Technical Overview

The series features premium push-in / push-fit /one-touch pneumatic fittings engineered for seamless connection in pneumatic and automation sectors. Designed with a highly compact structure, these fittings allow for unlimited make and re-make connections without requiring any specialized tools. This ensure a trouble-free and reliable joint every time. Both the composite and full brass versions are fully interchangeable and compatible with industry-leading brands like SMC. This makes them an exceptional choice for upgrading or maintaining existing automated setups and robotics.

 

Engineered to withstand diverse operational demands, the series offers distinctive specifications and premium materials for varied industrial settings. The PBT composite models handle working pressures from 0 to 1000kPa, while the heavy-duty nickel-plated brass variants manage higher pressures ranging from 0 to 1800kPa. Operating flawlessly within a temperature range of -20°C to +80°C, the construction incorporates a robust collet and a Nitrile O-Ring for superior sealing. The product line supports both imperial and metric tubing, with a comprehensive thread selection that includes BSP, NPT, and Metric systems to ensure a perfect fit across global machinery standards.

 

Optimized for low-pressure pneumatic applications and factory automation, these fittings are strictly designed for use with non-metallic tubing. They provide secure, leak-free grip on flexible lines such as Nylon and Poly tubes, though they are not compatible with metal tubes. It is critical to note that this series is dedicated exclusively to pneumatic systems and must not be used in any hydraulic applications. With their high compatibility with major brands like SMC, these fittings serve as a cost-effective, high-performance alternative for modern manufacturing lines.
