FAQs

At Hydra-Flex, only the best materials make the cut—because performance, durability, and longevity are non-negotiable. We use top-tier materials like 303-grade stainless steel and Tungsten Carbide because of their strength and resilience. Stainless steel resists corrosion in abrasive environments, while Tungsten Carbide is incredibly hard and prevents wear, deformation, and cracking under extreme pressure. We also coat our nozzles with protective materials like Hytrel and Urethane, materials that can withstand the elements and help protect underground utilities. Every material is carefully chosen to ensure long-lasting reliability.

Yes! Tungsten Carbide is significantly stronger than ceramic. It’s one of the hardest materials in the world, offering unmatched durability and resistance to cracking, even under high pressure. Unlike ceramic, which can shatter if dropped or started in the incorrect position, Tungsten Carbide maintains its integrity through constant use. That’s why we use it in our nozzles—for superior performance and longer lifespans of our products.

Flow-Straightening Technology is a patented feature in Hydra-Flex nozzles that ensures smooth, consistent water flow that creates a powerful, even spray pattern. This innovative design eliminates the uneven, swirling water flow commonly found in other nozzles which helps it perform more effectively and cut water usage. The result? Better performance, improved efficiency, and less water waste—WIN, WIN, WIN.

Hydra-Flex nozzles are designed for low-maintenance use. Since they operate exclusively with water, there’s no need for complicated or messy fluid maintenance. Simply rinse the nozzle at the end of the day to keep it in top working condition. It’s that easy, so you can focus on your job without worrying about equipment upkeep.

Why replace your nozzle when you can repair it? Hydra-Flex repair kits allow you to restore your nozzles to like-new condition without the high cost of a full replacement. By swapping out worn parts, you extend the life of your equipment, maintain peak performance, and save money. Most kits are designed for easy field installation in under 10 minutes, making them a smart, cost-effective solution to keep your operation running smoothly.

For the most effective blockage clearing, feed the nozzle up to the obstruction, then pull the hose back 6-12 inches (depending on pipe size). Next, push the nozzle forward into the blockage. This technique maximizes power and ensures the rotating stream reaches the full diameter of the pipe for maximum efficiency.

Hydra-Flex nozzles are engineered with specific temperature ratings to match their intended applications to ensure optimal performance, safety, and durability. For example, our Hydro-Excavation nozzles are designed to handle hot water, which helps break up frozen or compacted soil more effectively.

Here are the maximum water temperature ratings for each nozzle:

• Ripsaw HD: 180°F (+82°C)
• Switchblade: 180°F (+82°C)
• Machete: 180°F (+82°C)
• Reaper: 180°F (+82°C)
• Revolution: 180°F (+82°C)
• Marksman: 180°F (+82°C)
• Aqua-Rocket: 150°F (+65°C)
• Aqua-Rocket Pro: 212°F (+100°C)

Always ensure you use the nozzle within its specified temperature range for the best results and product longevity.
