Value Collection ZMSCV70334 Viton O-ring Dash 334 10-pack

Product Description

The VALUE COLLECTION ZMSCV70334 is a Dash 334 Viton (fluoroelastomer) O-ring with a round cross section, rated for static and dynamic sealing applications where petroleum-based fluid exposure and elevated temperatures are a concern. The inside diameter measures 2.625 inches, outside diameter measures 3.0 inches, and wall thickness is 0.1875 inches. Hardness is rated at 70 Shore A, placing it in the hard durometer range. This package contains 10 O-rings. Installation is performed by qualified plumbers, pipefitters, HVAC technicians, and industrial maintenance mechanics working on fluid and gas handling systems.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel-handling circuits, chemical processing lines, and HVAC refrigerant or fluid circuits where high-temperature and chemical resistance are required. The fluoroelastomer compound performs reliably in environments with petroleum products, making it a common choice for pump seals, valve stems, flanged connections, and fittings operating at elevated temperatures or under vacuum conditions. Residential and commercial applications are both within scope depending on the system configuration.

Key Features

• Fluoroelastomer (Viton) compound provides good resistance to petroleum products and fuels
• Operating temperature range of -15 degrees F to 400 degrees F for broad thermal coverage
• Low compression set reduces the risk of seal failure over extended service cycles
• Low gas permeability and suitability for vacuum service applications
• Wide spectrum of chemical compatibility for use across multiple fluid types
• Round cross section, Dash 334 standard sizing for straightforward groove fitment

Compatibility

Designed as a standard Dash 334 replacement O-ring compatible with grooves and fittings dimensioned to accept a 2.625-inch ID by 3.0-inch OD by 0.1875-inch cross section seal in systems handling petroleum products, fuels, or high-temperature process fluids.

Installation Notes

Depressurize and lock out the system before removing any existing seals or fittings. Inspect the O-ring groove for scoring, corrosion, or debris before installing the new ring; a damaged groove will cause premature seal failure. Apply a compatible lubricant to the O-ring to ease installation and prevent twisting or rolling during assembly. Ensure the O-ring seats fully and evenly in the groove before reassembling the joint and returning the system to service.
