TTQ 4-Pack Sprinkler Head Caps for Hunter Pro Spray Sprinklers – Fluoroelastomer Seals & O-Ring

Overview

TTQ's 4-pack sprinkler head caps are crafted for HUNTER Pro spray models PROS-04, PROS-06, PROS-12, PRS30, and PRS40. The caps combine durable black plastic with a precise fluorinated elastomer O-ring to create a reliable seal for unused nozzles.

Important compatibility notice: these caps are not compatible with Hunter PGP/PGJ/I-series rotor heads, PS spray heads, or other brands. Please verify your nozzle model before installing to ensure a secure fit.

Why seal unused nozzles?

Sealing off unused nozzles helps conserve water by stopping unintended spray where it isn’t needed. You can convert a traditional spray setup into a water-saving irrigation system without digging or replacing components, preserving your existing layout while cutting waste.

The cap and O-ring are designed to withstand outdoor conditions and sun exposure. The cap body resists cracking in heat and fading in bright sunlight, while the rubber seal remains flexible to maintain a tight barrier at typical irrigation pressures.

• Seal off unused heads with a tight O-ring to reduce leaks and evaporation.
• Weather-resistant plastic stands up to sun, rain, and temperature swings, ensuring long service life.
• Guard against dirt and debris, helping prevent clogs and keeping heads cleaner between seasons.

What you get and how to install

• What’s in the pack: 4 x sprinkler head caps with fluoroelastomer seals
• Fast, tool-free installation: simply hand-tighten the cap onto an unused head; no tape or tools required
• Reliable performance: the fluorinated O-ring works with standard irrigation pressures to maintain a solid seal

Real-world use scenarios: In a home garden, these caps let you turn watering off on shaded zones while keeping nearby grass green. They also provide a quick option to reduce irrigation in drought-prone seasons without reconfiguring the entire system.
