Value Collection ZMSCV70319 Viton O-ring Dash 319 10 Pack

Product Description

The VALUE COLLECTION ZMSCV70319 is a Dash 319 Viton O-ring with a round cross section, designed for sealing applications where resistance to heat and petroleum-based fluids is required. Made from fluoroelastomer, it measures 1.0625 inches inside diameter, 1.438 inches outside diameter, and 0.1875 inches thick. The material carries a hardness rating of 70 Shore A, placing it in the hard category. Each package contains 10 O-rings. Licensed plumbers, HVAC technicians, and hydraulic system technicians routinely specify fluoroelastomer seals for demanding service environments where standard nitrile or EPDM compounds fall short.

This O-ring is suited for use in systems handling petroleum products, fuels, oils, and hydraulic fluids across residential and commercial applications. Its temperature range of -15 degrees F to 400 degrees F makes it appropriate for high-heat service points such as fuel lines, compressor fittings, valve stems, and pump seals. It is also rated for vacuum service and exhibits low gas permeability, making it a practical choice for refrigerant-side and vacuum-hold applications in HVAC and refrigeration work.

Installation Notes

Installation of O-rings should be performed by a qualified plumber, HVAC technician, or mechanical technician after depressurizing and isolating the system per applicable service procedures. Inspect the groove and mating surfaces for burrs or damage before seating the O-ring. Avoid twisting the O-ring during installation, and use only lubricants compatible with fluoroelastomer compounds. Follow all applicable codes including IPC and IFGC requirements for the system type being serviced.
