Value Collection ZMSCV70265 Viton O-ring Dash 265

Product Description

The VALUE COLLECTION ZMSCV70265 is a Dash 265 Viton (fluoroelastomer) O-ring used to create reliable static or dynamic seals in fluid and gas systems. Measuring 7.75 inches inside diameter, 8 inches outside diameter, and 0.125 inches thick with a round cross section, this ring seals against petroleum-based fluids, fuels, and a wide range of chemicals. The 70-durometer hardness rating means the ring resists compression set while conforming to mating grooves. Its fluoroelastomer compound handles temperatures from -15 degrees F to 400 degrees F, making it well suited for high-temperature service environments where standard nitrile O-rings fail. Each package contains 2 rings.

This O-ring is used across HVAC, plumbing, pool, and industrial piping applications wherever large-bore sealing is required. Common install scenarios include pump housings, heat exchanger flanges, large valve bodies, and manifold covers that see petroleum-based media or elevated operating temperatures. The round cross section fits standard Dash 265 O-ring grooves per industry gland dimensions. HVAC technicians, plumbers, and mechanical contractors are the typical installers. The fluoroelastomer material is also rated for vacuum service and exhibits low gas permeability, which makes it a practical choice for refrigeration or gas line components that require a chemical-resistant seal.

• Operating range of -15 degrees F to 400 degrees F for high-temperature service
• 70 durometer hardness — hard rating with low compression set for long-term sealing integrity
• Suited for vacuum service with low gas permeability
• Round cross section conforms to standard Dash 265 gland dimensions
• Package contains 2 rings; minimum order quantity is 1 package

Compatibility

Designed as a Dash 265 O-ring replacement for equipment grooves sized for a 7.75-inch ID, 8-inch OD, 0.125-inch cross section seal. Compatible with systems handling petroleum products and other media suited to fluoroelastomer seals.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical contractor. Shut off all fluid supply and relieve system pressure before removing the old O-ring or disassembling the joint. Inspect the gland groove for nicks, burrs, or chemical damage before seating the new ring. Do not use petroleum-based lubricants unless confirmed compatible with fluoroelastomer; use an approved O-ring lubricant to ease installation without cutting or twisting the ring.
