Value Collection ZMSCV70432 Viton O-ring Dash 432

Product Description

The VALUE COLLECTION ZMSCV70432 is a Dash 432 Viton (fluoroelastomer) O-ring used for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 5.375 inches inside diameter, 5.875 inches outside diameter, and 0.25 inches thick, with a round cross section and a 70-durometer hardness rating. The fluoroelastomer compound delivers high-temperature resistance, low compression set, and broad chemical compatibility, making it a dependable sealing element where standard nitrile or EPDM compounds fall short. Licensed plumbers, HVAC technicians, and industrial maintenance trades are the typical installers.

This O-ring is suited for sealing flanges, valve bonnets, pump housings, and pipe connections in systems that carry petroleum-based fluids, hydraulic oils, fuels, and similar media. Its rated operating range of -15 degrees F to 400 degrees F makes it appropriate for high-temperature service environments. The low gas permeability characteristic also makes it a practical choice for vacuum service applications. Sold in a package of 2 per order.

Compatibility

Designed for use with petroleum products and compatible fluids in systems requiring a Dash 432 fluoroelastomer O-ring with a 5.375-inch inside diameter, 5.875-inch outside diameter, and 0.25-inch cross section thickness.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial maintenance technician. Depressurize and isolate the system completely before removing the old O-ring or seating the new one. Inspect the groove for nicks, burrs, or corrosion that could damage the sealing surface. Apply a compatible lubricant sparingly to ease installation and avoid twisting or spiraling the O-ring during seating.
