SMC TJ Series

SMC Series TJ Pneumatic Fitting, 4mm Tube Connection Size, 60°C Maximum Operating Temperature - TJ-0425

This pneumatic fitting provides a compact, push-in connection for pneumatic tubing in industrial control systems. It is designed to join flexible tubes to pneumatic systems where a robust material combination and moderate temperature endurance are required. The fitting supports straightforward tube insertion and retention while being suited to applications that demand a small connection footprint.

Features and Benefits:

• Push-in tube connector 4mm enables fast tool-free installation
  Polyurethane construction offers abrasion resistance for tubing
  303 stainless-steel elements resist corrosion in contact areas
  Rated for operation up to 60°C permits use in warm environments
  Compact TJ series push-in fitting form reduces panel space

Applications

• Suitable for pneumatic control lines in automation cabinets
  Used with 4mm tubing in pick-and-place equipment
  Ideal for supply lines to pneumatic actuators and valves
  Can be used for instrument Air connections in production cells
  Used for retrofit of existing 4mm push-in systems in factories

What tube size does it accept for direct connection?

It accepts 4mm tubing designed for push-in retention.

Which materials contact the tube and the system?

Polyurethane interfaces with the tubing while 303 stainless-steel forms the wear and seal-contact components.

How does temperature affect operational use?

Continuous operation is supported up to 60°C, beyond which material performance may be compromised.

Is assembly required for installation into a pneumatic circuit?

Installation involves inserting the tube into the push-fit connector without additional tools.

What advantage does the Compact form offer in system layouts?

The reduced footprint allows denser routing of 4mm Air lines and saves space in confined panels.
