Overview
The Parker Legris LF3000 4mm Blanking Plug is a push-to-connect fitting designed to seal open ports in vacuum and low-pressure pneumatic systems.
This plug provides a simple, reliable method for closing unused connection points in compressed air and vacuum circuits, eliminating the need for threaded caps or complex sealing arrangements. The technical polymer body delivers excellent chemical resistance whilst remaining lightweight, making it ideal for applications where durability and ease of maintenance are priorities. With a 4mm bore and rated for vacuum pressures up to 755 mm-Hg, the fitting operates dependably across a temperature range of −20 °C to 80 °C, accommodating both indoor and outdoor installations.
The straight tube stem configuration ensures secure insertion into standard LF3000 receptacles without additional tools or adapters. Supplied in convenient boxes of 50 units, this blanking plug reduces inventory complexity for technicians managing modular pneumatic systems.
Widely specified across off-road machinery, industrial automation, and process air applications, this fitting supports efficient system design and rapid component changeover.
