Parker Legris Liquifit 4mm - 4mm Equal Bulkhead Union
Overview
The Parker Legris LIQUIfit® 4mm Equal Bulkhead Union is a push-in tube connector designed for beverage dispensing and low-pressure fluid applications. This fitting enables reliable, leak-free connections in compact spaces where traditional threaded fittings are impractical.
The bulkhead union configuration allows you to mount tubing directly onto a panel or manifold, making it ideal for modular system layouts in food and beverage equipment. Its bio-based polymer body keeps the fitting lightweight whilst the stainless steel gripping ring ensures consistent tube retention across pressure cycles. With a maximum operating pressure of 232 psi and continuous vacuum capability to 755 mm-Hg, the fitting handles both pressurised and suction applications with equal competence. The EPDM seal material resists beverage fluids and operates reliably between 14 °F and 203 °F, covering most industrial temperature ranges.
The 4 mm tube connections and 13 mm hex size make installation and removal straightforward without special tools. Supplied in boxes of 10, this fitting serves food and beverage production lines, automated beverage systems, and general low-pressure pneumatic manufacturing equipment.
