Festo KS3 Series Pneumatic Quick Connect Coupling, 12 Bar Maximum Operating Pressure, 1/4 inch Thread Size - KS3-1/4-I


This pneumatic quick-connect coupling provides a straightforward method for linking compressed-air lines in industrial settings. Designed for compatibility with G-thread fittings, it serves as a plug connection for pneumatic systems where robust material choice and a protective surface finish are required. The component functions across a moderate temperature range and is suitable for routine assembly and maintenance of air-powered equipment.

Features and Benefits:


• Operates safely up to 12 bar for pressurised system use
• Female G thread offers secure screw-in connection
• Brass construction delivers mechanical durability and corrosion resistance
• Nickel-plated finish improves surface wear and chemical resilience
• Functional between -10°C and 60°C for varied workplace climates

Applications


• Suitable for workshop compressed-air distribution systems
• Ideal for pneumatic tool hook-ups in manufacturing lines
• Used with assembly jigs requiring quick instrument changes
• Can be used for maintenance of plant air manifolds
• Used for temporary pressure testing of pneumatic circuits

What thread size should I prepare on mating components?


Prepare a 1/4 inch G threaded receptacle to match the female connection for correct engagement.

How does the material selection affect long-term service in industrial atmospheres?


Brass resists galling and provides dimensional stability under cyclic loading, while the nickel plating reduces surface oxidation in humid or mildly corrosive environments.

What temperature extremes will impact connection integrity?


The connector maintains functionality down to -10°C and up to 60°C

exposures beyond these limits may affect sealing and metal tolerances.

Is the product compliant with environmental substance restrictions?


It meets RoHS requirements limiting certain hazardous materials in electrical and electronic equipment assemblies.
