Nut insert adapters provide a connection between compatible pipework and components using a union nut or insert arrangement. They are often used around manifolds, valves or other equipment where a demountable threaded connection is required.
Because these adapters serve a specific interface, dimensions, thread type, sealing method and pipe compatibility must all be confirmed before ordering. Similar-looking nuts and inserts may use different threads or sealing faces.
Prepare the pipe side in accordance with the relevant system instructions and assemble the nut connection without cross-threading or over-tightening. Use the specified seal or washer and ensure the finished adapter remains accessible where future disconnection may be needed.
