How to Install a Bulkhead Connector How to Install a Bulkhead Connector

What You'll Need
Paddle drill bit
Bulkhead connector
Crescent wrench
Eye goggles
Utility knife

A bulkhead connector is a type of fitting or coupler that goes into a physical barrier such plastic, wood, tile, or drywall. It can be used to connect two pieces of piping together or be used to add a faucet into a barrel. The installation of this type of connector is a very simple task for anyone involved in DIY plumbing.

Step 1 – Preparation

Determine the size of the pipes to be connected together to determine the size of the connector needed. If you are installing the fitting to a barrel, use the size of the faucet to determine its size. The installation of the fitting will require drilling into the physical barrier. A paddle drill bit works for plastic and wood, but a hole saw may also do. Use a tile bit when installing the connector through a tile.

Step 2 – Drill the Hole

Put the drill bit into the drill, but ensure that it is the correct size for the hole to be made. Determine the diameter of the cylindrical portion of the connector to get the correct diameter of the hole.

Always wear eye goggles when drilling through solid material. Mark the hole precisely where it has to be made. Connect the drill to a power supply and position the bit just above the surface of the marked area. Switch the drill on and allow the bit to drill through the barrier. Clean the burrs on the hole using a utility knife. Use a sandpaper to remove any leftover debris. Clean the hole with a cloth.

Step 3 – Inspect the Parts of the Fitting

Check if all the parts of the fitting are present. Inspect the rubber gaskets for any signs of damage. Before the installation process, ensure that any torn or damaged rubber gaskets, washers and nuts are replaced. Do not install any part of the connector when they are obviously damaged.

Step 4 – Install Each Part Correctly

The fitting will consist of a locknut, two rubber gaskets and a threaded cylindrical piece. The rubber gaskets ensure that the installation does not cause any leaks on both sides of the wall or barrier while the nut locks the connector in place. However, some models come with other more sophisticated parts. Check the user’s manual for proper order of installation if this is the case.

Before inserting the threaded part of the connector into the hole, insert a rubber gasket into it. Insert the threaded portion of the cylinder into the hole first. On the other side of the barrier, fit the other rubber gasket into the cylinder. Afterwards, screw the nut onto the threads and hand-tighten it. The nut may either be square or hexagonal in shape. Use a crescent wrench to tighten it further and make it leak proof. Do not over-tighten the connection to avoid damage. Once the installation is done, connect the pieces of tubing to the fitting.
