You protect your skin from the sun's harmful rays, but did you know UV rays can also damage your plastic plumbing fittings? Standard plastic fittings, when exposed to sunlight, can break down and fail in as little as a year or two. While UV resistant is not UV proof, these fantastic outdoor-rated plastic fittings extend that life expectancy dramatically - think of it as a plastic planter designed for the outdoors as compared to a child's sand bucket left outside all year.

Specifically designed for water filtration and water softener installation where maintenance is regular and expected, the push-fit design is fantastic for many other types of repair and remodel applications too! For instance, many marine and RV plumbing systems are frequently exposed to the elements and over time the fittings can sustain serious damage - threatening your potable water supply or just being a pain in the neck to replace when you have to solder or crimp connections. Equipped with EPDM o-rings and manufactured from high quality engineered plastic, our UV resistant push-fit fittings are a breeze to install and built to last.

A great time saver for professionals and DIYers, there's no worrying about installing copper piping close to flammable material, no waiting for glue to dry on CPVC connections or worrying about repairs in tight areas where crimp tools won't fit. These amazing fittings also work to repair wet pipe, either under water or when you cannot stop the water flow completely, letting you get to that repair right away, so you can stop the leak faster. Help protect your property and install these fantastic UV resistant fittings today!


Please be aware: UV resistant is not UV proof - we do not recommend constant exposure to direct sunlight for any plastic fitting as we believe they can and will fail over time.

Frequently Asked Questions

Q. "How long can I expect these UV resistant fittings to last?"
A. These UV resistant fittings have a UV inhibitor integrated into the plastic, so they won't break down over the course of one or two seasons like most plastics do when exposed to consistent sunlight. This line of push-connect fittings have been put through high intensity testing and are rated for outdoor use, just like plastics used in automotive applications or any other outdoor plastic. You can reasonably expect them to last several years in direct outdoor sunlight, if not longer. If indoors, these fittings have a life expectancy similar to metal fittings. However, just like any part of your plumbing system, you must protect them from freezing.

Q. "Okay, so I can install them and forget about them, no matter where I put them?"
A. Nothing is foolproof and every plumbing system should be inspected regularly so small problems can be found and addressed before they become big ones. These fittings, like anything man-made, can and will eventually fail. These UV resistant fittings do, however, give you a dramatically longer life expectancy than standard plastic fittings when exposed to sunlight, are suitable for potable water, and are easy to install.
