Value Collection ZMSCV70049 Viton O-ring Dash 049 2 Pack

Product Description

The VALUE COLLECTION ZMSCV70049 is a Dash 049 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across industrial, HVAC, plumbing, and fluid-handling systems. It measures 5 inches inside diameter, 5.125 inches outside diameter, and 0.0625 inches thick with a round cross section. Made from fluoroelastomer, this O-ring delivers high-temperature resistance up to 400 degrees F, low compression set, and broad chemical compatibility including petroleum-based fluids. Each package contains 2 O-rings. The material also provides low gas permeability, making it suitable for vacuum service applications.

This O-ring is suited for use in residential and commercial systems where sealing against petroleum products, fuels, oils, and high-temperature media is required. Typical applications include pump flanges, valve stems, cylinder heads, and fluid-system fittings. The fluoroelastomer compound performs reliably across a wide temperature range, from -15 degrees F to 400 degrees F, making it appropriate for demanding service environments encountered by HVAC technicians, plumbers, and industrial maintenance professionals.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance professionals. Depressurize and isolate the system completely before removing any existing seals or fittings. Inspect the mating groove for nicks, corrosion, or contamination prior to seating the O-ring. Avoid twisting or stretching the O-ring during installation to prevent premature failure or leakage.
