BPV-31 Piercing Valve Kit – Refrigerant Line Tap for Copper Tube Repair
The BPV-31 Piercing Valve Kit is the go-to solution for DIY homeowners and HVAC technicians who need to quickly access refrigerant lines on refrigerators, freezers, and other cooling appliances. Made from durable zinc alloy, this compact line tap valve fits seamlessly into tight compressor spaces and gets the job done in about five minutes — no welding required.
Made in Mainland China.
Key Features
- Universal HVAC Repair Tool: Designed for domestic refrigerators, chest freezers, and other cooling systems. The valve body measures 4.35 × 3.4 cm (1.71" × 1.33"), making it ideal for compact compressor spaces.
- Quick 5-Minute Setup: Skip complex welding — a triple-bolt locking mechanism and included hex wrench let you securely tap into existing refrigeration lines in minutes.
- Versatile 3-in-1 Fit: Includes two removable adapter inserts to fit three standard copper tube outer diameters: 6mm (0.25"), 8mm (0.31"), and 10mm (0.375"). One kit covers the most common pipe sizes.
- Proven Leak-Proof Seal: A thick green rubber gasket surrounds the piercing needle, creating a tight barrier under high pressure. The heavy-duty sealing ring prevents gas leaks during refrigerant recharging or system evacuation.
- Broad Application: Ideal for apartment laundry rooms, basement crawlspaces, and compact utility setups — anywhere you need fast, reliable access to a cooling system's refrigerant lines.
