1/4" fittings are used for many things in a drip irrigation system.
They can connect 1/4" microtube to other 1/4" microtube to create a distribution system of all microtube. Tees, Elbows, Crosses and connectors allow you to get creative in your system design.
Some 1/4" fittings will have a threaded end which is made for the thicker walled semi rigid poly risers.
All of our 1/4" fittings are a barbed style which means they will fit inside the 1/4" microtube.
They fit any microtube with an I.D. of .140 to .170
Our vinyl 1/4" microtube is a .156 I.D. x .245 O.D.
Our Poly 1/4" microtube is a .170 I.D. x .250 O.D.
