Value Collection ZMSCVB75031 Viton O-ring Dash 031 25 Pack

Product Description

The VALUE COLLECTION ZMSCVB75031 is a Dash 031 Viton (fluoroelastomer) O-ring used to create static or dynamic fluid seals in hydraulic, pneumatic, and fuel-handling systems. It measures 1.75 inches inside diameter, 1.875 inches outside diameter, and 0.0625 inches thick with a round cross section. The durometer hardness rating is 75 Shore A, placing it in the hard range for reliable compression set resistance. The operating temperature range spans -15 degrees F to 400 degrees F. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this part wherever a chemically resistant, high-temperature seal is required. Each package contains 25 rings.

This O-ring is suited for use in fuel lines, hydraulic circuits, refrigerant-adjacent fittings, and other service environments involving petroleum-based fluids. The fluoroelastomer compound offers broad chemical compatibility and low gas permeability, making it a reliable choice for vacuum service applications as well. It is commonly installed in residential and light commercial HVAC equipment, plumbing assemblies, and industrial fluid-handling hardware where elevated temperatures or petroleum exposure would degrade standard nitrile or EPDM seals.

Key Features

• Fluoroelastomer (Viton) material resists petroleum products, high heat, and a wide spectrum of chemicals
• Operating range of -15 degrees F to 400 degrees F suits high-temperature service environments
• 75 Shore A hardness provides low compression set for long-lasting sealing performance
• Low gas permeability makes this ring suitable for vacuum service applications
• Round cross section, Dash 031 designation for straightforward groove sizing and replacement
• Sold in a 25-piece package to support service inventory and fleet maintenance needs

Compatibility

Designed as a standard Dash 031 O-ring replacement suitable for any groove or fitting specified for a 1.75-inch ID, 1.875-inch OD, 0.0625-inch cross section seal in fluoroelastomer service.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Depressurize and isolate the system completely before removing the worn seal and installing the new ring. Lightly lubricate the O-ring with a compatible grease or fluid before seating it to prevent pinching or tearing during assembly. Inspect the groove for scoring or debris that could compromise the seal before installation.
