Plugs Caps & Locknuts

Plugs are designed to insert into the end of tubing to dead-end the flow.  Various materials are used to manufacture high quality tube plugs in a variety of end connections.

Lock nuts are designed to prevent nuts from working loose. ... The most common form of a nut has a nylon inset built into one side of the threaded end. When the nut is tightened, the thread on the bolt stretches the nylon, causing the nut to grip the bolt which stops it from loosening itself.
