Value Collection ZMSCV2X20 Viton O-ring 20x24x2 in

Product Description

The VALUE COLLECTION ZMSCV2X20 is a Viton fluoroelastomer O-ring designed for static and dynamic sealing applications where high temperature resistance and broad chemical compatibility are required. The ring measures 20 inches inside diameter, 24 inches outside diameter, and 2 inches thick, with a round cross section. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring suits demanding industrial and mechanical environments where standard rubber seals would degrade. Licensed trades and maintenance professionals specify Viton seals when the application involves petroleum products, solvents, or elevated process temperatures.

This O-ring is well suited for large-bore flanged connections, pump housings, valve bonnets, and industrial piping systems where petroleum-based media or high-heat conditions are present. Its hard durometer rating (75 Shore A) resists extrusion under pressure, making it appropriate for sealing assemblies with tighter groove tolerances. Plumbers, pipefitters, and industrial mechanics typically specify this size for large-diameter mechanical seals in commercial and industrial installations. The black color is standard for fluoroelastomer compounds of this grade.

Key Features

• Fluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F continuous service
• Good resistance to petroleum products, fuels, and a wide spectrum of chemicals
• Low compression set ensures reliable long-term sealing performance
• Low gas permeability makes it suitable for vacuum service applications
• Hard durometer rating (75 Shore A) resists extrusion under pressure
• Round cross section for compatibility with standard O-ring groove profiles

Compatibility

Designed for use with petroleum products and compatible media in large-diameter O-ring groove assemblies requiring fluoroelastomer sealing material. Verify groove dimensions and media compatibility before installation.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical technician familiar with large-bore seal replacement. Depressurize and isolate the system completely before removing the existing seal. Inspect the groove for nicks, corrosion, or debris that could compromise sealing; clean and lubricate the O-ring with a compatible lubricant before seating. Do not overstretch or twist the ring during installation, as deformation affects sealing integrity.
