Clamping spiral wound hose onto fittings can be challenging. Standard hose clamps are too wide and sit on top of the hose spiral preventing them from properly clamping the hose wall to the fitting.
These wire clamps are the solution.
The narrow wire sits between the hose spiral, clamping the hose wall to the fitting. The 2 wire design is like having 2 clamps in one, placing pressure on the hose at 2 places ensuring double the opportunity for proper hose clamping.
