Refrigerant Charging Hose

Our refrigerant charging hose series is available in a range of lengths — 36"(91CM), 60"(152CM), and 72"(182CM) — all featuring brass fittings, with select models reinforced with an iron-lined inner layer for added strength at a more economical cost. Working pressure ranges from 500 to 800 PSI, with burst pressure rated up to 4000 PSI, meeting the differing pressure demands of legacy refrigerants (R12, R22, R502), mid-generation refrigerants (R134a, R404A, R407C), and newer high-pressure eco-friendly refrigerants (R410A, R32, and R1234yf with A2L four-layer construction).

Beyond standard charging hoses, we also offer a line of quick-connect charging lines featuring either self-piercing or self-sealing end fittings: the self-piercing version punctures the can for one-time use ideal for fast charging, while the self-sealing version allows repeated connect/disconnect without gas loss — better suited to jobs involving frequent can changes. The dedicated R1234yf version uses a left-hand threaded fitting, physically preventing accidental cross-connection with R134a fittings for added safety. Connector options include 1/4 SAE, 5/16 SAE, 1/2 ACME, and M12-1.5 threads, with fitting angles of 180° straight, 45°, and 90°, and color coding in red, yellow, blue, and black for quick identification of high/low pressure sides or refrigerant type. This series is widely used in automotive A/C servicing as well as vacuuming, diagnostics, and charging work on residential and commercial refrigeration systems.
