Swivel Fittings: Kuru-Lin

Effortlessly Solving Every Issue — The Essential Swivel Joint for Drone Firefighting

Issue

During drone takeoff and landing, hoses tend to kink.
Additionally, reaction forces during water discharge can destabilize the drone’s attitude control.

Feature

A fitting that moves freely: 45° in all directions and 360° along its axis.
This mechanism eliminates hose twisting and enables precise, stable firefighting operations.

The Developer's Vision

At the 2024 National Firefighting Skills Competition, we conducted on‑site observation. Seeing that most fire engines were equipped with competitor-made swivel joints was extremely frustrating.
That moment sparked the development of our own swivel joint. Through many twists and turns, it was ultimately adopted for drone applications.
This fitting embodies the support, effort, and passion of many people.
