(4 Pack) Clear Elbow Female 90 Deg Fits 1/2 ID 5/8 OD Acrylic PolyCarbonate PVC Tube

If you apply any torque at all they will shatter, the plastic is far far too brittle for any conceivable usage. I was using them in conjunction with clear tubing 2 contain an LED project, but all 4 pieces broke

The ID is .610 and will not securely connect with a .50 tube/pipe. I would not recommend this product for any use unless there is a tube/pipe at .605/.610
