Nipples

High-pressure nipples and connection adapters for waterjet circuits, in the usual diameters and thread combinations.

A nipple is a small part with a demanding job: it holds the joint at full working pressure, and the seal is made by the cone, not by the thread. That is why the cone has to be clean and undamaged, and why a nipple that has been over-tightened or re-used too many times should be replaced rather than re-fitted.

What identifies the part you need is the tube diameter at each end, the thread and the working pressure. If you have the old nipple, those figures can be measured from it directly.
