    Abstract: A bending and support bracket for non-rigid tubing such as polybutylene water distribution conduit includes a frame having end portions extending at substantially right angles to each other wherein each end portion has a bracket for supporting opposite ends of a bend to be formed in the tubing. A curved bend support surface is formed on the frame between the bracket portions and is provided with a flange which together with the frame provides lateral support for a major portion of the bend of the tubing.
