gohantee R134a Refrigerant Charge Hose Kit — 19" Can Tap with BPV31 Bullet Piercing Valves & Gauge

gohantee R134A Refrigerant Charge Hose Kit pairs a 19-inch R-134a can tap hose with a BPV31 bullet-piercing tap valve and pressure gauge for safe, accurate refrigerant topping and service.

This compact charging kit is built for technicians and DIYers who need a reliable way to add R134a refrigerant to automotive and small HVAC systems. It combines a corrosion-resistant metal can tap, a rubber high-pressure hose, a multi-scale gauge and two BPV31-style bullet piercing valves so you can attach to common service lines and cans. The design emphasizes a small installation footprint, tool-supplied assembly and compatibility with several pipe diameters and retrofit fittings.

How does the kit connect to cans and service ports?

The kit includes a 19-inch R-134a can tap with a 1/2-inch end that fits standard R12/R22/502 fittings, plus a 90-degree push-and-lock coupler that auto-shuts off when disconnected. Two BPV31 bullet piercing valves are supplied for creating service access on compatible tubing without removing lines. The gauge face is printed with scales for R134a, R12 and R22 to simplify reading.

• 1/2-inch can tap end fits common refrigerant cans and retrofit fittings
• 90-degree push-lock coupler with auto shut-off for clean disconnects
• Two BPV31 piercing valves for tapping into lines quickly
• Gauge calibrated for R134a, R12 and R22 refrigerants

What sizes and piping does the BPV31 valve support?

The BPV-31 bullet piercing valves in this kit are compatible with a range of outside pipe diameters and match many replacement part numbers. The valves work with 1/4", 5/16" and 3/8" OD tubing frequently found in automotive and small-system refrigeration work. They also replace common parts such as AP4502525 and GPV31-series components.

• Compatible with 1/4", 5/16", 3/8" OD tubes
• Replaces BPV31D, GPV14, GPV31, GPV38, GPV56, MPV31 parts
• Useful for retrofit or emergency tapping where a service port is absent

How easy is installation and what tools are required?

Installation is straightforward and designed to require minimal clearance and equipment. The kit ships with a single hex key wrench to assemble the components, and the can tap and gauge require about 2 inches of working space for mounting. Note: if you plan to attach the gauge directly to a bullet piercing valve, a separate retrofit valve may be required and is not included.

• Only one hex key provided for assembly
• Compact design needs roughly 2 inches clearance to install
• Retrofit valve sold separately if attaching gauge to piercing valve

What materials and durability features does the kit offer?

Components are made to withstand workshop conditions: the metal parts are corrosion-resistant and the hose uses reinforced rubber for reliable pressure performance. These choices reduce wear and the risk of rust while providing a long-lasting replacement option for service tools. The package contents include adapters to match common fittings so you can get to work quickly.

• Corrosion-resistant metal can tap and valves
• Durable rubber hose with good pressure resistance
• Includes two 1/4" to 1/4" adapters and two piercing valves

Who is this for: The gohantee R134A Refrigerant Charge Hose Kit is aimed at automotive technicians, HVAC maintenance technicians, and experienced DIYers who need a compact, proven charging and tapping solution. It suits users who work with R134a and legacy refrigerants, require quick-access piercing valves, and value a small-install footprint with clear gauge readouts and robust materials.
