Value Collection ZMSCV70144 Viton O-ring Dash 144

Product Description

The VALUE COLLECTION ZMSCV70144 is a Viton (fluoroelastomer) O-ring sized to Dash 144 with a 2.5-inch inside diameter, 2.688-inch outside diameter, and 0.0937-inch cross-section thickness. It features a round cross-section profile and a Shore A hardness rating of 70. Viton compound provides strong resistance to petroleum-based fluids, high operating temperatures up to 400 degrees F, low compression set, and low gas permeability. Licensed HVAC technicians, plumbers, and industrial maintenance professionals use this O-ring as a static or dynamic seal in fluid and gas handling assemblies where chemical and thermal resistance are required.

This O-ring is suited for residential and commercial applications involving petroleum products, hydraulic fluids, fuels, and high-temperature service environments. Typical install scenarios include sealing pump housings, valve bodies, fittings, and refrigeration or HVAC service ports where standard nitrile seals lack adequate chemical or temperature compatibility. The wide chemical compatibility of the fluoroelastomer compound also makes it appropriate for vacuum service applications and assemblies requiring low gas permeability. Sold in a package quantity of 10 with a minimum order quantity of 1.

Key Features

• Fluoroelastomer (Viton) compound rated for service from -15 degrees F to 400 degrees F
• Shore A hardness of 70 for firm sealing under compression
• Good resistance to petroleum products, fuels, and hydraulic fluids
• Low compression set supports long-term sealing performance
• Low gas permeability makes it suitable for vacuum service
• Round cross-section profile for standard O-ring groove fitment

Compatibility

Designed as an OEM-style replacement or service O-ring for fluid and gas system components requiring a Dash 144 fluoroelastomer seal, including applications with petroleum products and high-temperature media. Not FDA approved.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Always depressurize and isolate the system before replacing any O-ring seal. Inspect the groove for nicks, burrs, or contamination before seating the new O-ring. Use a compatible lubricant approved for fluoroelastomer compounds and the specific media being sealed; avoid petroleum-based lubricants in systems where cross-contamination is a concern.
