Pneumatic Straight Tube-to-Tube Adaptors

Pneumatic technology uses pressured gas to drive some sort of mechanical motion. The most common gas used in pneumatic technology is dry air. The air must be dry as moisture has different compressive qualities. Pneumatic technology is very similar to hydraulic technology, however the fluid used to drive the motion here is always a liquid.

Pneumatic systems are operated using a central pneumatic device (such as an air motor or compressor) and utilise manual or automatic solenoid valves to control the airflow around the system.

Pneumatic systems contain many components, pneumatic straight tube to tube adaptors being one example.

What are pneumatic straight tube to tube adaptors used for?

Pneumatic straight tube-to-tube adaptors are used to connect two tubes together. Straight adapters do not change the tube direction and most work with a range of materials such as nylon, polyurethane and polyamide.

Types of pneumatic straight tube to tube adaptors

Pneumatic straight tube-to-tube adaptors come in a variety of diameters, sizes, and materials. Some are nickel-plated brass and others feature glass-filled nylon.
