Car AC Quick Couplers, R134a or R1234yf Options

Connect matching service equipment to a vehicle's air-conditioning ports during workshop checks. These quick couplers come in R134a and R1234yf options, including adjustable versions. They are for trained automotive air-conditioning technicians selecting fittings for an existing service setup.

Select the couplers for your AC service system

• ✅ Match the vehicle before connecting. Choose the R134a or R1234yf option that corresponds to the air-conditioning service ports.
• ✅ Distinguish the service sides. Red and blue identification separates the high-pressure and low-pressure couplers during setup.
• ✅ Control the adjustable connection. Top-mounted knobs on adjustable versions provide manual opening and closing.
• ✅ Add fittings to existing equipment. The couplers connect service ports and compatible hoses without replacing your whole manifold setup.

Start with the refrigerant system and hose connections used by your equipment. R134a and R1234yf are separate selections; a fitting for one should not be assumed to fit the other.

The R134a range includes adjustable, non-adjustable and All-In-One options, while R1234yf is an adjustable selection. Package fittings differ by version, so compare the selected option with your existing service connections. These are coupler accessories, not a complete refrigerant charging machine.

The adjustable style has top control knobs and separate connection fittings; compare this arrangement with the version your equipment requires.

The red and blue bodies identify the two service sides, helping you distinguish fittings while laying out the equipment.

The illustrated couplers show their different service-port openings, a useful reminder to match each side before selecting fittings.

The close-up shows the adjustable bodies and removable connection pieces; included fittings depend on the selected version.

This cylindrical style differs from the earlier couplers in both body and side connection, so choose by your service setup rather than colour alone.

The All-In-One illustration shows integrated side connections, distinguishing this option from versions using separate adapters.
