Value Collection ZMSCV70219 Viton O-ring Dash 219 50-pack

Product Description

The VALUE COLLECTION ZMSCV70219 is a Dash 219 Viton (fluoroelastomer) O-ring used to create reliable static or dynamic seals in fluid and gas systems. With a 1.313-inch inside diameter, 1.563-inch outside diameter, and 0.125-inch cross section, this round-profile ring is sized to the Dash 219 standard. Rated for continuous service from -15 degrees F to 400 degrees F, it handles elevated temperatures that would degrade standard nitrile or EPDM compounds. Shore A hardness of 70 provides firm sealing pressure under compression. Each package contains 50 rings. HVAC technicians, plumbers, and industrial maintenance professionals install this part where high-temperature or chemical-exposure conditions demand a fluoroelastomer seal.

This O-ring is suited for petroleum-based fluid systems, hydraulic assemblies, fuel handling equipment, refrigeration service connections, and vacuum systems where low gas permeability is a requirement. Its wide chemical compatibility makes it a common choice in commercial HVAC equipment, industrial process piping, and pump or valve assemblies that operate under elevated temperature cycles or prolonged exposure to oils and fuels. The 50-piece package quantity supports service truck stock and shop inventory alike.

Compatibility

Compatible with petroleum products and a wide spectrum of chemical media. Designed as a standard Dash 219 fluoroelastomer O-ring for use in any system or fitting groove machined to Dash 219 dimensions.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or industrial mechanics as part of valve, fitting, pump, or manifold service. Always depressurize and isolate the system before replacing O-rings, and verify the groove dimensions match the Dash 219 cross section before installation. Lightly lubricate the O-ring with a compatible fluid or grease to prevent tearing during assembly — do not use petroleum-based lubricants on compounds that are not petroleum-compatible, though Viton is rated for petroleum service. Inspect the groove for nicks or burrs that could damage the sealing surface.
