Value Collection ZMSCV70267 Viton O-ring Dash 267

Product Description

The Value Collection ZMSCV70267 is a Dash 267 Viton O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and gas systems. Manufactured from fluoroelastomer, it measures 8.25 inches inside diameter, 8.5 inches outside diameter, and 0.125 inches thick. The material carries a hardness rating of 70 Shore A, which places it in the hard range for elastomeric seals. This O-ring is suited for use in HVAC, plumbing, industrial, and mechanical systems where high-temperature or petroleum-fluid exposure is a factor. Licensed tradespeople and maintenance technicians working on large-bore equipment are the typical installers.

This O-ring is appropriate for residential and commercial applications requiring a large-bore seal. It is rated for service from -15 degrees F to 400 degrees F, making it a practical choice for high-temperature fluid lines, refrigerant-side connections, or petroleum-based fluid systems. The fluoroelastomer compound provides low gas permeability, which makes it suitable for vacuum service. Each package contains 2 O-rings. Minimum order quantity is 1 package.

Key Features

• Fluoroelastomer (Viton) construction offers wide chemical compatibility and resistance to petroleum products
• Rated from -15 degrees F to 400 degrees F for high-temperature service
• Low compression set helps maintain long-term sealing integrity under sustained load
• Low gas permeability makes this O-ring suitable for vacuum service applications
• Round cross section conforms to standard Dash 267 O-ring groove dimensions
• Hardness of 70 Shore A provides firm seating in metal and rigid plastic grooves

Compatibility

Compatible with petroleum products and a wide spectrum of chemical media. Designed as a standard Dash 267 O-ring replacement for any application requiring an 8.25-inch ID fluoroelastomer seal with a 0.125-inch cross section.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. Power down or depressurize the system completely and isolate any fluid supply before removing the existing seal. Clean the groove thoroughly and inspect for scoring or corrosion before seating the new O-ring. Do not use petroleum-based lubricants unless confirmed compatible with the system fluid; use an appropriate O-ring lubricant approved for fluoroelastomer seals.
