Yellow Jacket 20660 Charging Vacuum Hose 60 in 600 Psi

Product Description

The YELLOW JACKET 20660 is a heavy-duty charging and vacuum hose designed for refrigerant system service work in HVAC and refrigeration applications. Built with a 3/8-inch inside diameter and 3/8-inch flare connections on both ends, this 60-inch hose is engineered for faster refrigerant transfer, faster charging on large systems, and pulling a more complete vacuum. It carries a working pressure rating of 600 psi and a burst pressure rating of 3000 psi, making it well-suited for demanding field use. Licensed HVAC technicians and refrigeration service pros rely on this hose for manifold gauge set work and system evacuation tasks.

This hose is appropriate for residential and commercial HVAC and refrigeration service where a full-length, large-bore charging or vacuum hose is needed. The 60-inch length provides adequate reach between service ports and manifold gauge sets in tight equipment installations. The black color designation helps technicians distinguish hose function in a multi-hose manifold setup. Its temperature rating of -22 to 176 degrees F covers the range encountered in typical refrigerant service environments, including low-ambient recovery and high-ambient charging scenarios.

Key Features

• 3/8-inch inside diameter supports faster refrigerant transfer and more complete vacuum pull compared to smaller-bore hoses
• 600 psi working pressure rating with 3000 psi burst pressure for safe, high-pressure service work
• 60-inch overall length provides extended reach for manifold-to-service-port connections
• 10-inch minimum bend radius maintains flow integrity and prevents kinking in confined spaces
• Temperature rated from -22 to 176 degrees F for use across a broad range of service conditions
• Made in USA

Compatibility

Designed as a replacement or supplemental hose for use with standard 3/8-inch flare manifold gauge sets used in refrigerant recovery, evacuation, and charging service on HVAC and refrigeration equipment.

Installation Notes

Installation and use of this hose should be performed by a licensed HVAC technician or certified refrigeration service professional. Always recover refrigerant and relieve system pressure before disconnecting hoses from service ports. Hand-tighten flare fittings and snug with appropriate wrenches — avoid overtightening, which can damage flare seats. Inspect the hose for cracks, swelling, or damaged fittings before each use and replace if any defects are found.
