gohantee R134a Recharge Hose with Gauge — 51-inch AC recharging kit, self-sealing can tap & dual-scale gauge

gohantee R134a Recharge Hose with Gauge is a 51-inch AC recharging hose kit with a self-sealing can tap, low-side quick connector, and an integrated pressure/temperature gauge for topping off R134a, R12 or R22 systems.

If you perform occasional HVAC or automotive refrigerant maintenance, this kit provides a compact, ready-to-use solution to add refrigerant while monitoring pressure and temperature. The set combines a brass self-sealing can tap, a 51" rubber charging hose, R134a low-side adapter and a dual-scale gauge designed to show pressure and corresponding refrigerant temperatures. Built from copper/brass fittings and reinforced rubber hose, the kit aims for reliable connections during service and easier reading of charge conditions.

How does the gauge help me charge an AC system properly?

The integrated gauge displays both pressure and the equivalent refrigerant temperature scales so you can estimate charge condition while working. Reading pressure alongside the refrigerant temperature scales for R134a, R12 and R22 helps you decide whether the system is under- or overcharged under current ambient conditions.

• Dual-scale dial: pressure in psi/kg/cm² and temperature scales for R134a, R12, and R22.
• Clear red/blue markings help match pressure to refrigerant temperature ranges.
• 200 PSI maximum reading range suitable for low-side monitoring.

What fittings and hose features are included in the kit?

The kit includes a self-sealing can tap with 1/2" Acme female thread and 1/4" SAE male outlet, a 51-inch reinforced rubber charging hose and a quick-connect low-side adapter for R134a. All fittings are made from brass/copper materials to resist corrosion and seal reliably when properly tightened.

• Self-sealing can tap — works without puncturing cans, and is removable for safe storage.
• 51" durable rubber hose — long reach for vehicle or home AC ports.
• R134a low-side quick connector — snaps onto service port for fast connection.

Are there any safety or usage tips I should follow when using this recharge hose kit?

Before introducing liquid refrigerant, always hand-tighten and inspect all connections to prevent leaks, and ensure the can tap is correctly installed. Because the can tap and low-side connector are removable, verify seals and threads are free of dirt or damage and avoid over-tightening, which can damage fittings.

• Manually check and tighten every connection before charging to avoid leakage.
• Use the low-side gauge only for monitoring; avoid charging directly with liquid unless following manufacturer refrigerant instructions.
• Keep the gauge and tap clean and store disconnected to protect the self-sealing mechanism.

Who is this for: The gohantee R134a Recharge Hose with Gauge is aimed at DIY vehicle owners, HVAC hobbyists, and maintenance technicians who need a portable, easy-to-use low-side recharging solution for R134a and legacy refrigerants. It suits users who already understand refrigerant handling basics and want a quality hose and gauge combination for occasional topping-up, troubleshooting or pressure checks. Do not use if you lack refrigerant-handling training; always follow local regulations and safety guidance when working with refrigerants.
