Value Collection ZMSCVB75145 Viton O-ring Dash 145

Product Description

The VALUE COLLECTION ZMSCVB75145 is a Dash 145 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where high temperatures and chemical exposure are routine. The ring measures 2.563 inches inside diameter, 2.75 inches outside diameter, and 0.094 inches thick with a round cross section. Shore A hardness is rated at 75, placing it in the hard durometer range. Operating temperature spans -15 degrees F to 400 degrees F, making it suitable for demanding fluid and gas sealing environments encountered in HVAC, plumbing, refrigeration, and industrial systems. Sold in a package quantity of 10.

This O-ring is well suited for use with petroleum-based fluids, hydraulic oils, fuels, and related media. Its fluoroelastomer compound provides low gas permeability, making it appropriate for vacuum service applications. Typical installation scenarios include pump seals, valve stems, fittings, and manifold connections in residential and commercial mechanical systems. The brown color is standard for Viton-compound O-rings and aids in field identification when sorting mixed seal inventories.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or mechanical trades depending on the host system. Always depressurize and de-energize the system before replacing any O-ring seal. Inspect the groove and mating surfaces for scoring or corrosion before seating the new ring. Do not use petroleum-based lubricants that are incompatible with fluoroelastomer compounds; consult the system manufacturer for approved assembly lubricants.
