BACOENG R1234yf Refrigerant Charge Hose Kit — 42cm Low-Side Gauge, 1/2" Self-Sealing Can Tap

This compact charging kit combines a durable 42 cm (16.5") hose, a 0–100 PSI low-side gauge, a female 1/2" left-hand self-sealing can tap opener, and a low-side quick coupler so you can attach a refrigerant can and monitor pressure during routine automotive A/C topping-up. The parts are sized for R1234yf service and built for repeated use in workshop or home-garage settings.

How does this kit simplify recharging an R1234yf A/C system?

The kit centralizes the components you need to add refrigerant: hose, gauge, can tap, and coupler. Instead of sourcing adapters separately, you connect the self-sealing can tap to the refrigerant can, attach the hose via the 1/2" thread, and clip the quick coupler to the vehicle low-side port to read pressure and allow controlled charging.

• All-in-one set: hose, gauge, can tap opener, and low-side quick coupler.
• Self-sealing 1/2" female tap prevents spills when disconnected.
• 0–100 PSI gauge provides a clear low-side pressure readout.
• 42 cm hose length balances reach and control in tight engine bays.

Can I trust the fittings and gauge for workshop use?

The kit is built with standard-sized fittings intended for R1234yf work: a 1/2" left-hand female can tap and a low-side connection sized at up to 14 mm diameter. The mechanical pressure gauge is scaled 0–100 PSI for typical low-side measurements, making it suitable for routine diagnostic checks and charging steps.

• Female 1/2" LH can tap for common refrigerant cans.
• Low-side connector up to 14 mm diameter to match vehicle ports.
• Robust mechanical gauge with easily read 0–100 PSI scale.
• Metal fittings reduce wear from repeated hookups.

What safety and handling features are included?

The self-sealing can tap closes when disconnected to limit refrigerant loss and exposure. The quick coupler securely latches to the low-side service valve, and the short, flexible hose minimizes kinking while providing enough length for safe handling around engine components.

• Self-sealing can tap reduces leaks during swaps or storage.
• Quick coupler secures to the vehicle low-side service port.
• 42 cm hose offers control without excessive slack in engine bays.
• Mechanical gauge avoids electronics that can be damaged by refrigerant or oil.

Which vehicles and situations is this kit suitable for?

This charge hose set is intended for automotive systems that use R1234yf refrigerant and that accept low-side charging via standard service ports. It’s best for maintenance tasks such as topping off refrigerant, pressure checks, and simple troubleshooting—when used by people who follow safe refrigerant handling procedures.

• Designed for vehicles using R1234yf refrigerant only.
• Useful for topping-up and low-side pressure checks.
• Appropriate for garages, workshops, and knowledgeable DIYers.
• Not a replacement for full recovery/recharge equipment required by regulations.

Who is this for: The BACOENG R1234YF Refrigerant Charge Hose Kit is aimed at mechanics, service technicians, and informed DIYers who need a compact, purpose-built low-side charging solution for R1234yf automotive air conditioning. It suits routine topping-up and pressure monitoring tasks when used alongside proper refrigerant handling, safety equipment, and compliance with local service regulations.
