Value Collection ZMSCV70269 Viton O-ring Dash 269

Product Description

The VALUE COLLECTION ZMSCV70269 is a Dash 269 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, industrial, and fluid-handling systems. It measures 8.75 inches inside diameter, 9.0 inches outside diameter, and 0.125 inches thick with a round cross section. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring delivers low compression set and high temperature resistance in demanding environments. Hardness is rated at 70 Shore A. Each package contains 2 O-rings. Licensed trades and maintenance professionals working with large-bore sealing applications will find this a dependable fluoroelastomer option for petroleum-compatible service.

This O-ring is suited for use in large-diameter flanged connections, pump housings, valve bonnets, and similar assemblies where resistance to petroleum products and elevated temperatures is required. Its fluoroelastomer compound provides good chemical compatibility across a wide spectrum of fluids, making it a practical choice for HVAC chillers, industrial piping, and pool or water-treatment equipment operating under high-temperature or chemical-exposure conditions. Low gas permeability also qualifies it for vacuum service applications.

Compatible with petroleum products and assemblies requiring fluoroelastomer seals. Designed as a standard Dash 269 O-ring for use in any large-bore groove machined to AS568 Dash 269 dimensions.

Installation Notes

Installation should be performed by a qualified technician familiar with large-bore sealing systems. Depressurize and fully isolate the system before removing the existing O-ring and seating the replacement. Inspect the groove for burrs, scoring, or contamination prior to installation, and apply a compatible lubricant to ease seating without pinching or twisting the ring. Consult applicable codes and equipment manufacturer guidelines for torque and reassembly procedures.
