Value Collection ZMSCV70167 Viton O-ring Dash 167 2-pack

Product Description

The VALUE COLLECTION ZMSCV70167 is a Dash 167 Viton fluoroelastomer O-ring used to create reliable static or dynamic seals in fluid and gas handling systems. It measures 7 inches inside diameter, 7.188 inches outside diameter, and 0.0937 inches thick with a round cross section. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is well suited for applications involving petroleum products, high heat, and vacuum service. Each package contains 2 O-rings. Licensed HVAC techs, plumbers, and industrial mechanics commonly install this part during equipment rebuilds, valve service, and pump maintenance.

This O-ring is appropriate for residential and commercial applications where sealing against petroleum-based fluids, fuels, or hydraulic media is required. Its fluoroelastomer compound offers low compression set and low gas permeability, making it a reliable choice in HVAC equipment, fuel-handling assemblies, compressors, and pump housings. The 70-durometer hardness rating provides a firm seal under moderate to high clamping loads without excessive cold flow.

Key Features

• Fluoroelastomer (Viton) material provides good resistance to petroleum products and wide chemical compatibility
• Operating temperature range of -15 degrees F to 400 degrees F suits high-heat service environments
• Low compression set helps maintain sealing force over extended service cycles
• Low gas permeability and good vacuum service performance
• 70-durometer hardness rated Hard for firm sealing under load
• Round cross section, Dash 167 standard sizing for consistent fit in standard O-ring grooves

Compatibility

Designed as a standard Dash 167 O-ring replacement for any application requiring a 7-inch ID fluoroelastomer seal compatible with petroleum products and high-temperature service.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. Always depressurize and de-energize the system and relieve any residual fluid pressure before removing the existing O-ring. Clean the groove thoroughly and inspect for damage before seating the new O-ring. Avoid twisting or rolling the O-ring during installation, and do not use sharp tools that could nick the sealing surface.
