Value Collection ZMSCN70003 Neoprene O-ring Dash 003 100-pack

Product Description

The VALUE COLLECTION ZMSCN70003 is a Dash 003 neoprene O-ring designed for static and dynamic sealing applications in refrigeration, HVAC, and general fluid systems. The ring measures 0.0625 inches inside diameter, 0.1880 inches outside diameter, and 0.0625 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard range for reliable compression set performance. This package contains 100 pieces, making it suitable for service van stock or bench-level repair operations performed by HVAC technicians, refrigeration mechanics, and plumbing trades.

The ZMSCN70003 is suited for sealing refrigeration fluids including Freon-type refrigerants, as well as general-purpose applications requiring moderate resistance to petroleum products. The neoprene compound offers good ozone and weather resistance, making it a dependable choice for both indoor equipment and outdoor-exposed fittings. Typical install scenarios include compressor service ports, refrigerant line fittings, valve stems, and low-pressure fluid connections where a Dash 003 cross-section is specified. This size is among the smallest standard O-ring dash numbers and is commonly used in precision fittings and instrument connections.

Compatibility

Designed as a standard Dash 003 O-ring replacement for refrigeration, HVAC, and fluid system fittings that specify a neoprene compound with 0.0625 inch inside diameter and 0.0625 inch cross-section thickness. Compatible with Freon-type refrigerants as noted by the manufacturer.

Installation Notes

Installation should be performed by a qualified HVAC technician or refrigeration mechanic. Always recover refrigerant and depressurize the system before replacing O-rings on refrigerant-side fittings. Lubricate the O-ring with a compatible refrigeration oil or O-ring lubricant before seating to prevent tearing during assembly. Avoid overstretching the ring during installation, as damage to the cross section will compromise the seal.
