Value Collection ZMSCVB75237 O-ring Dash 237 Viton 10-pack

Product Description

The VALUE COLLECTION ZMSCVB75237 is a Dash 237 O-ring manufactured from fluoroelastomer (Viton), designed for static and dynamic sealing applications where petroleum resistance and elevated temperatures are concerns. The ring measures 3.375 inches inside diameter, 3.625 inches outside diameter, and 0.125 inches in cross-section thickness, with a round cross-section profile. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring suits demanding environments in HVAC, plumbing, refrigeration, and industrial fluid systems. Licensed trades and maintenance professionals install these as OEM-style replacements or new seals where standard Dash 237 sizing is specified.

This O-ring is appropriate for applications involving petroleum-based fluids, hydraulic oils, fuels, and many chemical media. Its fluoroelastomer construction provides low gas permeability, making it suitable for vacuum service and pressurized systems. Typical install scenarios include pump seals, valve bodies, compressor ports, and pipe fittings in residential and light commercial mechanical systems. The part ships in a package quantity of 10, suitable for service stock or multi-unit jobs.
