Value Collection ZMSCV70170 Viton O-ring Dash 170

Product Description

The VALUE COLLECTION ZMSCV70170 is a Dash 170 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid and gas systems. With a 7.75-inch inside diameter, a 7.938-inch outside diameter, and a 0.094-inch round cross section, this O-ring seats into standard Dash 170 grooves. The fluoroelastomer compound delivers hard-rated 70 Shore A durometer hardness, low compression set, and high resistance to elevated temperatures up to 400 degrees F. Licensed HVAC technicians, plumbers, and industrial mechanics specify this material for petroleum-based fluid environments where standard nitrile compounds fall short.

This O-ring is suited for use in hydraulic systems, fuel-handling assemblies, pump housings, valve bodies, and compressor service applications where contact with petroleum products, oils, or high operating temperatures is expected. Its fluoroelastomer construction also supports vacuum service and resists gas permeability, making it a reliable choice for refrigerant-side repairs and low-pressure pneumatic fittings. The -15 degrees F minimum working temperature makes it appropriate for most indoor mechanical room and rooftop equipment environments. Sold in a package of two.

Key Features

• Fluoroelastomer (Viton-type) material rated for petroleum product compatibility
• Operating temperature range: -15 degrees F to 400 degrees F
• 70 Shore A hardness with hard-rated compression resistance and low compression set
• Round cross section conforms to standard Dash 170 groove dimensions
• Suitable for vacuum service and low gas permeability applications
• Wide spectrum of chemical compatibility beyond petroleum-based fluids

Compatibility

Designed as a standard Dash 170 O-ring replacement for any application requiring a 7.75-inch ID fluoroelastomer seal in petroleum-compatible fluid or gas systems.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing system service. Depressurize and drain the system fully before removing the old O-ring. Inspect the groove for scoring or corrosion prior to seating the new ring. Lubricate with a compatible fluoroelastomer-safe compound only — do not use petroleum-based grease on fluoroelastomer seals unless confirmed compatible with system fluids.
