Value Collection ZMSCV70352 Viton O-ring Dash 352 2 Pack

Product Description

The VALUE COLLECTION ZMSCV70352 is a Dash 352 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid, gas, and vacuum service environments. Measuring 4.875 inches inside diameter and 5.25 inches outside diameter with a 0.1875-inch cross section, this round-profile ring delivers a reliable compression seal in assemblies where chemical resistance and high-temperature stability are required. Rated to 400 degrees F maximum and down to -15 degrees F minimum, it is suited for demanding industrial, HVAC, and plumbing sealing tasks. Each package contains 2 O-rings. Hardness is rated at 70 Shore A.

This O-ring is appropriate for use in residential and commercial systems where sealing against petroleum-based fluids, hydraulic media, or high-temperature gases is required. Typical install scenarios include pump housings, valve bodies, refrigerant-side fittings, and industrial fluid connections. Its fluoroelastomer compound provides low gas permeability, making it a practical choice for vacuum service and pressurized line fittings handled by licensed HVAC technicians, plumbers, and industrial mechanics.

Compatibility

Compatible with petroleum-based products and a wide spectrum of chemical media as noted by the manufacturer. Designed as an OEM-style replacement or service O-ring for assemblies requiring a Dash 352 fluoroelastomer seal.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or industrial mechanics depending on the application. Always depressurize and drain the system or line before removing or replacing any O-ring. Inspect the groove and mating surfaces for scoring or debris before seating the new ring. Do not use petroleum-based lubricants on fluoroelastomer O-rings unless confirmed compatible with the system fluid.
