Hunter 916400SP Pro-Spray Shut-Off Nozzle Cap - Fits Male-Riser Sprays

The Hunter 916400SP Pro-Spray Shut-Off Nozzle Cap lets you quickly cap and shut off individual spray heads without removing the pop-up body. Designed for use with Hunter PS Ultra and Pro-Spray sprinkler bodies, this durable cap keeps heads visible while stopping flow at the nozzle and can double as a drip indicator when retrofitted to a drip line.

• Direct P/N fit: 916400SP designed specifically for PS Ultra and Pro-Spray sprinkler bodies.
• Broad compatibility: Works with most spray nozzles that have a male threaded riser (Rain Bird, Irritrol, and many others).
• Not compatible with Toro models that use a female riser; verify riser threading before purchase.
• Simple installation: screws onto a male threaded riser for quick capping - no major modification required.
• Useful diagnostic tool: keeps the head visible, isolates a zone, and can show drip flow when connected to drip lines.

Manufactured to match Hunter replacement part standards, the 916400SP is a convenient, low-cost solution for temporarily disabling spray heads during repairs or seasonal adjustments. Check your riser thread type before installing; contact Hunter support or a local distributor for confirmation if uncertain.
