SMC KQ2 Series Plug Fitting, 8 Connection Size, 1 Mpa Maximum Operating Pressure - KQ2P-08

This plug fitting is a pneumatic closure piece designed to terminate or seal tubing connections in compressed-air systems. It is manufactured from engineering plastics and metal to function within typical industrial temperature ranges and to be compatible with different thread and sealing methods. The fitting is intended for applications where a rapid push-in connection and secure threaded seal are required.

Features and Benefits:

• Maximum operating pressure 1MPa delivers stable system shut-off
• Operating range -5°C to 60°C supports varied ambient conditions
• Constructed from polybutylene terephthalate for chemical resistance
• Polypropylene components reduce weight and corrosion risk
• Brass sealing parts provide durable threaded engagement
• Hexagonal socket head enables secure tightening with tools

Applications

• Suitable for pneumatic test rigs requiring temporary seals
• Ideal for service panels with mixed metric and UNF threads
• Used with NPT or RC threaded ports in maintenance tasks
• Suitable for one-touch tubing installations in workshops
• Used for systems requiring gasket seal or thread sealant

What thread types can be accommodated with this fitting?

It is compatible with multiple thread forms including UNF, NPT and RC to suit different port standards.

How is leak prevention achieved at threaded joints?

Sealing is provided by a gasket arrangement and the option to apply thread sealant on the metallic engagement surfaces.

Which materials are in contact with the medium and why?

The medium interfaces with polybutylene terephthalate and polypropylene components for chemical resistance, and brass at the threaded seal for mechanical durability.

What tool access is required to install the fitting?

A hexagonal socket driver is used to tighten the head to the required torque for a reliable seal.
