Adapter Assembly Prevents Damage to Tubing During High Pressure Tests

The problem: 
To prevent damage to tubing and injury to per-
sonnel when pressurizing a system or during high 
pressure tests. Frequently, the tube end would be 
damaged by the unsatisfactory method of attachment 
to the pressure source, or the connecting device would 
blow off the tube end because it would not hold in 
place under pressure. 
The solution: -
A portable adapter assembly that is capable of with-
standing high pressure is securely attached to the
tubing stub end, and may be removed without having 
to debraze, cut, or clean the tubing. 
How it's done: 
The tubing stub end has a brazed collar for me-
chanical attachment to the adapter. The split halves 
of the clamp assembly are secured to the tubing 
immediately behind the brazed collar and the tri-
angular plate is positioned in front of it. A rubber 
0-ring, which serves as a seal when compressed, is 
slipped over the tubing. The boss plate, with fittings 
for attachment to the pressure source, receives the
