Value Collection ZMSCV70040 Viton O-ring Dash 040

Product Description

The VALUE COLLECTION ZMSCV70040 is a Dash 040 Viton fluoroelastomer O-ring used to create a reliable fluid or gas-tight seal in mechanical assemblies across HVAC, plumbing, and industrial service applications. It measures 2.875 inches inside diameter, 3.0 inches outside diameter, and 0.0625 inches thick with a round cross-section profile. Made from fluoroelastomer at a Shore hardness of 70, this O-ring is rated for service from -15 degrees F to 400 degrees F, making it suitable for high-temperature and petroleum-based fluid environments. Sold in a package quantity of 10, it is installed by HVAC technicians, plumbers, and mechanical contractors.

This O-ring is suited for use in systems handling petroleum products, hydraulic fluids, and other media compatible with fluoroelastomer compounds. Its low compression set and low gas permeability characteristics make it a practical choice for vacuum service and static or dynamic sealing applications in both residential and light commercial mechanical systems. The round cross-section allows it to seat correctly in standard O-ring grooves machined to Dash 040 dimensional specifications.

Installation Notes

O-rings of this type are installed by licensed HVAC technicians, plumbers, or qualified mechanical contractors. Always depressurize and isolate the system before removing any sealing components. Inspect the mating groove and sealing surfaces for damage or contamination before installing the new O-ring. Lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during assembly.
