Ball Lock Check Valve Gas Disconnect 1/4" MFL

Enhance your kegging system with the Ball Lock Check Valved Gas Disconnect, 1/4" MFL (Part Number: DC40 27-4000-00), a premium gas-side connector designed for Cornelius or Firestone Ball Lock kegs. Engineered in Germany and assembled in the USA, this disconnect blends precision craftsmanship with practical innovation. Its internal check valve allows CO2 to flow into your keg while preventing liquid backflow, protecting your regulator and gas lines from damage—ideal for homebrewers who demand reliability.

Featuring a 1/4" MFL (threaded) connection, this disconnect pairs effortlessly with swivel nuts for versatile hose compatibility: use a 1/4" MFL to 1/4" barb swivel nut for 3/16" or 1/4" gas tubing, or a 1/4" MFL to 5/16" barb swivel nut for 5/16" hose. Installation is quick and secure, requiring no extra tools beyond a hose clamp. NSF certified, made with FDA-approved materials, and meeting SK-approved European standards, it ensures food-grade safety and top-tier quality. Plus, it connects directly to portable CO2 chargers for carbonation on the go.

Say goodbye to beer in your gas lines and enjoy a cleaner, more efficient brew day with this German-engineered disconnect. Whether you’re carbonating your first keg or maintaining a pro-level draft system, the DC40 27-4000-00 delivers leak-free performance and peace of mind every time.

This is an NSF Certified product.
