Value Collection ZMSCN70225 Neoprene O-ring Dash 225 50-pack

Product Description

The VALUE COLLECTION ZMSCN70225 is a Dash 225 neoprene O-ring designed to provide reliable sealing in refrigeration, HVAC, and general fluid-handling applications. It features a round cross section, a 1.875-inch inside diameter, a 2.125-inch outside diameter, and a 0.125-inch thickness. Molded to a 70 Shore A hardness rating, this O-ring delivers firm compression set resistance while conforming to mating surfaces under load. The neoprene compound provides moderate resistance to petroleum-based products, good ozone and weather resistance, and is rated for use with refrigerants including Freon-type fluids. Each package contains 50 O-rings.

This O-ring is suited for residential and commercial HVAC, refrigeration, and plumbing applications where a dependable Dash 225-size seal is required. It handles a working temperature range of -65 degrees F to 250 degrees F, making it appropriate for both low-temperature refrigeration circuits and standard hot-water service lines. HVAC technicians, refrigeration mechanics, and plumbers commonly stock this size for field repairs and scheduled maintenance of compressors, service valves, and line fittings that call for a Dash 225 O-ring.

Compatibility

Designed as a standard Dash 225 O-ring replacement for HVAC, refrigeration, and plumbing components requiring a 1.875-inch ID seal with a round neoprene cross section. Compatible with Freon-type refrigerants.

Installation Notes

O-ring installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber depending on the system type. Always recover refrigerant and depressurize the system before replacing seals in refrigeration circuits, and shut off water supply and relieve line pressure before servicing plumbing connections. Lubricate the O-ring lightly with a compatible lubricant before seating to prevent tearing during assembly. Inspect the mating groove for burrs or corrosion before installation to ensure an effective seal.
