Value Collection ZMSCA80233 Aflas O-ring Dash 233

Product Description

The VALUE COLLECTION ZMSCA80233 is an Aflas O-ring designed for static and dynamic sealing applications in demanding industrial and mechanical systems. With a 2.875-inch inside diameter, 3.125-inch outside diameter, and a 0.125-inch cross-sectional thickness, this round-profile ring meets Dash 233 dimensional standards. Rated at 80 durometer on the hardness scale, the Aflas compound delivers firm, reliable sealing performance across a working temperature range of 25 to 450 degrees F. The black Aflas construction provides moderate resistance to petroleum products along with good ozone and weather resistance, making it a dependable choice for refrigeration, chemical, and fluid-handling service. Licensed HVAC technicians, plumbers, and industrial mechanics are the primary installers.

This O-ring is well suited for sealing applications involving acetic acid, animal oils, bases, brake fluids, fuels, and hydraulic oil. Its Aflas compound is particularly noted for performance in refrigeration service, including systems that circulate fluorocarbon-based refrigerants. The Dash 233 sizing makes it a standard-dimension replacement in valves, fittings, compressors, and pump housings where this cross-section is specified. It is sold in a package of two rings, making it practical for service kits and bench stock.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics depending on the host system. Always depressurize and de-energize the system completely before disassembling any fitting, valve, or housing to access the O-ring groove. Inspect the groove for scoring or debris before seating the new ring, and apply a compatible lubricant to ease installation and prevent pinching. Follow all applicable system manufacturer guidelines and relevant mechanical codes for the specific service application.
