Value Collection ZMSCVB75334 Viton O-ring Dash 334 10-pack

Product Description

The VALUE COLLECTION ZMSCVB75334 is a Dash 334 Viton (fluoroelastomer) O-ring sold in a package of 10. It measures 2.625 inches inside diameter, 3.0 inches outside diameter, and 0.1875 inches thick with a round cross-section. The material is rated at a Shore A hardness of 75 and handles a working temperature range of -15 degrees F to 400 degrees F. Fluoroelastomer construction delivers low compression set, high temperature resistance, and broad chemical compatibility, making this O-ring a reliable sealing choice for demanding fluid and gas service applications. Plumbers, HVAC technicians, and industrial maintenance professionals are the primary installers.

This O-ring is suited for use in systems that handle petroleum products, hydraulic fluids, and similar media where standard nitrile or EPDM compounds would degrade. The fluoroelastomer compound also supports vacuum service and exhibits low gas permeability, making it appropriate for refrigerant-side and fuel-system sealing in both residential and light commercial applications. The brown color is characteristic of standard Viton-family compounds and aids in field identification when sorting mixed seal inventories.

Key Features

• Fluoroelastomer (Viton-type) material with Shore A hardness of 75 for firm, reliable sealing under pressure
• Wide temperature range: -15 degrees F to 400 degrees F continuous service
• Good resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals
• Low compression set maintains seal integrity over extended service intervals
• Low gas permeability makes it suitable for vacuum service and refrigerant-side applications
• Sold in a package of 10, with a minimum order quantity of 1 package

Compatibility

Designed as a standard Dash 334 O-ring replacement for static and dynamic sealing applications in systems handling petroleum products, fuels, and high-temperature fluids where fluoroelastomer compounds are specified. Not FDA approved; not intended for food-contact applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics as part of a fitting, valve, or pump service. Always depressurize and drain the system before replacing O-rings, and confirm the groove dimensions match the Dash 334 cross-section before installation. Lubricate the O-ring with a compatible grease or fluid prior to seating to prevent twisting or pinching. Do not use lubricants that are incompatible with fluoroelastomer compounds.
