Refrigerant Hoses & Fittings

Fittings & Refrigerant Hoses

The Refrigerant Hoses & Fittings category covers the service hoses, couplers and adapters that connect your gauges, recovery machines, vacuum pumps and equipment. The right hose set makes charging faster, vacuum deeper and leak risk lower—while the wrong fittings can slow every job and waste refrigerant.

Here you’ll find standard refrigerant service hoses, vacuum-rated hoses, A2L-compatible hose sets, low-loss and ball-valve hoses, quick-connect couplers, core depressors, flare adapters and service fittings. Options support R-22, R-410A, R-32, R-454B and other common refrigerants used in residential and light-commercial systems.

• Standard and vacuum-rated refrigerant hoses for charging, recovery and evacuation.
• A2L-rated hose sets & fittings matched to newer mildly flammable refrigerants.
• Low-loss and ball-valve hoses to reduce refrigerant release and speed connections.
• Quick-connect couplers & core tools for Schrader valve access and service ports.
• Adapters & flare fittings to match mixed thread types and specialty equipment.

When selecting refrigerant hoses and fittings, check refrigerant compatibility, pressure rating, hose length and diameter, temperature rating, seal material and connection type (¼" or 5/16"). Using vacuum-rated hoses for evacuation and low-loss fittings for charging helps protect the charge, minimize emissions and keep your setup compliant with current regulations.

Pro tip: Keep two dedicated hose kits—one short, large-ID set for vacuum and one standard set for charging. Label each kit and store them separately so oil and debris from old systems don’t migrate into your vacuum rig or new installs.
