gohantee R134a Charging Hose Kit with 2.75" Gauge — BPV31 Piercing Valve, 19.7" Reinforced Hose & Multi‑adapter

gohantee R134a Charging Hose Kit is a ready-to-use refrigerant recharge set featuring a 2.75" gauge, BPV31 piercing valve, and multiple adapters for R134a, R12 and R22 service connections. This compact kit combines a reinforced 19.68" charging hose, a clear analog gauge, a 3-in-1 piercing valve and essential adapters so you can access low-side service ports on automotive, mini-split and refrigeration systems. The gauge displays scales for R134a, R12 and R22 refrigerants and the included fittings suit common 1/4" and 5/16" lines, making the set useful for technicians and DIYers who need a lightweight, portable charging solution.

How does the gauge help me read different refrigerants?

The integrated 2.75" gauge is printed with multiple scales so you can reference pressures for R134a, R12 and R22 without swapping tools. This reduces setup time and keeps measurements consistent during charging or pressure checks.

• 2.75" analog dial with separate R134a/R12/R22 scales
• Clear markings for quick pressure interpretation
• Built into the hose assembly for one-handed operation

Can this kit pierce and connect to different tubing sizes?

Yes—the BPV31 3-in-1 piercing valve included in the kit is designed to tap into three common tubing diameters safely. It comes with adapters and a hex key so you can fit bullet-style lines and avoid cutting or soldering during temporary service tasks.

• BPV31 fits 1/4", 5/16" and 3/8" tubing
• Includes 1 valve, hex key and 2 adapters for secure tap setup
• Piercing design for quick temporary access without major system alteration

What adapters are included and what systems do they support?

The kit ships with a 1/4" low-side quick coupler, a 1/4" to 1/4" adapter with valve core, and a 1/4" male to 5/16" female adapter. These pieces expand compatibility so you can work on mini-split units, automotive A/C low-side ports, and many refrigeration lines using standard fittings.

• 1/4" low-side quick coupler for common service ports
• 1/4" to 1/4" adapter with valve core for inline control
• 1/4" male to 5/16" female adapter for mini-split and HVAC connections

How durable and serviceable is the kit for field use?
