Schneider Electric (Barber Colman) B-139 Bulkhead Compression Fitting 3/8" Barb X 3/8" 25-Pack

The Schneider Electric Barber Colman B-139 is a set of 25 bulkheads used to connect copper tubing to compressors and other HVAC/R components. Each bulkhead has a 3/8 inch barb on one end and a 3/8" compression fitting on the other. After inserting the barb end into the copper tubing, a crimp ring is utilized to secure the connection. The compression fitting is attached to the compressor or other equipment's threaded end by screwing it on.  They are frequently found in refrigerators, air conditioners, and other HVAC systems. The B-139 bulkheads are made of sturdy nickel-plated brass for long-term performance and are simple to install with common crimp tools.
