Features & Benefits

Built for Speed: Cut Installation Time in Half

• Patented "Push-and-Go" Design: This fitting is 100% tool-free and chemical-free. Simply push the 1/2" Blu-Lock swing pipe into the adapter for an instant, permanent connection. This intuitive method slashes installation and repair time by 50% or more compared to conventional PVC or barb fittings.
• Guaranteed Leak-Proof Connection: Each fitting houses a patented system of stainless steel teeth that grip the pipe with incredible force, while a heavy-duty EPDM O-ring creates a watertight seal. This robust construction allows you to bury the connection with total confidence, preventing costly water waste and callbacks.
• Removable & Reusable: Plans can change. Unlike solvent-welded fittings that are permanent, this 1/2" Blu-Lock adapter features a patented quick-release collar. This innovative design allows for easy, tool-free removal and repositioning, offering valuable flexibility for any project.

Built for Green: A Smarter, Eco-Friendly Choice

• A Safer, Chemical-Free Installation: By eliminating the need for hazardous PVC primers and solvent cements, the Blu-Lock system protects the health of both the installer and the surrounding environment. It's the clean, modern approach to irrigation.
• Optimized Water Flow: Blu-Lock fittings use an innovative Outside Diameter (OD) technology that provides a full, unimpeded flow path. This superior design minimizes friction loss and can increase water flow by up to 25% compared to restrictive insert-style fittings, resulting in better sprinkler performance and enhanced water efficiency.
• An Environmentally Conscious System: This adapter is a key part of the Blu-Lock ecosystem, which utilizes environmentally friendly, recyclable HDPE pipe as a more flexible and durable alternative to traditional PVC.

Ideal Applications & Use Cases

The Hydro-Rain BL-436-101 is the perfect fitting for creating a secure transition from 1/2" Blu-Lock swing pipe to any component with a standard 3/4" female pipe thread (FPT) inlet. It is essential for a variety of common irrigation tasks:

• Connecting flexible swing pipe assemblies to larger pop-up rotors and high-flow spray bodies.
• Attaching swing pipe to 3/4" threaded risers for precise placement of larger sprinkler heads.
• Upgrading from smaller spray heads to larger rotors without needing to re-pipe the entire line.
• Building robust, custom swing joints to protect high-value sprinkler heads from damage.
• Transitioning from a 1/2" Blu-Lock tubing run to a manifold or valve with 3/4" threaded ports.
