Professional HVAC Service Solution

The Supco BPV31 bullet piercing valve is engineered for convenience and efficiency. The clamping design securely fastens to the copper suction or liquid line, while the hardened piercing needle punctures the tubing to provide immediate system access. This makes it especially useful for older systems that do not have an existing service port.

For HVAC contractors and technicians servicing air conditioners, heat pumps, refrigerators, or sealed refrigeration systems, the Lennox Y8797 piercing valve reduces labor time and simplifies diagnostics.
