I bought this to use with Clamptite to make a custom 4 tire inflator/inflator system and it is great for clamping rubber air hose fittings. I started with .051" but it was too stiff. The .041" is easy to work with and doesn't cut into the tubing at all like I had imagined for smaller diameter wire. I pressurized the system I made to 140psi and not a single fitting came loose.
