Value Collection ZMSCV70282 Viton O-ring Dash 282

Product Description

The VALUE COLLECTION ZMSCV70282 is a Dash 282 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing in demanding fluid and gas service applications. It measures 16 inches inside diameter, 16.25 inches outside diameter, and 0.125 inches thick. The 70 durometer hardness rating places it in the hard category, offering excellent dimensional stability under compression. This O-ring is commonly installed by plumbers, pipefitters, and industrial maintenance technicians working on large-diameter piping, pressure vessels, pumps, and fluid handling equipment.

This O-ring is suited for applications involving petroleum products, hydraulic fluids, and high-temperature service environments. Its fluoroelastomer compound performs across a wide spectrum of chemical exposures and is appropriate for vacuum service where low gas permeability is required. Typical install scenarios include large-bore flange seals, pump housings, and valve bonnets in commercial, industrial, and heavy mechanical systems where temperature extremes or aggressive media are present.

Key Features

• Fluoroelastomer (Viton) compound delivers good resistance to petroleum products and a wide range of chemicals
• Rated for service from -15 degrees F to 400 degrees F continuous operating temperature
• 70 Shore A durometer hardness provides a firm, low-compression-set seal
• Round cross section for consistent seating in standard O-ring grooves
• Low gas permeability makes it suitable for vacuum service applications
• Black color for easy visual identification in field conditions

Compatibility

Designed as a standard Dash 282 O-ring replacement for large-diameter sealing applications involving petroleum products, hydraulic media, and high-temperature fluids. Compatible materials include petroleum-based products and media suited to fluoroelastomer compounds.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified industrial maintenance technicians. De-energize all pressure sources and bleed system pressure fully before removing any existing seal. Inspect the O-ring groove for damage, debris, or corrosion before seating the new ring. Do not use tools with sharp edges that could nick or cut the sealing surface, as surface damage will cause premature seal failure.
