I bought these because the resin joints of my pipe rack broke, but I was able to fix it using another method, so I didn't use them. They are less than half the purchase price. They can be used not only to fix pipes, but also to connect pipes in an L-shape using two clamps and one bolt and nut. Unused. If you want them to close tightly, the outer diameter of the 7A model should be 13mm, and the 10A model should be 18mm. (Bolts and nuts are also included)
