Value Collection ZMSCVB75146 O-ring Dash 146 Viton

Product Description

The VALUE COLLECTION ZMSCVB75146 is a Dash 146 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and industrial systems. It measures 2.625 inches inside diameter, 2.813 inches outside diameter, and 0.094 inches thick with a round cross section. The fluoroelastomer compound delivers a Shore A hardness of 75, a working temperature range of -15 to 400 degrees F, and low gas permeability suited to vacuum service. Licensed tradespeople and maintenance technicians install these rings wherever a reliable, chemical-resistant seal is required in petroleum-product environments.

This O-ring is appropriate for residential and commercial service applications involving petroleum-based fluids, hydraulic oils, fuels, and select chemical media. Its wide spectrum of chemical compatibility makes it a common choice in HVAC refrigerant circuit fittings, fuel-system connections, and industrial fluid-handling assemblies. Each package contains 10 rings, and the minimum order quantity is 1 package. The brown color provides quick visual confirmation of fluoroelastomer material on the bench or in the field.

Compatibility

Designed as an OEM-style replacement Dash 146 O-ring for sealing applications requiring a 2.625-inch inside diameter fluoroelastomer ring compatible with petroleum products and high-temperature service environments.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance mechanics depending on the host system. Always depressurize and isolate the system before removing the old ring and seating the replacement. Inspect the gland groove for nicks, burrs, or debris before installation, and apply a thin film of compatible lubricant to seat the ring without twisting or rolling. Follow applicable system codes such as NEC, IPC, or equipment manufacturer guidelines as appropriate to the installation context.
