NITO 1/2" Coupler

Product Description

NITO 1/2" Coupler with Stop – With 1/2" and 3/4" Female Threads
This NITO 1/2" Coupler with stop function and dual-thread connection (1/2" and 3/4" female threads) is a versatile solution for efficient and controlled fluid handling in both professional systems. As part of NITO’s original coupling series – known for quality, reliability, and long service life – this product delivers flexibility and operational safety in one compact unit.

The integrated stop function ensures that water flow is automatically shut off when the coupling is disconnected. This helps prevent water waste and allows the user to easily switch accessories, hoses, or tools without having to shut off the main supply. Thanks to the dual female thread design, the coupling body can be used in systems with either 1/2" or 3/4" threads – without the need for extra adapters. This increases flexibility and reduces the number of components in your setup.

Manufactured from chrome-plated brass, the coupling body features durable components such as a stainless-steel spring and hardened locking balls, ensuring long-lasting performance – even at working pressures up to 25 bar. The Nitrile (NBR) seals provide effective resistance to both water and oil, and Viton seals are available for applications with specific temperature or chemical requirements.

Key Benefits of the NITO Coupling Body with Stop and Dual Thread:
• Automatic shut-off when disconnected – prevents water waste
• Fits both 1/2" and 3/4" female threads
• High wear resistance and corrosion protection – chrome-plated brass
• Quick, tool-free connection and disconnection

At NITO, we’ve spent more than 125 years designing and manufacturing couplings that ensure secure, stable connections – between components, people, and systems. When you choose this coupling body, you’re choosing a product built for reliable performance, day after day – with flexibility engineered into the solution.
