BT0-7146 – EZ-Clip Male Insert O-Ring Straight Bulkhead Fitting (#8 Hose)

The BTRAC BT0-7146 EZ-Clip Male Insert O-Ring Straight Bulkhead Fitting is designed for secure bulkhead-mounted hose routing in mobile air conditioning and refrigeration systems. This fitting allows #8 EZ-Clip refrigerant hose to pass cleanly through panels or mounting surfaces while maintaining a reliable, leak-resistant seal.

Constructed from heavy-duty steel, this fitting is engineered to withstand vibration, pressure fluctuations, and harsh operating environments common in trucks, buses, off-road equipment, and transport refrigeration applications. The EZ-Clip design enables fast, consistent installation without crimping when used with the proper hose and installation tools.

All Aeroquip EZ-Clip refrigerant fitting kits include the fitting, cage, clips, and O-rings.
For use with Aeroquip GH134 EZ-Clip refrigerant hose ONLY.
