Schedule 40 PVC fittings from Irrigation Direct are available in a wide variety of configurations and are the most common PVC fittings used in the irrigation industry. The term Schedule 40 refers to the strength and thickness of the PVC pipe or PVC fitting and how much pressure it can hold. Its designed to handle water pressures of 120 psi and water temperatures up to 140 degrees. Meets NSF and ASTM D2466 requirements. Manufactured from PVC Type 1, Grade 1.

Schedule 40 PVC fittings, (aka Sch 40), are general white in color and come available in two main connection options: Slip and Threaded.

Schedule 40 PVC slip fittings are solvent welded to PVC pipe using PVC cement. PVC cement is designed to melt plastic, creating aPVC Fittingsweld between PVC pipe and a PVC fitting.

Schedule 40 PVC pipe fittings are designed with pipe threads and are used to attach external items that also come with pipe threaded connections, such as irrigation valves, risers, ball valves and backflow preventors. Teflon tapeis required when installing threaded PVC fittings.

PVC and Schedule 40 fittings are very versatile and can be used to distribute air or water at high and low pressures. PVC fittings are also easy to install and generally cheaper than alternative materials. PVC fittings have a long lifespan and are highly resistant to corrosion and chemicals making them the preferred choice for sprinkler systems, drip irrigation systems, potable water, chilled water, irrigation, golf courses, and pools/spa applications.


Sprinkler irrigation systems are commonly used in lawn irrigation systems and other planted areas where a spray or mist is desirable. For plants that require uniform coverage of water (grass, ground cover, seeds) a sprinkler irrigation system is appropriate.

If you are installing lawn sprinkler irrigation systems, Irrigation Direct carries a variety of supplies and parts like an adjustable nozzles for Rain Bird sprinkler heads. Our shrub adapters are perfect for garden sprinklers and shrub zones.

Combine pop-ups and rotors with electronic sprinkler controllers (timers), and inline valves to automate your landscape sprinkler irrigation system. Browse our Sprinkler System Supplies and Parts to find sprinkler nozzles, bubblers, swing assemblies, cut-off risers, Marlex 90s, and more.


Drip irrigation is a watering method which delivers water to plants slowly and right where they need it at the roots. Where typical pop-up sprinklers spray water into the air and onto plants, drip irrigation systems combine flexible poly drip tubing and drip emitters or "drippers" to both conserve water and save money.

Drip irrigation systems are not affected by wind and will greatly reduce evaporation and runoff common with traditional irrigation systems. Drip irrigation is the perfect solution for raised vegetable garden beds, hanging baskets, and potted plants.
