Festo Straight Threaded-To-Tube Push-In Adaptor, G3/8, 6mm - QSF-3/8-6-B

Make a quick and easy pneumatic connection with this straight adaptor from Festo. Its simple design means you can easily push it into a tube for tool-free and time-saving assembly. The durable fitting is built to withstand the demands of a high-capacity pneumatic system. It features a retaining claw made of steel alloy that's resistant to corrosion and holds tubing firmly without causing any surface damage. This connector is suitable for use in applications with a maximum pressure of up to 14 bar.

• Nitrile-rubber sealing ring creates a tight, leak-free join between the tubing and adaptor
• Safely absorbs pressure surges and vibration for reliability in challenging pneumatic applications
• Nickel-plated brass housing that's resistant to corrosion for increased longevity
• Possible to align after assembly for added convenience

Applications

• Printing industry
• Paper and pulp mills
• Mining and minerals processing

Does this push-in fitting offer a permanent connection with a pipe?

The adaptor makes a secure and leak-free join with a pipe while still being easy to remove. This means you can use it either as a permanent connector or as a temporary fitting in your pneumatic system.
