Return (Low-Pressure) Hose carries hydraulic oil back from cylinders and motors to the tank at low pressure. It’s made of rubber with one or two braided layers so it stays flexible but won’t pop if oil pushes back. We connect it from component outlets to the return manifold or tank, using clamps and fittings. If it leaks or gets stiff, oil spills and systems lose fluid. We swap it on the first sign of cracking. It’s the cleanup crew, collecting oil for another round.
