The plumbing system in an RV is one of the things that gives it the convenience you are looking for. Without it, you would have to use the water from a campground spigot and use the camp bathroom instead of your RV bathroom. An RV is supposed to help you avoid these things, but if you're not taking good care of your water system, you might be forced to do so. While there are larger parts of the water system, including the tanks, the pump, and the various water fixtures, the small pieces are just as important. For example, your fittings are important to tie everything together. If a fitting isn't looking too great or just isn't working properly, it's time for a replacement.

Made of quality materials, these non-corrosive plastic fittings are built to last. This 1/2" to 3/8" barbed coupling connects two lengths of tubing, needing a crimp ring to further secure the connection. This tool-based fitting is durable, being non-corrosive and rust-resistant while creating a watertight connection. For a connection that will last you, make sure to check out this barb coupling fitting. NSF certified as well, it is suitable for freshwater lines.

When you're creating a new water system or fixing up an old one, you'll need high-quality fittings to put it all together such as this one. Have any questions? Contact us online or call our friendly Customer Care team today!
