Swing riser fittings are also known as funny pipe fittings. Each fitting has a spiral barb for easy attachment to the swing riser pipe and for a watertight seal. Numerous fittings are available including barbed couplings, barbed tees, barbed by threaded elbows and Marlex street elbows.
These fittings are used with swing riser pipe to make assemblies to be used with underground sprinklers and rotors. They provide flexibility so that rigid PVC pipes or risers do not break when a sprinkler head is run over or stepped on.
