Aupoko R1234YF Refrigerant Charge Hose Kit — 1/2" LH Self-Sealing Can Tap with 200 PSI Gauge and Auto-Shutoff Coupler

This kit is designed for technicians and DIYers who need a reliable way to dispense R-1234YF refrigerant from sealed, left-hand (LH) threaded cans. The package combines a metal-bodied tap, durable rubber-reinforced hose, an inline pressure gauge and a 90° push-and-lock coupler with auto shutoff so you can control flow and monitor charge pressure without makeshift adapters. It’s intended specifically for self-sealing cans with a 1/2" LH thread and is not compatible with puncture-style or unrelated refrigerant cans.

How does this kit make charging R-1234YF easier?

The Aupoko kit removes the need for improvised connections and reduces refrigerant loss by using a self-sealing can tap and auto-shutoff coupler. The included gauge provides real-time pressure feedback, helping you dial in the correct charge faster and with more confidence.

• 1/2" LH threaded self-sealing can tap for leak-free attachment
• 90° push-and-lock coupler with automatic shutoff to prevent spillage
• Inline pressure gauge (200 PSI) for monitoring while charging
• Hose rated 600–3000 PSI for robust service use

Which cans and vehicles is this compatible with?

This tool is built to work with original R-1234YF sealed cans that use a 1/2" left-hand thread. It will not fit puncture-style cans or cans designed for different refrigerants such as R134a unless those cans explicitly state the same LH 1/2" thread interface.

• Compatible with R-1234YF sealed cans with 1/2" LH threads
• Not suitable for puncture/open-top cans or R-134a-specific replacement cans
• Includes 14mm low-side quick adapter for standard service ports

What are the build and safety features I should know about?

The hose assembly combines metal fittings and high-grade rubber to resist wear and maintain stable performance under pressure. Safety is addressed through a self-sealing valve system and the quick coupler’s auto shutoff, reducing accidental refrigerant discharge during hookup and removal.

• Solid metal tap and reinforced rubber hose for long-term durability
• Auto shutoff coupler minimizes refrigerant escape during disconnect
• Gauge and hose pressure ratings help avoid over-pressurizing systems

What’s included and what warranty is offered?

The kit ships with the 1/2" LH self-sealing can tap, a service hose rated for high pressure, a 200 PSI inline pressure gauge and a 14mm low-side adapter. Aupoko backs the product with a 12-month limited warranty covering manufacturing defects, giving a clear route for replacement or refund if the part fails within that period.

• Complete tap-and-hose assembly with gauge and quick adapter
• Intended for professional or advanced DIY automotive A/C charging
• 12-month warranty for workmanship and material defects

Who is this for: The Aupoko R1234YF Refrigerant Charge Hose Kit is aimed at automotive technicians, HVAC professionals, and experienced DIYers who work with modern vehicle air conditioning systems that require R-1234YF refrigerant and who specifically use sealed 1/2" LH threaded cans. If you frequently service R-1234YF systems and want a durable, ready-made tap and gauge assembly to speed up accurate charging and reduce refrigerant loss, this kit addresses those needs. Avoid purchasing if you use puncture-style cans or refrigerants with different fittings.
