Manifold Gauge Set Parts

Our Manifold Gauge Set Parts series provides a complete set of connection and control accessories for charging and testing air conditioning and refrigeration systems. It covers charging hoses, quick-connect charging lines, charging ball valves, can tap valves, quick couplers, and conversion adapters, and pairs flexibly with manifold gauges. It meets the needs of a wide range of refrigerants, from traditional ones such as R12 and R22 to R410A, R32, R1234yf, and R744 (CO₂).

Charging Hose Series (CH-A/CH-B/CH-C/CH-D): Divided into four grades by refrigerant and pressure rating. Grade A is suited to R12/R22/R502, with a working pressure of 500 PSI and a burst pressure of 2500 PSI. Grade B is suited to R22/R134a/R404A/R407C, at 600 PSI/3000 PSI. Grade C is suited to R410A/R32, at 800 PSI/4000 PSI. Grade D uses a four-layer construction and is suited to R1234yf (A2L), at 800 PSI/4000 PSI. Three lengths are offered: 36 in (91cm), 60 in (152cm), and 72 in (182cm), and some models come with a wrench. Connector sizes are available in 1/4 SAE, 5/16 SAE, 1/2 ACME, and M12-1.5, with fitting angles of 180° straight, 45°, and 90°, in red, yellow, blue, or black.

Quick-Connect Charging Lines and Charging Ball Valves: The JF series of quick-connect charging lines includes a self-piercing version (JF-001), a self-sealing version (JF-007), an R1234yf-dedicated version (JF-009, with a 1/2 ACME-LH left-hand thread), and a multi-purpose version covering nine common refrigerants (JF-006B). The WZ-BV charging ball valve fits on one end of a charging hose and closes the line after charging to stop residual refrigerant in the hose from leaking. Thread sizes are selectable, and customization is supported to ISO, UNC/UNF, and NPT standards.

Can Tap Valve Series (CT): All models use a brass valve body, with knob materials including engineering plastic, aluminum alloy, and zinc alloy. Models include R22-dedicated, R134a-dedicated, universal, R22/R134a/R410A general-purpose, R134a (USA) self-piercing, R1234yf (USA) self-sealing, and an R22/R410A version with a retention safety valve. Some models offer explosion-proof and pressure-resistant performance, and backflow prevention is available as an option. The CT-351 weldless piercing valve fits pipes of 6mm, 8mm, and 10mm diameter and creates a charging port without welding.

Quick Coupler Series (QC): Suited to R134a, R1234yf, and R744 refrigerants, mostly with SAE 1/4 in connections. Versions include manual-locking couplers with a knob and push-pull couplers without a knob, offered in straight, 90° elbow, and mini shapes, with a protection cover on some models. The QC-19 and QC-22 comply with the SAE J639 standard, and the QC-22 is dedicated to R744 (G1/4 in connection, operating pressure of 170 bar/2466 psi). Also available are the QC-20 R134a-to-R1234yf conversion kit and the QC-21 extended high-side coupler for BMW, Volvo, and other European vehicles.

Conversion Adapter Series (AD): The AD-M12 and AD-M14 convert 1/4 SAE to M12-1.5 and M14-1.5 metric threads. The AD-10A, AD-30A, and AD-40 convert 1/2 ACME, 5/16 SAE, and 3/8 SAE female ends to a 1/4 SAE male end. The AD-51 and AD-65 convert to R134a and R1234yf ports respectively, and the AD-65 uses a left-hand thread to avoid mix-ups. The whole series supports customization of other thread specifications to ISO, UNC/UNF, and NPT standards.

The whole series is widely used for charging, testing, and repair work on automotive A/C, residential A/C, and commercial refrigeration equipment.
