Product Description

The VALUE COLLECTION ZMSCV70336 is a Dash 336 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 2.875 inches inside diameter, 3.25 inches outside diameter, and 0.1875 inches thick. Rated for a working temperature range of -15 degrees F to 400 degrees F, this O-ring delivers low compression set and high-temperature resistance. The fluoroelastomer compound provides broad chemical compatibility and low gas permeability, making it a dependable choice for service professionals working with petroleum-based fluids, refrigerant systems, and vacuum service applications.

This O-ring is suited for residential and commercial applications where reliable sealing under elevated temperatures or exposure to petroleum products is required. Typical installations include pump housings, valve bodies, compressor fittings, and pipe unions in HVAC, refrigeration, and hydraulic systems. The Dash 336 size is a standard designation, simplifying cross-referencing and replacement during routine maintenance or repair work. Sold in packages of 10, this O-ring is appropriate for service technicians stocking consumables for field repairs.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and isolate the system before replacing any O-ring seal, and confirm the seating groove is clean and free of damage before installing the new ring. Avoid using petroleum-based lubricants during installation unless confirmed compatible with the fluid media in service. Follow applicable codes such as ASHRAE, IPC, or equipment manufacturer guidelines for seal replacement procedures.
