Collection:Hex Socket Plug Fittings

View Tameson's range of hex socket plug fittings. End caps, also called end plugs, only have 1 port. Therefore, they are used to close off ports for permanent setups or for maintenance, inspection, or repairs. A practical example of using a plug is to close off unused ports in a manifold block. These have hex socket threads for a connection point. They can have either a hex nut or hex socket design.
