How to Connect PEX to Tub Spout?

If you’re looking to replace your old tub spout or install a new one, you might be wondering how to connect your PEX tubing to it. There are several options to choose from, including specialized couplings, connectors, T-connectors, compression couplers, clamp-on adapters, and expansion joints.

In this article, we’ll discuss each option in detail and guide you on how to connect PEX to tub spout.

Specialized Coupling

The best way to connect PEX tubing to a tub spout is by using a specialized coupling. This coupling is designed specifically for PEX tubing and can connect it to various types of fixtures, including tub spouts. The coupling is easy to install and provides a secure connection that prevents leaks.

To use a specialized coupling, you’ll first need to measure the diameter of your PEX tubing and the diameter of your tub spout’s male thread. Once you have these measurements, choose a coupling that fits both sizes.

Then, simply slide the coupling over the PEX tubing and screw it onto the male thread of the tub spout. Tighten the coupling with pliers to ensure a secure connection.

PEX Connector

Another way to connect PEX to a tub spout is by using a PEX connector. This is a one-piece connector that has a female fitting on one end and a male fitting on the other end.

To use a PEX connector, you’ll first need to unscrew the female fitting from the tube and then screw it onto the PEX connector. Then, slide the male fitting onto the tub spout’s male thread and tighten it with pliers.

T-Connector

A third option to connect PEX to a tub spout is by using a T-connector. This connector has a female fitting on one end and two male fittings on the other end.

To use a T-connector, slide the female fitting onto the PEX tubing and tighten it with pliers. Then, screw one male fitting onto the tub spout and the other male fitting onto a shower head.

Compression Coupler

Another way to connect PEX tubing to a tub spout is by using a compression coupler. This is a two-piece connector that has an inner male fitting and an outer female fitting.

To use a compression coupler, slide the inner male fitting onto the PEX tubing and tighten it with pliers. Then, screw the outer female fitting onto the tub spout’s male thread and tighten it with pliers.

Clamp-on Adapter

You can also use a clamp-on adapter to connect PEX tubing to a tub spout. This adapter has a female fitting that slides onto the PEX tubing and a male fitting that screws onto the tub spout.

To use a clamp-on adapter, slide the female fitting onto the PEX tubing and tighten it with pliers. Then, screw the male fitting onto the tub spout’s male thread and tighten it with pliers.

Expansion Joint

An expansion joint is a unique and innovative way to connect PEX tubing to a tub spout without the need for any additional connectors or fittings. This type of joint allows you to connect two pieces of tubing without any joins between them.

To use an expansion joint, you first need to remove the old showerhead from the tub. Then, use the connector to connect one end of the PEX tubing to the showerhead and the other end of the PEX tubing to the existing tub spout. Make sure that both ends of the tubing are tightly connected.

Expansion joints are a great option if you want a cleaner and more seamless look for your bathroom. They are also a good choice if you’re concerned about the durability of the connector since there are no additional fittings to worry about.

However, one downside of using an expansion joint is that it can be a bit more difficult to install than other connector options. It may also require a bit more space to install properly, so be sure to measure your bathroom space before considering this option.

Now that we’ve covered the different ways to connect PEX tubing to a tub spout, let’s talk about some important tips to keep in mind when doing this project.

Tips for Connecting PEX to Tub Spout

• Before you begin, make sure you have all the necessary tools and materials on hand. You’ll need PEX tubing, a tub spout, and connectors or fittings if you choose to use them.
• Measure the space carefully to ensure you have enough room to install the connectors or fittings you’ve chosen.
• Always follow the manufacturer’s instructions carefully when installing PEX tubing and connectors or fittings.
• Use a pipe cutter to cut the PEX tubing to the correct length. Make sure the cut is clean and straight.
• Use a deburring tool to remove any burrs from the cut end of the PEX tubing.
• Use a crimping tool or clamp tool to connect the PEX tubing to the connectors or fittings.
• Test the connection carefully before turning on the water to ensure there are no leaks.
• If you’re unsure about any part of the process, consult a professional plumber for assistance.

By following these tips, you can ensure a successful and safe installation of your PEX tubing to your tub spout.

Conclusion

Connecting PEX tubing to a tub spout may seem like a daunting task, but it’s actually quite simple with the right tools and techniques. Whether you choose to use a specialized coupling, a PEX connector, a T-connector, a compression coupler, a clamp-on adapter, or an expansion joint, be sure to follow the manufacturer’s instructions carefully and measure the space before installation.

With the right tools and techniques, you can connect your PEX tubing to your tub spout quickly and easily, creating a seamless and durable connection that will last for years to come.
