Pneumatic Fittings and Connectors

Versatile Components for Process Automation

Pneumatic connectors play a vital role in process automation by enabling secure interconnections and precise control functions throughout pneumatic systems. As integral parts of pneumatic circuits, they require careful consideration to ensure compatibility, reliability and optimised performance.

Variety of Connection Options

There are several common types of pneumatic connectors available to suit different applications and installation preferences:

Push-to-Connect Fittings – These quick-connect fittings are a popular choice due to their simplicity and fast installation. Also called “Push-In” fittings, The push-to-connect design provides leak-free joints without tools.

Threaded Connectors – Connectors with industry-standard thread types like BSP are perfect for high-pressure or permanent connections between valves, cylinders and other components.

Quick-Disconnect Couplings – Enabling swift connection and disconnection, quick-disconnect couplings excel for maintenance access or mobile equipment uses.

Barbed Fittings – Barbed fittings securely grip flexible tubing for applications that prefer a non-permanent connection, such as lower pressure circuits.

Selecting the right connector involves consideration of factors like required pressures, component placement, and frequency of disassembly. A variety is needed to satisfy the diversity of connection points within process systems.

Sample Specification Tables

To aid in selecting the right connectors and coils for specific pneumatic applications, example product specification tables are provided below:
