[Shop-talk] alternate use for PEX fittings

[Peter J. Thomas]

Just my limited experience with replumbing a house with PEX using the SS 
band clamps.  They are fine until you start pulling and flexing on the 
tubes.  They can leak but will seal up once left alone.  This might be a 
problem in a truck.  The issue isn't the bands the issue is the PEX.  
The clamps are quite similar to crimped clamps used on modern cars.
