Service couplers
Service couplers connect your service equipment, hoses or charging station to the service ports of an air conditioning system. This category covers manual quick couplers for both the high-pressure side (HP) and the low-pressure side (LP), with and without an integrated tap. The coupler clicks onto the system's service port and connects on the other end to a 1/4" SAE hose or station. Versions with a tap let you open and close the flow while connecting and disconnecting, so no refrigerant is lost. High-pressure and low-pressure couplers are not interchangeable; always check which side and which refrigerant (R134a or R1234yf) your system uses.

Detection equipment
Equipment and tools to find leaks in air conditioning systems. This category covers electronic leak detectors, hydrogen/forming gas detectors, UV lamps, UV leak detection dye and injectors used to trace the source of refrigerant loss. Leak detection is a standard part of air conditioning service: a system that loses refrigerant cools poorly and must be leak-free before it is recharged. Depending on the method, you trace leaks with an electronic detector, with forming gas (hydrogen-nitrogen) or with UV dye combined with a UV lamp. Always check which method and which refrigerant suit your equipment and system.

A/C service stations
Select an A/C service unit based on the refrigerant used in your workshop. Modern cars use R1234yf, older ones R134a. A machine that handles both gives you flexibility. Tank capacity and pump speed determine cycle time. Ensure the unit evacuates, recycles and recharges automatically. Some units only recover refrigerant, they cannot recharge. You need a full service unit for complete maintenance.

Work gloves & goggles
You have to choose between two types of work gloves here. One type resists coolant and oil, while the other gives you grip for heavy mechanical tasks. Getting the size right is important, because a loose glove reduces the feel in your fingertips. For goggles, pick a version that fits over your own glasses. That seal keeps splashes and dust out of your eyes during the job.

Service unit spare parts
You buy service unit spare parts for AC machines. Check the thread pitch and coupling before ordering. 1/2 inch ACME is standard for recovery units, but 1/4 inch flare is also used. Ensure the part works with R134a or R1234yf. A wrong filter or seal causes leaks and downtime. Order hoses and valves that fit your exact unit model.

Refrigerant & cylinders
Your A/C machine runs on the correct refrigerant. Never mix R134a and R1234yf because that destroys the compressor. Choose the cylinder by weight and type, and check the valve fitting on your recovery tank. Order the right gas for every repair.

A/C cleaning
Clean the vehicle's A/C system with foam or spray. Foam expands and removes bacteria from the evaporator core. Sprays only reach exposed surfaces. Choose foam when odours persist. Use a lance for the deep core. Check the drain hose for blockages first. Make sure the cleaner fits aluminium.

Measuring tools
This range holds measuring tools you use daily in the workshop. Pick a 150 mm caliper for brake discs and wheel bearings. Digital versions show readings on a display, analogue ones need no battery. Choose stainless steel for durability and a finish that resists workshop dirt. For digital models, the common battery type is LR44. Store instruments in a case to keep them dry and dust-free. Accurate work starts with a reliable measurement, so select the version that matches your measuring frequency.

Service sets
First, determine what refrigerant you work with. R134a and R1234yf have different quick couplings. The wrong choice gives leaks. These sets contain gauges, hoses, and connectors. You use them to measure pressure and recharge. A set with a vacuum pump handles a full recovery and refill. Check the connection size of your existing equipment before ordering.

Answers to the most common questions from our customers
Note the make and model of your charging or recovery station and look at the connection the station needs. Compare that with the top and bottom connection of the adapter, for example M1/4" SAE male on top and M1/8" NPT male underneath. An R-1234yf station asks for different couplings than an R-134a station. Also measure the old adapter, so you know the sizes are right.
A refillable oil bottle you fill yourself with oil from a larger pack, a cartridge replacement goes into the service station in place of the original cartridge. Check on your station which connection the oil line has and whether a cartridge or a bottle goes in. There is also a conversion kit to move from cartridge to bottle. Order the bottle and the oil as two separate lines.
For modern A/C systems with R-1234yf and for hybrid and electric vehicles POE oil is used, for R-134a systems PAG oil. Which of the two you need is in the vehicle data or on the system itself. Never just use the oil that is still on the shelf, because the wrong oil can damage the compressor. The oil and additives are under Oil & additives.
There are two routes. UV leak detection additive goes into the system and belongs with the UV lamp and the protective UV glasses. The electronic hydrogen leak detector is a portable unit you carry along pipes and couplings. Check which method your workshop already uses, so you are not working with two systems side by side. Both are under Detection equipment.
PED 2014/68/EU is the directive for pressure equipment and applies to cylinders with refrigerant under pressure. On the cylinder it states which category it falls under, for example art. 4 par. 3. When you order, watch the connection your service station expects, because R-134a and R-1234yf have different couplings. Keep those two apart on the shelf and use the right cylinder adapter.
A/C service: choose by connection and machine
Which connection do you need
With an adapter or service coupling you look first at the two ends of the part. The top is for example M1/4" SAE male with a conical flare, the bottom M1/8" NPT male with a tapered pipe thread. An R-134a high pressure quick coupling carries the marking HP, a low pressure quick coupling LP. Write both ends down before you order, because an adapter with the right top and the wrong bottom will not fit. In Adapters Adapters the versions sit side by side, with the connection of each one in the specifications.
For which service station
Adapters and service couplings are made for A/C charging and recovery stations from Robinair, Ecotechnics, Air Solutions, Oksys, Texa, Brain Bee, Mahle and Bosch, among others. Give the make and model of your station when you search, and the choice stays limited to the versions that fit it. For R-1234yf systems there are separate couplings, which do not belong on an R-134a station. The service couplings themselves are in Service couplers Service couplings.
Changing oil: bottle or cartridge
When you change compressor oil you work with a refillable oil bottle or with a cartridge replacement. The bottles come in several capacities, including 250 ml, and there is a conversion kit to move from cartridge to bottle. Check on your service station which connection the oil line has and whether a cartridge or a bottle goes in. The oil itself, PAG and POE, is under Oil & Additives Oil & additives. Order the bottle and the oil as two separate lines.
Leak detection: additive or detector
There are two routes for tracing a leak. UV leak detection additive goes into the system and belongs with the UV lamp and the protective UV glasses. The electronic hydrogen leak detector is a portable unit you carry along pipes and couplings. Both are in Detection equipment Detection equipment, together with the matching glasses and lamps. Before you order, check which method your workshop already uses, so you are not working with two systems side by side.
Filters and hoses
Filters and filter driers belong to the service interval and take up moisture in the circuit. Hoses and accessories come in various diameters and lengths, with connections for the most used charging and recovery stations. Measure the old hose or filter before you order.
Refrigerant and cylinders
Refrigerant and cylinders sit apart, with the cylinder adapters that connect 1/4" SAE service equipment to a refrigerant cylinder. Watch the PED 2014/68/EU marking on the cylinder and the connection your station expects. R-134a and R-1234yf have different couplings, so keep those two apart on the shelf. The cylinders and accessories are in Refrigerant & cylinders Refrigerant & cylinders.
