Alpmosn R134a AC Recharge Hose Kit with Gauge for Auto Air Conditioning

High‑Strength and Corrosion Resistance Built from aluminum alloy, the kit is pressure‑resistant, corrosion‑proof, and resistant to deformation. Good thermal conductivity helps balance temperature, stabilize pressure, and improve charging accuracy. Easy Installation and Operation No complex tools needed. Just connect to the refrigerant can and vehicle low‑side AC port. Simple enough for anyone to complete the refill. 1/2‑Inch Piercing‑Style Tap Valve The piercing tap is made of high‑quality aluminum alloy, compatible with US and European standard cans. Only fits piercing‑type R134a refrigerant cans. Precise Built‑in Pressure Gauge Precision gauge monitors real‑time AC pressure for quick troubleshooting. R134a Low‑Side Quick Coupler 90° push‑and‑lock coupler for fast, one‑handed connection and disconnection, even in tight engine bay spaces.

• 【Dimension】Features 17.9‑inch rubber hose, aluminum alloy 1/2‑inch dispensing valve and low‑side quick coupler. T‑type knobs fitted with sharp inner pins quickly pierce refrigerant cans. This tool works only with piercing‑type cans.
• 【Practical Functions】The 2.76‑inch gauge displays real‑time AC pressure to assist system checks. Control valve supports precise refrigerant charging for proper fill levels, with a 250 PSI maximum working pressure for consistent performance.
• 【Easy Installation】Connect self‑sealing valve to refrigerant can, attach low‑side coupler to AC port, open valve and charge slowly while observing gauge. No extra tools required.
• 【Important Notes】Gauge includes R134a, R22, R12 scales, but this tool is designed for R134a only. Never mix different refrigerants. Residue may harm equipment if parts are not cleaned between applications.
• 【Kit and Support】Kit includes recharge hose with gauge, piercing tap and low‑side coupler. Please inspect all components upon receipt. Should you have any questions, please reach out to our support team for assistance.
