You can easily create 90-degree bends in your pipes. For example, if you want to save space and make the hose change direction close to the pump, an elbow fitting will work best. Hoses may kink or start leaking if they are bent, which can be prevented by using an elbow piece that allows you to create bends safely. This Elbow 90 PP has a 1" female thread on one end and a male thread on the other, is rated for 10 bar pressure, and comes in black. The part number is 0121229.
