Bulkhead fittings

A bulkhead fitting goes through a hole in a panel and is locked from behind with a nut. Both ends take a tube, so the line enters on one side and carries on from the other.Use it where a tube has to pass through a cabinet wall, base plate or machine panel. The fitting carries the pull so nothing ever tugs on the tube itself, and the panel stays sealed. Check the panel thickness against the clamping length first.
