gohantee R134a Recharge Hose with Gauge — 51-inch AC recharging kit, low-side gauge

gohantee R134a Recharge Hose with Gauge is a 51-inch AC recharging kit that lets you tap, measure, and top up R134a (and compatible R12/R22 mappings) from a self-sealing can to a vehicle or home air-conditioning low-side port.

This compact service kit combines a self-sealing can tap, a 51-inch reinforced charging hose, and a readable low-side gauge so you can refill refrigerant with clearer pressure and temperature feedback. Built from copper and durable rubber, the assembly is intended for hobbyists and technicians who need a portable, easy-to-use tool for low-side charging and diagnostics. The gauge face includes combined temperature/pressure scales for R12, R22 and R134a so you can interpret readings quickly without separate charts.

How do I connect the can tap and hose safely?

Attach the self-sealing can tap to an R134a refrigerant can using the 1/2" Acme female thread, then connect the 1/4" SAE male end to the 51" charging hose. Make sure all threaded connections are hand-tight and check the removable low-side quick connector before adding refrigerant to prevent leaks.

• Use the 1/2" Acme female R-H thread for threaded R134a cans.
• Install the 1/4" SAE male into the hose fitting securely.
• Attach the low-side quick connector to the vehicle's service port until it clicks.
• Manually inspect fittings for tightness before dispensing liquid.

What exactly does the gauge display and why does it matter?

The included 200 PSI gauge shows both gas pressure and temperature equivalents for multiple refrigerants on a single dial. The colored scales map pressures to approximate temperatures for R12 (outer red), R22 (inner red), and R134a (blue), plus a black pressure scale in psi and kg/cm² so you can make informed charging decisions without converting units.

• 200 PSI max reading covers typical low-side pressures during service.
• Blue scale equals R134a temperature equivalents for quick reference.
• Dual-unit black scale shows psi and kg/cm² pressure readings.
• Color-coded rings speed up interpretation under workshop lighting.

Can I use this kit with multiple refrigerant types?

Yes — the can tap and gauge are designed for common refrigerants and the dial includes reference circles for R12 and R22 while the blue scale covers R134a. The kit is primarily intended for low-side charging and comparison reading; always follow refrigerant safety and compatibility rules applicable to your vehicle or system.

• Self-sealing can tap fits R134a cans; suitable for reference to R12/R22 mappings.
• Low-side adapter is removable for storage or replacement.
• Materials (copper and reinforced rubber) resist typical workshop wear.
• Not a substitute for full-service manifold sets for high-side service.

Who is this for? The gohantee R134a Recharge Hose with Gauge suits DIYers, fleet mechanics, and HVAC hobbyists who need a portable, no-puncture can-tap solution for low-side refrigerant refill and quick pressure/temperature checks. It’s ideal when you want a straightforward, durable hose-and-gauge kit for topping up R134a or for cross-referencing R12/R22 values, but it is not a complete multi-line manifold for advanced repair shop needs.
