Quick disconnects are (as the name would imply) connectors that can be connected and disconnected quickly. These seal very well (no drips at all) and support liquid flow in either direction. Mates with the male end to form a locking seal. The female end comes with a spring loaded cover (that must be pulled back when connecting or disconnecting), ball bearings that lock into the male groove, and a food grade o-ring that creates the seal.
Use these together with our Stainless steel 1/2" NPT female x 1/2" barb fitting fitting to finish the ends of your hoses.
We opted to use two pieces as adding the barbed fitting makes the solid ends of the hose a bit heavier (better when sparging into the boil kettle and filling fermenters) and a bit longer (easier to grip).
Note: Always purchase the male and female ends from the same manufacturer to ensure proper fit. Improper fit can lead to leaks (fit too loose) or damaged o-rings / o-rings that get dislodged (fit too tight).
