Hydro-Rain BL-406-005 - 1/2" Blu-Lock Elbow

Revolutionize your sprinkler projects with the Hydro-Rain 1/2" Blu-Lock Elbow. Achieve a secure, leak-proof 90° turn in seconds—no glue, clamps, or tools required. Simply push to connect.

Revolutionize Your Irrigation Projects: The End of Glues and Clamps

Forget the messy purple primer, the toxic glue, and the frustrating wait for PVC to cure. Stop wrestling with clamps and difficult barbed fittings that require immense force to install. The Hydro-Rain 1/2" Blu-Lock Elbow represents a fundamental shift in how irrigation systems are installed and repaired. It’s the faster, greener, and easier way to achieve professional-grade results, whether you're a seasoned contractor saving valuable time on the job or a first-time DIYer tackling a weekend project. This innovative fitting eliminates the need for chemicals and specialized tools, protecting both the environment and the long-term health of the installer. With Blu-Lock, you can execute flawless, durable connections with a simple push, transforming a once-tedious task into a quick and satisfying one.

The Blu-Lock Difference: Unmatched Speed and Patented Reliability

The Blu-Lock system is engineered from the ground up to outperform traditional irrigation methods in every key metric. Its patented design features deliver a combination of speed, security, and efficiency that is unmatched in the industry. This technology is not just an improvement; it's a complete re-imagining of how water-tight connections are made.

• Patented 'Push-and-Go' Technology: The heart of the Blu-Lock system is its revolutionary push-fit mechanism. This 100% tool-free and chemical-free approach allows you to create a secure connection in a fraction of the time it takes to glue PVC or clamp poly pipe. Simply make a clean cut on your tubing and push it into the fitting with a slight twist until it seats firmly. This process is so efficient it has been shown to cut installation time in half, allowing professionals to complete more jobs and homeowners to finish their projects faster.
• Leak-Proof Stainless Steel Grip: Confidence in an irrigation fitting comes from its ability to hold fast under pressure, season after season. The Blu-Lock elbow features a patented retaining system with a ring of rugged stainless steel teeth. These teeth grip the outside of the pipe, creating an exceptionally strong, leak-proof seal that holds tight against water pressure, ground movement, and temperature fluctuations. This robust internal mechanism ensures a connection you can bury and forget.
• Superior Flow and Efficiency: Traditional insert fittings, which go inside the pipe, create a bottleneck that restricts water flow and reduces system pressure. Blu-Lock fittings utilize innovative Outside Diameter (OD) technology, meaning the fitting goes over the pipe. This design choice results in an unimpeded flow path, leading to a remarkable 25 percent increase in flow and lower friction loss compared to conventional barbed fittings. The result is better performance from your sprinkler heads and a more efficient, water-saving irrigation system.
• Effortless, Tool-Free Removal: Unlike permanent PVC glue joints or destructive barbed fittings, Blu-Lock fittings are completely reusable. The 1/2-inch swing fittings feature a patented quick-release collar mechanism. If you need to adjust, reconfigure, or repair a section of your system, you can remove the fitting by hand without any tools. This reusability not only saves money on parts over the long term but also provides unrivaled flexibility for system modifications and maintenance.

Engineered for Durability: Built to Withstand the Elements

An irrigation system is a long-term investment, and every component must be able to endure harsh underground conditions. Hydro-Rain has engineered the Blu-Lock elbow with heavy-duty construction and premium materials to ensure decades of reliable service.

• Heavy-Duty, UV-Resistant Construction: The body of the fitting is molded from high-impact, UV-resistant ABS plastic, the same durable material used in countless demanding applications. This protects the fitting from degradation due to sun exposure during installation and ensures its structural integrity underground. The internal components consist of a corrosion-proof stainless steel retaining ring and long-lasting EPDM seals, which resist chemicals and maintain their flexibility over time. This combination of materials is designed and tested to guarantee toughness.
• High-Performance Pressure Ratings: This elbow is built to handle the dynamic pressures of residential and light commercial irrigation systems. It is rated for a working pressure of 10 to 80 PSI, covering the vast majority of applications downstream from a valve. To provide an extra margin of safety and demonstrate its robust engineering, the fitting has a burst pressure that exceeds 220 PSI, ensuring it can withstand unexpected pressure surges without failure.

Applications and System Integration

Proper application and compatibility are key to a successful installation. This fitting is designed to be a seamless part of a complete, high-performance irrigation system.

• Ideal Use Cases: The primary function of the BL-406-005 elbow is to create a sharp, 90-degree turn with 1/2" Blu-Lock tubing. It is specifically intended for use in non-constant pressure, valve-out outdoor irrigation connections only. This means it should be installed on lateral lines after the zone control valves, not on the main water line.
• Pipe Compatibility: To ensure a perfect, leak-proof seal, this fitting must be used with the correct pipe. It is designed exclusively for 1/2-inch 80# and 100# SIDR 15 and SIDR 19 HDPE pipe. Using other types or sizes of pipe will result in leaks or connection failure.
• Part of a Complete Ecosystem: The 1/2" elbow is a key component of the fully integrated Hydro-Rain Blu-Lock system. This ecosystem includes a total compatibility of fittings, pipe, manifolds, valves, saddles, and heads, all designed to work together flawlessly. Integrating this elbow with other Blu-Lock components ensures consistent quality, speed, and reliability across your entire irrigation project.
