1/4" Bulkhead Union Push-Fit Connector

The 1/4" Bulkhead Union Push-Fit Connector is designed to allow 1/4" OD tubing to pass securely through panels, equipment housings, or cabinet walls while maintaining a reliable push-fit connection on both sides.

This type of fitting is widely used in water filtration systems, beverage equipment, coffee machines, and drinks dispense installations, where tubing needs to be routed neatly between compartments. The push-fit design allows tubing to be connected quickly without tools, creating a strong and leak-resistant seal.

The threaded bulkhead section passes through a panel or surface and is secured with the locking nut, forming a stable mounting point for the tubing connection.

Why Use a Bulkhead Union?

Bulkhead fittings allow tubing to pass through a solid surface while keeping both sides of the connection secure. Once installed through a panel and tightened with the retaining nut, the fitting provides a stable connection point for push-fit tubing.

This makes them ideal for installations where tubing needs to pass through cabinets, equipment panels, fridge walls, or bar structures.
