Parker Legris Liquifit 4mm Blanking Plug
Overview
The Parker Legris LIQUIfit® 4mm Blanking Plug is a straight push-to-connect fitting designed for food processing and healthcare applications requiring secure tube termination in low-pressure pneumatic systems.
This blanking plug provides reliable sealing of 4mm tube connections without requiring a separate seal component, making it ideal for applications where tubing lines need to be capped off or isolated during operation or maintenance. The bio-based polymer construction delivers robust performance across food and beverage production environments whilst maintaining compatibility with neutral gases. Operating safely between 14°F and 203°F, the fitting withstands continuous working pressures up to 232 psi and maintains vacuum integrity to 755mm-Hg, making it suitable for both positive pressure and vacuum applications in instrument air systems.
Supplied in convenient boxes of ten units, these plugs integrate seamlessly into existing LIQUIfit® tube networks. This fitting serves food processing facilities, pharmaceutical manufacturers, healthcare equipment builders, and process automation systems requiring hygienic, efficient pneumatic connections.
