SMC Polypropylene, Polybutylene Terephthalate Plug Fitting

SMC Series KQ Plug Fitting, 4mm Connection Size, 60°C Maximum Operating Temperature - KQP-04

This plug fitting provides a Compact connection solution for fluid systems, designed to join tubing and threaded ports in low-pressure pneumatic or fluid applications. It operates across a moderate temperature range and is constructed from engineered thermoplastics to suit environments requiring both pressurised connection and temperature resilience.

Features and Benefits:

• 1 MPa maximum operating pressure delivers controlled system containment
  -5°C minimum operating temperature supports chilled environments
  60°C maximum operating temperature allows warm-process compatibility
  4 mm connection size permits small-bore tubing integration
  One-touch connection type enables Rapid tube insertion and removal
  Hexagonal socket head facilitates secure spanner installation

Applications

• Suitable for Compact pneumatic control manifolds
  Ideal for laboratory fluid-distribution racks
  Used with small-bore instrumentation tubing
  Can be used for confined-space maintenance connections
  Used for threaded-port termination in process lines

What materials are used in the construction?

The body combines polypropylene with polybutylene terephthalate components to balance chemical resistance and dimensional stability.

How does the connection Interface accommodate threaded ports?

It provides a male-to-female threaded arrangement with a hexagonal socket head to allow torqued engagement into mating threads.

What makes it suitable for quick servicing in assemblies?

The one-touch fitting mechanism permits fast insertion and release of tubing without requiring additional tools.

Which pressure class should systems be rated to when incorporating this component?

Systems should be designed to operate at or below 1 MPa to match the fitting’s maximum pressure capability.
