A PPR U-bend makes a smooth 180 degree turn in a PPR line.
It reverses a line with low flow loss. In addition, U-bends form expansion loops on long hot runs.
What is a PPR U-bend?
A PPR crossover, also called a bridge, is a curved pipe fitting that lets one PPR line pass over another without connecting to it. A U-bend makes a smooth 180 degree turn.
These fittings keep hot and cold lines neat where they cross. As a result, installers avoid awkward elbows and extra joints.
