Value Collection ZMSCN70120 Neoprene O-ring Dash 120 100pk

Product Description

The VALUE COLLECTION ZMSCN70120 is a Dash 120 neoprene O-ring designed for static and dynamic sealing applications in refrigeration, HVAC, and general industrial service. The ring measures 1.0000 inches inside diameter, 1.1880 inches outside diameter, and 0.0937 inches (3/32 inch) thick, with a round cross section and a Shore hardness rating of 70. Neoprene construction provides moderate resistance to petroleum products along with good ozone and weather resistance, making it a reliable choice for sealing refrigeration fluids including Freon-type refrigerants. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this size in refrigerant circuits, water lines, and general fluid-handling assemblies. Sold in a package of 100.

This O-ring is suited for residential and commercial refrigeration systems, HVAC equipment, and plumbing assemblies where a Dash 120 seal is specified. The neoprene compound performs across a wide service temperature range, from -65 degrees F to 250 degrees F, supporting year-round use in both low-temperature refrigerant circuits and moderate-temperature fluid systems. The black round-cross-section profile seats consistently in standard Dash 120 grooves. The pack quantity of 100 makes this practical for service shops and contractors stocking common seal sizes for recurring maintenance work.

Compatibility

Designed as an OEM-style replacement seal for any application requiring a Dash 120 O-ring with a 1.0000-inch inside diameter, 1.1880-inch outside diameter, and 0.0937-inch cross-section thickness. Compatible with Freon-type refrigerants. Not FDA approved; not intended for food-contact applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified plumbers following applicable system lockout and pressure-relief procedures before disturbing any sealed circuit. Inspect the mating groove for nicks or debris before seating the O-ring, and apply a compatible lubricant to ease installation and reduce the risk of pinching or tearing. Avoid twisting the ring during installation; a twisted O-ring will not seal correctly. Follow all applicable refrigerant-handling regulations under EPA Section 608 when working in refrigerant circuits.
