Review on Anderson Metals 57001 0404 Fitting Adapter by Dan Bobbert

I was wrong in assuming that "1/4" notch" is on the 1/ 4" plastic irrigation line branded KORAM The KORAM "1/4" hose has an OD of 0.25" and an ID of 0.167". The OD of the hose burr of this part is beginning to stretch to fit this barb, even after soaking in hot water.My guess is that there must be some other, larger ID, or more flexible tubing for this pin to work with.EDIT: I managed to get it working bring after cheating by turning the outside edge of the burr on the lathe.
