Value Collection ZMSCV70161 Viton O-ring Dash 161

Product Description

The VALUE COLLECTION ZMSCV70161 is a Dash 161 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in systems that handle petroleum products, fuels, oils, and hydraulic fluids. It measures 5.5 inches inside diameter, 5.688 inches outside diameter, and 0.094 inches thick, with a round cross section and a Shore A hardness of 70. The fluoroelastomer compound provides high temperature resistance up to 400 degrees F and a low minimum working temperature of -15 degrees F. Licensed plumbers, HVAC technicians, and industrial mechanics install this type of seal during pump, valve, and fitting service.

This O-ring is suited for residential and commercial plumbing, HVAC, and industrial fluid-handling equipment where petroleum-based media compatibility is required. The Dash 161 designation is a standard AS568 size, making it a direct fit for grooves engineered to that dash number. Typical applications include pump housings, valve bonnets, filter bowls, and pipe flange faces exposed to oils, fuels, and high operating temperatures. Its low gas permeability also makes it appropriate for vacuum service installations.

Key Features

• Fluoroelastomer (Viton) compound rated for petroleum products, fuels, and hydraulic fluids
• Operating temperature range: -15 degrees F to 400 degrees F
• Shore A hardness of 70 for reliable compression and low compression set
• Round cross section, 0.094 inches thick, conforming to Dash 161 AS568 sizing
• Low gas permeability suitable for vacuum service applications
• Wide chemical compatibility spectrum beyond petroleum-based media

Compatibility

Designed as a standard Dash 161 O-ring replacement for any groove machined to AS568 Dash 161 dimensions in equipment handling petroleum products, fuels, oils, or high-temperature fluids.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or industrial mechanics. Depressurize and drain the system fully before removing the old seal. Inspect the O-ring groove for scoring or contamination before seating the new ring. Lubricate the O-ring with a compatible fluid or assembly lubricant before installation to prevent damage during compression; avoid petroleum-incompatible greases with Viton seals.
