Features:
- The internal pin is connected with the upper knob to realize the adjustable function. While using, CCW switch the knob to close the R134a coupler, fasten it to the AC service port, then CW switch the knob to lift the internal pin to insert and push back the Schrader valve core slowly. Compared with the push to insert directly, this design can reduce the wear of the AC service port valve core by the internal pin, and ensure no refrigerant leakage when connect and disconnect
- Snap lock quick interface at the bottom of R134a adjustable quick couplers implements the quick function. Outside of the adjustable quick connection interface, there is an anti-slip knurled grip ring, and inside of the interface, there is an accurate snap lock with ball bearings design, which compatible with all mode of R134a service ports by quickly connecting and disconnecting.
- The blue low pressure R134a quick connector, connects AC manifold gauge blue hose 1/4″ Female parts to auto AC suction service port. And the red high pressure R134a quick coupler adapter, connects AC manifold gauge red hose 1/4″ Female parts to auto AC discharge service port. Clockwise switch the red/blue knob to open AC service port, counterclockwise switch to close. We have marked it on the labels of the knobs. Very easy to use.
- The R134a can tap can be tightened and fastened on the 1/2″ ACME Male thread of the R134a bottle opening. The 1/4″ Male thread on the side can be connected to the 1/4″ Female parts on AC refrigerant charging hose directly. By ACME tank adapter (1/4″ Female to 1/2″ Male), it can be connected to the 1/2″ Female one. The special designed T style knob is very convenient for finger operation. And the sharp pin inside helps to pierce self-piercing R134a can easily and quickly
- These air conditioning adjustable quick couplers use high quality brass and aluminum material, and the refrigerant can tap valve body and the ACME adapter also adopt superior brass material, very hard, wear resistance and anti-corrosion, very suitable as corrosive refrigerant accessories. Also there are rubber seal rings inside, ensure the gas tightness and no leak.
