Material Specification
Fittings consist of bodies made from engineering plastic or brass, 'O' rings from Nitrile rubber, and collets from acetal copolymer with stainless steel teeth.

Applications
Fittings are designed for air use and should be clean and undamaged. They are not suitable for explosive gases, fuels, or central heating systems.

Installation Recommendations
Consider pressure ratings and installation guidelines during design. Pipes should be supported at least every 800mm, and supports should not be closer than 25mm from the fitting's end. Fittings should connect after the air receiver, not directly to a compressor. Pressure testing is advised post-installation.

Side Loads
Fittings should not bear excessive side loads or be used as support brackets. Adequate support for tubing and fittings is necessary.

Super Speedfit Push-in Fittings
These fittings are for miniature pneumatics, offering quick and secure tube connections, easy disconnection, and reusability without tools.

Metric Size Fittings
SuperThread fittings work with various metal thread forms without sealant, providing superior flow and compact design.

Banjo Flow Control
These controls, installed directly into cylinder ports, regulate pneumatic cylinder speed, offering precise adjustment for soft metal and plastic tubing.

Technical Specifications
Temperature range: 5ºC - 70ºC. Working pressure: 0.5 Bar to 10 Bar. Materials include Acetal Copolymer, Brass, Stainless Steel, and Nitrile. Air supply should be filtered to 50 microns.
