section fits standard Dash 220 O-ring grooves without groove modification

Compatibility

Designed as a direct-fit replacement for any standard Dash 220 O-ring groove requiring a fluoroelastomer seal with 1.375 inches ID, 1.625 inches OD, and 0.125 inches cross-section thickness. Compatible material service includes petroleum products and fluids consistent with the fluoroelastomer compound rating.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics following system-specific lockout and pressure-relief procedures before breaking any seal. Lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during installation. Inspect the groove for nicks, burrs, or corrosion that could damage the sealing surface. Confirm groove dimensions match the Dash 220 specification before installation.
