Parker Legris Liquifit 4mm - 6mm Tube-to-Tube Connector
Overview
The Parker Legris LIQUIfit® 4mm–6mm tube-to-tube connector is a straight push-in fitting designed for inert gas applications in low-pressure pneumatic systems.
This bio-sourced polymer connector simplifies installation in applications requiring quick, reliable tube connections without tools or threads. The stainless steel gripping ring secures tubing firmly whilst the EPDM seal ensures dependable performance across a wide temperature range from 14 °F to 95 °C. Rated to 232 psi maximum operating pressure and capable of withstanding continuous vacuum down to 755 mm-Hg, this fitting handles demanding process air, instrument air, and inert gas distribution with minimal pressure drop. The straight configuration makes it ideal for inline connections where space is constrained or frequent disconnections are necessary.
Supplied in packs of ten, these connectors serve food and beverage processing, industrial manufacturing equipment, and pneumatic automation systems where hygiene, reliability, and ease of maintenance are priorities.
