Festo KD4 Series Pneumatic Quick Connect Coupling, 12 Bar Maximum Operating Pressure, 1/4 inch Thread Size - KD4-1/4-I
This pneumatic quick-connect coupling provides a secure, quick-disconnect interface for compressed air systems. Manufactured by Festo, it is designed as a female coupling socket with a G-thread form to join 1/4 inch threaded connections. Suited to typical workshop and industrial pneumatic installations, the connector operates across a practical temperature range for routine compressed air applications.
Features and Benefits:
• 12 bar maximum operating pressure delivers robust system performance
• Brass construction reduces corrosion and supports longevity
• Nickel-plated finish enhances surface durability in service
• Compatible with G-thread fittings for standardised connections
• Operational from -10°C to 60°C for varied ambient conditions

What material characteristics affect wear resistance?
The body is brass with a nickel-plated surface to improve surface hardness and resistance to mechanical wear.
What operating pressure limits should be observed?
The coupling is rated for service up to 12 bar
systems should not exceed this pressure.
Which thread type must mating components use?
Mating parts require a female-compatible G-thread interface sized for 1/4 inch connections.
What temperature boundaries define safe handling and storage?
The unit is specified for use between -10°C and 60°C, so storage and operation should remain within these limits.
