gohantee R134a Recharge Hose with Gauge 51" — 200 PSI, Self-Sealing Can Tap for AC Recharging

gohantee's 51-inch R134a Recharge Hose with Gauge is a self-sealing refrigerant refill kit designed to safely connect R134a (and compatible R12/R22 adapters) cans to an AC low-side port while giving you a clear pressure and temperature readout.

This compact, all-in-one recharging hose kit combines a self-sealing can tap, a flexible 51" rubber hose, a 200 PSI gauge with multi-scale readings, and a low-side quick connector so vehicle or home air conditioning systems can be topped up precisely. Built from copper and durable rubber components, the tool is intended for DIYers and technicians who need a portable, accurate way to add refrigerant without puncturing cans or guessing pressures. The gauge face maps R-12, R-22, and R-134a temperature equivalents in °C, and also shows pressure in psi and kg/cm² for straightforward interpretation.

How does the self-sealing can tap work and why is that useful?

The can tap uses a self-sealing valve that threads onto standard refrigerant cans (1/2" Acme female R-H thread and 1/4" SAE male connection) so you don’t puncture the can until the connection is secure. This reduces mess and refrigerant loss and lets you disconnect without uncontrolled venting. It’s especially helpful when you need to swap cans or stop charging quickly.

• Self-sealing valve prevents accidental leaks when attaching/detaching.
• Standard 1/2" Acme and 1/4" SAE fittings fit common refrigerant cans.
• Manual installation recommended to verify tight seal before adding liquid.

What readings does the gauge provide and how do I read them?

The included 200 PSI gauge displays pressure in psi and kg/cm² on the black scales and converts to approximate refrigerant temperatures in °C for R-12, R-22 and R-134a using colored rings. The red rings show R-12 and R-22 temperature equivalents, while the blue scale corresponds to R-134a. This combined pressure/temperature layout helps estimate a correct charge without needing additional tools.

• 200 PSI maximum gauge with psi and kg/cm² scales for pressure monitoring.
• Red rings indicate R-12/R-22 temperature equivalencies on the face.
• Blue scale maps R-134a temperature at current pressure in °C.

Is the hose kit durable and safe for regular use?

The hose and connectors are built from high-quality rubber and copper components for stable performance and long-term service. The low-side quick connector is removable for maintenance or replacement, and the gauge construction supports routine DIY and shop use. Always check fittings manually before charging to prevent leaks and follow refrigerant handling safety procedures.

• Copper fittings for corrosion resistance and reliable sealing.
• Flexible 51" rubber hose for reach and ease of connection.
• Removable low-side adapter and self-sealing tap for serviceability.

Which systems and refrigerants can I use this kit with?

The kit is designed primarily for R134a systems and includes markings to interpret R-12 and R-22 equivalencies; use only compatible refrigerants and adapters. It works with automotive low-side service ports and many home AC units that accept R134a or require equivalent pressure-temperature reference. Do not use this tool with incompatible refrigerants or under pressures beyond the gauge rating.

• Intended for R134a systems; R-12/R-22 references on gauge for comparison.
• Suits vehicle low-side ports and compatible home AC recharge points.
• 200 PSI gauge limit — avoid exceeding rated pressure for safety.

Who this is for: This gohantee recharge hose kit is suited for DIY car owners, independent mechanics, and HVAC hobbyists who need a portable, easy-to-read solution for topping up R134a systems without punching cans. It’s also useful for service technicians who want a simple, removable low-side adapter and a combined pressure/temperature gauge to speed routine checks. If you work with different refrigerants regularly, pair the kit with appropriate adapters and always follow local refrigerant handling regulations.
