Irrigation Fittings & Accessories

Connect the dots in your landscape irrigation system with the hardware that actually makes it work. Our Irrigation Fittings & Accessories collection gives you the full toolbox of parts—from the mainline all the way to the end-cap—so your watering system stays efficient, leak-free and long-lasting.

Whether you’re installing a backyard sprinkler setup, adding drip-zones to garden beds, or doing a pro-grade job across a large property, the right fittings and accessories matter. Fittings allow you to change direction with elbows, join tubing with couplings, reduce sizes with adapters, terminate runs with end-caps, and fix issues without replacing the whole line.

In this collection you’ll find:

  • Connectors and couplings made for common pipe/tubing types (PVC, poly, PE, HDPE) used in landscape irrigation. 

  • Elbows, tees and adapters to change direction, branch one line into two or adjust to different diameters—essential for layout flexibility. 

  • End-caps, flush valves and termination accessories so cuts don’t turn into leaks and your system stays serviceable. 

At Big Frog Supply, we understand you aren’t just buying parts—you’re building a system that needs to perform. We bring you selections geared to DIYers, homeowners and pros alike, with clear specs and trusted brands.

Pro tip: Before installation, map out your tubing run and identify where angle changes or splits happen. Choose fittings accordingly, match the tubing diameter, and check for required pressure-ratings or UV exposure. Having spare adapters and end-caps on hand will make future expansions or repairs much smoother.

Browse the collection, pick the connectors and accessories you need, install with precision—and keep your irrigation system flowing right for years.
