Other Tools

Our Other Tools series is designed around testing, maintenance, and auxiliary work in refrigeration, air conditioning, and automotive repair. It covers A/C leak detection, coolant and fuel system testing, engine cylinder testing, refrigerant recovery, oil filling and fluid management, system flushing and cleaning, and system maintenance accessories such as sight glasses, valve core tools, and manual valves, giving automotive A/C, residential A/C, and commercial refrigeration equipment a matching toolset from diagnosis through maintenance.

A/C Leak Test Kit Series (WZ-LT): Offered in configurations from portable quick versions up to the 123-piece complete kit, covering the A/C systems of passenger cars, trucks, excavators, and agricultural vehicles. The 123-piece complete kit includes universal adapters, dedicated plugs, and a test tracer; the 108-piece special edition focuses on European and US vehicles; the 81-piece professional kit balances completeness and cost; the 20-piece portable kit suits on-site and mobile service; the 17-piece multi-function kit is optimized for Asian vehicles; and the 13-piece precision diagnostic kit includes pressure-holding test components for locating tiny leaks. Color-coded adapters make parts quick to identify and match.

Pressure and Engine Testing Series (WZ-CP/WZ-EFP/WZ-FP): The coolant pressure test kit comes in 18-, 28-, 31-, and 34-piece versions, made of aluminum alloy, nylon, and brass, with color-coded adapters and a portable storage case. The fuel pump pressure recheck kit includes a differential pressure gauge, metal adapters, a 9V battery, and a carrying bag, suited to technical arbitration and warranty appraisal. Engine cylinder testing is offered as a 13-piece basic kit, alongside a cylinder leak detection kit that quantifies sealing condition through pressure-holding tests, and 4-piece and 20-piece portable versions for on-site testing.

Refrigerant Recovery Series (WZ-RM): Uses an oil-less, air-cooled piston compressor with an automatic purge function, low-pressure protection that stops the machine automatically, and a high-pressure cutoff device, and can recover both refrigerant vapor and liquid refrigerant. The WZ-RM03 uses brushless DC motor technology at 1 HP and 3000 RPM and supports new refrigerants such as R32 and R1234yf; the RM02 Intelligent Control series adds R32 and R1234yf compatibility to the RM01 series.

Fluid Management and Cleaning Series (WZ-OF/WZ-FO/WZ-FP04/WZ-TF/WZ-FC/WZ-FB): Manual and pneumatic oil injectors come in two capacities, 1/4 oz (7.5 ml) and 2 oz (60 ml), with backflow protection and support for injecting leak detection dye and color-change agents. Engine oil funnel kits are available in 10-piece and 23-piece configurations, plus a 4-piece foldable version. The transfer pump tool is suited to changing brake fluid, transmission oil, and transmission fluid, and includes a 1-liter old brake fluid collector. The fuel nozzle cleaning kit and the A/C flush kit are used for cleaning carbon deposits from nozzles and for deep cleaning of A/C systems respectively. PAG46 lubricant is tested by infrared spectrometer and is compatible with both R134a and R1234yf refrigerants.

System Testing and Maintenance Accessories: The sight glass lets users watch refrigerant flow directly and shows moisture content through a color change, in sizes from 1/4 in to 3/4 in. The valve core removal tool is used to replace and maintain valve cores and has a built-in metal ball valve switch. The KM series manual valve has a diaphragm structure suited to one-way flow and can control liquid, suction media, and hot gas lines. The refrigerant leak detection product suits R134a and R1234yf systems, with one syringe per vehicle. Some products are made with European original manufacturing craftsmanship.

The whole series is widely used at automotive repair shops and for testing, maintenance, and servicing of residential and commercial refrigeration equipment, from portable quick-repair tools to professional testing equipment, meeting the needs of repair businesses of different sizes.
