Value Collection ZMSCV70429 Viton O-ring Dash 429

Product Description

The VALUE COLLECTION ZMSCV70429 is a Dash 429 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in fluid, vacuum, and gas systems. It measures 5 inches inside diameter, 5.5 inches outside diameter, and 0.25 inches thick, with a round cross section and a 70 Shore A durometer hardness rating. The fluoroelastomer compound delivers high temperature resistance, low compression set, and broad chemical compatibility, making it a reliable sealing solution for licensed plumbers, HVAC technicians, and industrial maintenance professionals working with petroleum-based fluids or high-heat service environments.

This O-ring is suited for residential and commercial service applications where exposure to petroleum products, fuels, oils, hydraulic fluids, or elevated temperatures is expected. Its low gas permeability and suitability for vacuum service also make it applicable in refrigeration, pump, and compressor assemblies. Each package contains 2 O-rings. The operating temperature range spans from -15 degrees F to 400 degrees F, covering the majority of HVAC, plumbing, and light industrial service conditions.

• Package includes 2 O-rings per order unit

Compatibility

Designed as an OEM-style replacement or service O-ring for systems requiring a Dash 429 size seal in fluoroelastomer material, including equipment exposed to petroleum products, hydraulic fluids, and high-temperature service conditions.

Installation Notes

Installation should be performed by a qualified technician familiar with the sealing system being serviced. Depressurize and isolate the system before removing the old O-ring and installing the replacement. Inspect the groove for nicks, burrs, or corrosion that could compromise the seal. Apply a compatible lubricant to the O-ring before installation to ease assembly and reduce the risk of pinching or tearing the seal.
