SMC KQ2 Series Pneumatic Fitting, 4mm Connection size A, 1/8 inches Connection size B - KQ2K04-01AS

This pneumatic fitting connects a 4mm tube to a 1/8 in threaded port in pneumatic systems, providing a Compact 45° male elbow connection for directional routing. It is intended for use where a male-threaded R1/8 appliance is required and where compatibility with common tubing materials is important for automation and industrial assemblies.

Features and Benefits:

• Electroless nickel-plated brass construction for corrosion resistance
• Supports vacuum to full pressure range for versatile operation
• Accepts FEP, PFA, nylon and polyurethane tubes for broad compatibility
• Rated to 10 bar for high-pressure pneumatic tasks
• Operates between -5°C and 60°C for varied environments

Applications

• Suitable for pneumatic tubing runs in automated assembly lines
• Ideal for control cabinets requiring space-saving elbow fittings
• Used with pneumatic actuators in electrical panel work
• Can be used for laboratory vacuum manifold connections
• Used for compressed-air distribution in mechanical workshops

Which thread standard is provided for panel or component mating?

It uses an R-standard male thread sized to 1/8 in to match BSP tapered ports.

What materials are suitable for the push-to-connect end?

The connector accepts FEP, PFA, nylon and polyurethane tubing types without modification.

How does the fitting behave under temperature extremes?

It is specified to operate reliably down to -5°C and up to 60°C without affecting sealing performance.

Is the fitting suitable for vacuum applications?

Yes, it is specified to function across vacuum levels up to its full pressure capability.
