Description
This brass fitting is designed to create a transition between PEX tubing and brass connections, making it easy to integrate PEX plumbing with new or existing water systems in RVs, camper vans, and marine water systems. It features a threaded ½” MPT connection on one side and a ½” barbed PEX connection on the other.
This plumbing fitting is constructed out of brass, which makes it durable and naturally resistant to corrosion and wear. The brass is also lead-free, making this MPT to PEX plumbing fitting ideal for providing reliable and leak-proof connections on fresh water applications.

This brass fitting is also very easy to install on your water system. First, apply thread tape to the threaded end of the fitting, then thread the fitting onto the connection point of your plumbing fixture. Use a wrench to tighten the fitting onto the connection. Now, measure and cut the length of PEX tubing you will need, then slide a copper crimping ring over one end of the tubing. Slide the end of the PEX tubing over the barbed end of the brass fitting, then slide the copper crimp ring over the connection. Then, use a crimping tool to secure the PEX tubing to the brass fitting.
If you’ve decided to update the water system of your RV, camper van, or marine vessel, then this ½” PEX x ½” MPT brass fitting will be a great way to help you integrate PEX tubing. Use our website to order yours today, or talk to our Customer Care Team if you need further assistance.
