Sprinkler Tool and Fifteen Shut-Off Caps

This combination kit includes one multi-function sprinkler adjustment tool and fifteen shut-off caps for spray heads. It is designed for irrigation maintenance, repair and temporary water control on residential or commercial systems.

Homeowners, landscapers and irrigation professionals

The set suits anyone who needs to adjust spray patterns, lift pop-up stems or isolate individual heads during testing or seasonal changes. It is not for installers who require permanent valve replacements or components for rotor-style heads outside the listed compatibilities.

Questions about this item

How do I install the shut off caps on my Hunter Pro Spray PS Ultra heads without damaging the nozzle?

Thread each green cap onto the PS Ultra head (part 916400SP) by hand until snug; the included tool lifts the pop-up stem so you can reach the threads without forcing the nozzle.

What maintenance will the caps and tool need after a season in the sun?

The UV-resistant plastic caps and tool only require a rinse to clear debris; inspect the cap threads each spring and replace any that show cracking or stripped threads.

At what pressure do the caps start to leak during a long zone run?

The caps are designed for standard residential irrigation pressure; sustained pressure above the system's normal operating range may cause seepage at the cap seal first.
