The Graco 17T454 Geka 1/2″ Coupling enables fast, leak-resistant connections for fluid or water lines in compatible Graco systems.
The Graco 17T454 Coupling, Geka 1/2″ is a quick-connect Geka-style fluid coupling designed for use in Graco machines’ plumbing systems. Geka couplings — often recognizable by their claw-style gripping arms — provide a secure and robust connection between hoses, pipes, and accessories with a simple twist and lock action. This coupling supports 1/2″ nominal line connections, making it ideal for water and low-pressure fluid feeds.
Geka connections are popular in industrial spray and mix environments because they allow rapid assembly/disassembly of plumbing, reducing downtime and simplifying cleaning, maintenance, and adjustment. The coupling’s design provides a tight seal and resists accidental disengagement under vibration or movement. Using OEM Graco Geka couplings helps maintain consistent flow and leak-free performance compared to generic or mismatched fittings.
