Value Collection ZMSCV70031 Viton O-ring Dash 031 25-pack

Product Description

The VALUE COLLECTION ZMSCV70031 is a Dash 031 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications where heat, petroleum-based fluids, and chemical exposure are present. The ring measures 1.75 inches inside diameter, 1.875 inches outside diameter, and 0.0625 inches thick. At 70 Shore A hardness, it provides a firm seal with low compression set. Each package contains 25 rings. HVAC technicians, plumbers, and fluid-system mechanics rely on this material where standard nitrile seals would degrade under elevated temperatures or aggressive media.

This O-ring is suited for use in petroleum-based fluid circuits, refrigerant-adjacent assemblies, hydraulic connections, and general sealing applications that see sustained high-temperature service. The fluoroelastomer compound handles temperatures from -15 degrees F to 400 degrees F, making it appropriate for both high-temperature service valves and vacuum-service fittings common in HVAC and industrial plumbing work. The round cross section ensures consistent seating in standard O-ring grooves.

Key Features

• Fluoroelastomer (Viton) construction for high-temperature and chemical resistance up to 400 degrees F
• Low compression set maintains sealing force over repeated thermal cycles
• Good resistance to petroleum products including oils, fuels, and hydraulic fluids
• Suitable for vacuum service with low gas permeability
• Wide spectrum of chemical compatibility beyond petroleum-based media
• Sold in a 25-piece package to support stocking and multi-unit service calls

Compatibility

Designed as an OEM-style replacement or service-stock O-ring for Dash 031 groove dimensions in residential and commercial plumbing, HVAC, and fluid-handling systems where fluoroelastomer material is specified.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. De-pressurize and isolate the fluid circuit before removing the old seal. Lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during assembly. Inspect the groove for burrs or damage before installation, as surface defects will cause premature seal failure.
