Value Collection ZMSCV70004 Viton O-ring Dash 004 100 Pack

Product Description

The VALUE COLLECTION ZMSCV70004 is a Dash 004 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, refrigeration, and general industrial service. Measuring 0.0781 inches inside diameter and 0.2030 inches outside diameter with a 0.0625-inch (1/16 inch) thickness and a round cross section, this O-ring carries a Shore A hardness of 70. The fluoroelastomer (Viton-type) compound delivers high-temperature resistance up to 400 degrees F and a minimum working temperature of -15 degrees F, making it suitable for demanding service environments. Sold in a package quantity of 100.

This O-ring is used wherever a Dash 004 standard-size seal is required in systems handling petroleum-based fluids, hydraulic oils, fuels, or process gases. Common install scenarios include valve stems, fittings, pump housings, and refrigerant-service components. The low compression set characteristic helps maintain long-term sealing integrity under sustained load. Good vacuum-service performance and low gas permeability make it appropriate for sealed refrigerant or vacuum pump assemblies as well.

Key Features

• Fluoroelastomer (Viton-type) compound with broad chemical compatibility including petroleum products
• Temperature range from -15 degrees F to 400 degrees F
• Shore A hardness of 70 for firm, reliable sealing under compression
• Low compression set for extended service life in static sealing applications
• Low gas permeability suitable for vacuum service and refrigerant-side assemblies
• Round cross section in standard Dash 004 sizing for drop-in replacement fitment

Compatibility

Designed as a standard Dash 004 O-ring replacement compatible with petroleum products and systems requiring fluoroelastomer sealing material. Not FDA approved.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters depending on the application. Always de-energize or depressurize the system and isolate the fluid source before replacing seals. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Verify cross-section groove dimensions match Dash 004 specifications before installation.
