Pack of 6 – Nitto Kohki 600PH 3/4″ Hose HI Cupla
The Nitto Kohki 600PH is a high-performance, industrial-grade quick-connect plug designed for high-flow air lines. As part of the renowned HI CUPLA series, this steel hose barb (PH Type) is engineered for maximum durability and reliability in factory environments, making it an essential component for connecting pneumatic tools to main air supplies.
This bulk pack of 6 ensures you have standardized, interchangeable fittings across your entire workshop or production line.
Key Features
Exceptional Durability: Constructed from heat-treated steel with a chrome-plated finish, providing superior strength and resistance to wear, even in heavy-duty industrial applications.
High-Flow Design: Specifically sized for 3/4″ hoses, allowing for high-volume air delivery to power larger pneumatic equipment without significant pressure drops.
One-Way Shut-Off: Designed as a “plug” for use with HI CUPLA sockets. When disconnected, the socket side automatically shuts off while the plug side remains open.
Interchangeability: Fully compatible with other HI CUPLA 400, 600, and 800 series models, allowing you to mix and match with different end configurations (Threaded, Nut Cupla, etc.).
Hose Barb Connection: Features a secure hose nipple design, perfect for permanent or semi-permanent attachment to rubber or PVC air hoses using standard hose clamps.

Installation Tip
For a leak-free and safe connection with 3/4″ hoses, always use a high-quality worm-gear or crimp-style hose clamp. Because these are high-flow fittings, ensuring the hose is fully seated over the barbs before tightening the clamp will prevent accidental blow-outs under pressure.
