Value Collection ZMSCV70169 Viton O-ring Dash 169

Product Description

The VALUE COLLECTION ZMSCV70169 is a Dash 169 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications in systems that handle petroleum products, fuels, and hydraulic fluids. With a 7.5-inch inside diameter, a 7.688-inch outside diameter, and a 0.094-inch round cross section, this O-ring is built for larger bore fittings and flanges. The fluoroelastomer compound delivers a hardness of 70 Shore A, providing low compression set and reliable sealing across a wide range of chemical exposures. Sold in packages of 2.

This O-ring is suited for HVAC, plumbing, hydraulic, and industrial fluid-handling applications where petroleum product resistance and high-temperature performance are required. It is appropriate for both vacuum service and pressurized systems. The broad chemical compatibility and low gas permeability make it a dependable choice for refrigerant-adjacent, fuel, and oil system sealing in residential and commercial installations. Licensed technicians and pipefitters typically source Dash 169 O-rings for larger valve bodies, manifold flanges, and pump housings.

Key Features

• Fluoroelastomer (Viton) material with 70 Shore A hardness for firm, reliable sealing
• Operating temperature range of -15 degrees F to 400 degrees F
• Good resistance to petroleum products, fuels, and hydraulic fluids
• Low compression set for long-term sealing integrity under sustained load
• Low gas permeability — suitable for vacuum service applications
• Round cross section for standard O-ring groove compatibility

Compatibility

Designed as an OEM-style replacement or service O-ring for systems requiring a Dash 169 fluoroelastomer seal with a 7.5-inch inside diameter. Compatible materials include petroleum products and related fluids as stated by the manufacturer.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. Depressurize and isolate the system completely before removing the existing O-ring. Inspect the groove and mating surfaces for nicks or corrosion before seating the new O-ring. Use only a lubricant compatible with fluoroelastomer and the system fluid — do not use petroleum-based grease on O-rings unless confirmed compatible with the media being sealed.
