A Transition Coupler 6″ Insert Coupling in irrigation is a fitting used to connect two different types of pipes, usually from one material to another (e.g., polyethylene (PE) to PVC or aluminum). The insert coupling specifically refers to a barbed or ribbed design that allows for a secure grip inside flexible pipe materials.
After the Layflat hose has been used it expands and becomes challenging to seal around the barb. This 6” insert is designed to accept the stretched-out lay-flat hose.
This coupling can also be used with a new hose with a smaller diameter close to the ends of the couplings. But the diameter is increased towards the center of the coupling so the stretched hose can seal.
