Puncture connecters example
Puncture connecters are used to connect 1/4" tubing to 1/2" supply tubing for adding emitters.
Simply grasp the tubing firmly in one hand and press the sharp end of the puncture connecter through the tubing. There are tools available to make this easier, but I find them to be unnecessary.
Attach the 1/4" tubing for supplying an emitter, bubbler or micro spray.
