patriciogac: few hints for tighter bending radius - it's good to have tubing to form something like half-circle with even bend in all it's length (if tubing is longer, it tends to kink in middle, if it's shorter, it tends to kink near both fittings); +you can put something like spring or something else inside tubing similar to it's ID to prevent collapsing of it and submerse peace of bent tubing in hot water cup or bowl of needed size to soften tubing material. After cooling down it should retain it's bent shape. I've heard good results regarding small bend radius without kinking about primochill pro LRT tubing.
