FANOVO Refrigerator Freon Recharge Hose Gauge Kit — R134a/R12/R22/R502, BPV31 Piercing Tap & Self‑Sealing Adapter

FANOVO's Refrigerator Freon Recharge Hose Gauge Kit is a complete charging set that lets you safely attach to refrigerator and home A/C refrigerant ports and refill R134a, R12, R22 and R502 systems using either piercing cans or self‑sealing cans.

This tool kit combines a pressure gauge, a piercing BPV31 tap valve, a low‑pressure quick coupler, a self‑sealing R134a adapter and assorted fittings so you can diagnose and top up common home refrigeration and small A/C systems. The gauges are color‑coded and rated to 350 psi for quick visual checks, while brass fittings and a reinforced rubber hose deliver corrosion resistance and leak reduction during charging tasks.

How do I connect the kit to a refrigerator or A/C low‑pressure port?

Attach the 1/4" SAE female end of the hose to the appliance service port and tighten until secure. For cans without self‑seal, use the BPV31 bullet piercing tap to puncture the canned refrigerant; for self‑sealing cans, screw on the included R134a self‑seal adapter before connecting. Open the valve slowly while watching the gauge to control flow.

• 1/4" SAE female port mates with common appliance male ports
• BPV31 piercing valve fits 1/4, 5/16, 3/8" OD pipes
• Self‑sealing R134a adapter accepts modern sealed cans
• Large colored dials provide easy reading (max 350 psi)

What refrigerant types and cans are supported by this kit?

The gauge reads pressures compatible with R134a, R12, R22 and R502 systems, covering most household refrigerators and many small HVAC units. The kit includes both a piercing tap for traditional refrigerant cans and a self‑sealing adapter for contemporary valve‑top cans, giving you flexibility across can types.

• Works with R134a, R12, R22 and R502 refrigerants
• Piercing valve for non‑self‑sealing cans
• Self‑sealing adapter for modern R134a cans
• Useful for home refrigerators and small A/C systems

Is the kit durable and safe to use?

FANOVO designed the components from corrosion‑resistant metal with anti‑leak features and a pressure‑resistant rubber hose to reduce wear and leaks during use. The quick coupler has a knurled anti‑slip grip and internal ball bearings for secure snap‑on connections, while the hex key and adapters allow correct installation of the piercing valve.

• Brass fittings resist corrosion and wear
• Rubber hose engineered for pressure resistance
• Self‑sealing and quick‑connect interfaces lower leak risk
• Rated components help maintain safe charging pressure

What comes in the FANOVO recharge kit and how do I maintain it?

The set ships with a BPV‑31 piercing valve, hex key, two adapters, a self‑sealing R134a adapter, a brass low‑pressure quick coupler with dust cap and the gauge hose assembly. After each use, purge residual refrigerant as recommended, cap fittings, wipe brass surfaces, and store in a dry case to prolong lifecycle and maintain seal integrity.

• Includes piercing valve, hex key, two adapters
• R134a self‑sealing adapter and brass quick coupler included
• Gauge hose assembly with large colored dials
• Store dry, cap coupler, and inspect O‑rings periodically

Who is this for: This kit is aimed at homeowners, hobby mechanics and HVAC DIYers who need a reliable, multi‑refrigerant charging tool for refrigerators and small air conditioning units. It suits users who want options for both piercing cans and modern self‑sealing cans, and who appreciate visible gauges and durable metal fittings for routine maintenance and small repairs. If you're uncertain about refrigerant handling or local regulations, consult a certified technician before use.
