SMC KQ2 Series Plug Fitting, 4 Connection Size, 32mm Overall Length - KQ2P-04

This plug fitting provides a Compact connection solution for pneumatic installations, designed to seal off or terminate a port within compressed-air systems. It is suitable for use where a secure, quick-engagement Interface is required and operates across a controlled temperature range for industrial environments.

Features and Benefits:

• Operates reliably at pressures up to 1 MPa ensuring system integrity
• Functions between -5°C and 60°C for varied ambient conditions
• One-touch connection type for Rapid installation and removal
• Constructed from polymers and metal for chemical and wear resistance
• Hexagonal socket head enables torque-controlled tightening

Applications

• Suitable for pneumatic systems requiring secure port termination
• Used with metric‑threaded components in machinery assemblies
• Ideal for Compact installations needing quick‑connect fittings
• Can be used for maintenance isolation in production lines
• Used for sealing ports in instrumentation and control panels

What materials compose the body and sealing elements?

The construction combines polypropylene and polybutylene terephthalate with brass components for the contact and thread interfaces.

Which thread standard and connection size does it accept?

It uses a metric thread form and accommodates a 4 mm connection size.

How does the head design assist installation?

The hexagonal socket head permits precise torque application using compatible tools for secure seating.

Are there recognised standards referenced for this component?

The fitting conforms to the referenced JIS B0203 and JIS B0205 standards and meets RoHS requirements.
