Aupoko R1234YF Refrigerant Charge Hose Kit — 1/2" LH Self-Sealing Tap, 200 PSI Gauge

Aupoko's R1234YF Refrigerant Charge Hose Kit is a 1/2" left-hand threaded, self-sealing can tap with a 90° push-and-lock coupler, pressure gauge, and 14mm low-side adapter for charging R-1234YF cans safely and accurately.

This kit is built to connect directly to factory R-1234YF sealed cans that use a 1/2" left-hand (LH) thread. It combines a reinforced rubber hose, metal fittings, a 200 PSI gauge, and a locking quick coupler so technicians and experienced DIYers can control refrigerant flow, monitor pressure, and avoid spills while topping up A/C systems compatible with R-1234YF refrigerant.

How do I confirm this kit fits my R-1234YF cans?

Before ordering, verify your refrigerant cans use a 1/2" left-hand threaded, self-sealing dispenser. This tap only screws onto LH-thread sealed cans and will not work with puncture-style or different-thread containers.

• Check the can label for "1/2" LH" or "left-hand thread" information.
• Look for "self-sealing" on the can—puncture valves are incompatible.
• If uncertain, compare the can outlet to the kit's 1/2" LH fitting before use.

What safety and control features are included?

The kit is designed with a 90° push-and-lock coupler that shuts off automatically when disconnected, limiting refrigerant loss. A built-in 200 PSI pressure gauge gives a live readout for controlled charging, while the heavy-duty hose and metal fittings stand up to service use.

• Auto shut-off coupler to minimize leaks when disconnecting.
• 200 PSI gauge for immediate pressure feedback.
• 600–3000 PSI rated hose for robust service performance.

What components come with the charging hose kit and what are their specs?

The set includes the 1/2" LH self-sealing can tap, a reinforced service hose, a 200 PSI dial gauge, and a 14mm low-side quick adapter to reach typical A/C service ports. The hose is rated for high working pressures and the fittings are constructed from metal for durability.

• 1/2" LH self-sealing can tap compatible with R-1234YF sealed cans.
• Reinforced rubber hose rated 600–3000 PSI.
• 200 PSI analog pressure gauge for charging control.
• 14mm low-side quick adapter and 90° push-and-lock coupler with auto shut-off.

How do I install and use the Aupoko R1234YF hose safely?

Install by screwing the tap onto a compatible self-sealing R-1234YF can, attach the low-side adapter to the vehicle service port, then engage the coupler to start flow. Open valves gradually while watching the gauge to avoid overcharging and always follow vehicle and refrigerant handling safety guidelines.

• Ensure can thread matches 1/2" LH before connecting.
• Securely attach the 14mm adapter to the low-side port.
• Open the tap slowly and monitor pressure with the 200 PSI gauge.
