SMC KQ2 Series Polybutylene Terephthalate Pneumatic Fitting, 12 mm Push-in 12 mm Push-in

SMC KQ2 Series Pneumatic Fitting, 12mm Connection size A, 12mm Connection size B - KQ2H12-00A

This pneumatic fitting is a push-in straight Union designed for joining two 12mm Air tubes within compressed Air systems. It provides a straightforward connection method for industrial pneumatic circuits and is intended for use where a Compact in-line Union is required. The component is suitable for routine installation in automation and mechanical assemblies where a robust, serviceable tube connector is needed.

Features and Benefits:

• Push-in Interface for Rapid tube installation and removal
  Constructed from polybutylene terephthalate for chemical resistance
  Rated for continuous use up to 10 bar to support pressurised systems
  Operational temperature range from -5°C to 60°C for varied environments
  RoHS-compliant materials to meet Electronic Assembly restrictions

Applications

• Suitable for connecting Air supply lines in automated assembly equipment
  Ideal for linking pneumatic actuators in mechanical systems
  Used with industrial Air tubing 12mm in factory Air distribution networks
  Can be used for maintenance replacements in electrical control panels

How does the connection mechanism work under vibration?

The push-to-connect design secures tubing with an internal collet that grips the tube, maintaining seal integrity under typical industrial vibration levels.

What material qualities affect chemical and wear resistance?

The polybutylene terephthalate body provides dimensional stability and resistance to oils and common industrial fluids, helping reduce degradation over time.

Can it be installed without specialised tools?

Tubing can be inserted and released by hand using the push-in function
Basic tube preparation (clean, square cut) is recommended for reliable sealing.

How should I assess suitability for a humid or warm plant environment?

Check the local ambient temperature against the component’s -5°C to 60°C operating range and verify compatibility of the tubing material with the expected humidity and fluids.

Notes

Models with a -X2 suffix in the Mfr Part No. are copper-free (electroless nickel plated).
