Value Collection ZMSCVB75119 Dash 119 Viton O-ring 50-pack

Product Description

The VALUE COLLECTION ZMSCVB75119 is a Dash 119 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where elevated temperatures and chemical exposure are a concern. Measuring 0.938 inches inside diameter, 1.125 inches outside diameter, and 0.103 inches thick with a round cross section, this O-ring carries a Shore A hardness rating of 75. The fluoroelastomer compound delivers a working temperature range of -15 to 400 degrees F, low compression set, and low gas permeability. Each package contains 50 O-rings. HVAC technicians, plumbers, and industrial maintenance professionals specify this material when standard nitrile or EPDM compounds fall short on heat or chemical resistance.

The ZMSCVB75119 is suited for sealing applications involving petroleum products, hydraulic fluids, fuels, and a wide spectrum of industrial chemicals. It is commonly used in HVAC refrigerant-side fittings, compressor housings, valve stems, pumps, and fluid-handling equipment operating at elevated temperatures. The brown color is characteristic of standard fluoroelastomer (Viton-type) compounds and aids visual identification during service. This O-ring is not FDA approved and should not be specified for food-contact or pharmaceutical applications.

Compatibility

Compatible with petroleum products and a wide spectrum of industrial chemicals and fluids. Designed as a Dash 119 standard-size O-ring for use in any groove or fitting machined to the AS568 Dash 119 cross-section specification.

Installation Notes

Installation of O-rings should be performed by qualified HVAC technicians, plumbers, or mechanical maintenance personnel following equipment manufacturer procedures. Always depressurize and isolate the system before removing or replacing seals. Lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during assembly. Inspect the groove and mating surfaces for nicks or burrs that could compromise the seal.
