PVC pipes
PVC pipes can be spliced with solvent or compressed (by means of a seal).
On the market these types of pipe for hydraulic use are sold with a diameter of 32, 40 and 50 mm.
Tubes with a diameter greater than 63 mm on are equipped with a 'glass' at the end, ie; of a joint that allows them to be joined directly.
Clearly, joints and bends are on the market for every situation.
