gohantee R-134a Refrigerant Charge Hose Kit — BPV31 Bullet Piercing Tap, 19in Hose & Gauge

gohantee R134A Refrigerant Charge Hose Kit is a compact, corrosion-resistant charging assembly with a built-in gauge and BPV31 bullet piercing tap valves for easy R-134a service and retrofit connections.

This all-in-one charging hose kit is designed for automotive and HVAC technicians who need a durable, portable solution for topping up or diagnosing R-134a refrigerant systems. The kit combines a 19-inch R-134a can tap hose, a pressure gauge calibrated for multiple refrigerants, two BPV-31 bullet piercing tap valves, adapters, and a hex key — providing the essentials to access service ports and disposable cans safely and more efficiently than jury-rigging connections.

How does this kit connect to R-134a cans and service ports?

The included can tap attaches to standard R-134a disposable cans and routes refrigerant through the 19-inch rubber hose to the vehicle or equipment service port. A 90-degree push-and-lock coupler with an auto shut-off helps prevent refrigerant loss when disconnecting, and the hex key provided secures the piercing valve components.

• 19-inch hose with R-134a can tap for disposable cans
• 1/2 inch end compatible with R-12, R-22, R-502 fittings
• 90-degree push-and-lock coupler with automatic shut-off
• Hex key included for secure installation

What readings and refrigerants does the gauge support?

The integrated gauge face is printed with scales for R-134a, R-12 and R-22, making it useful for a variety of refrigerant checks and basic service work. While it provides pressure readings helpful for diagnosis and charging, it should be used alongside manufacturer specifications and charging charts for accurate refrigerant mass or weight measurements.

• Multi-refrigerant gauge face (R-134a, R-12, R-22)
• Pressure-focused display for system checks
• Suitable for visual diagnosis and rough charging guidance

Which fittings and pipes are compatible with the BPV-31 valve?

The BPV-31 bullet piercing tap valve is designed to fit a range of pipe sizes and common retrofit valve configurations. It replaces several common part numbers and accepts 1/4", 5/16", and 3/8" outside diameter pipes, making it adaptable to different OEM lines and aftermarket retrofit situations.

• Replaces AP4502525, BPV31D, GPV14, GPV31, GPV38, GPV56, MPV31
• Compatible with 1/4", 5/16", 3/8" OD pipes
• Includes two BPV-31 piercing tap valves and two 1/4" to 1/4" adapters

How durable and easy to install is the assembly?

gohantee built the kit using corrosion-resistant metal components and a pressure-rated rubber hose for long-term reliability under normal service conditions. Installation is straightforward and requires only the included hex key; the compact valve body works in tight engine-bay or equipment spaces that have at least a two-inch clearance.

• Metal parts resist rust and wear
• Rubber hose resists pressure and flex fatigue
• Compact design requires minimal 2" clearance for fitting

Who is this for: This gohantee R134A Refrigerant Charge Hose Kit is aimed at independent mechanics, HVAC technicians, fleet maintenance crews, and DIY-savvy vehicle owners who perform routine refrigerant checks or occasional top-ups. It provides a portable, economical option for accessing disposable cans and system ports, but it is not a substitute for full recovery/recycle equipment where local regulations or heavy service demand certified recovery procedures.
