Insert fittings are durable fittings that are used in irrigation applications for hose hookup. Insert fittings are barbed on one end so the fitting can grip the hose when inserted to establish a firm connection with the hose. A clamp is also recommended to use in this application to ensure the joint stays connected in pressure applications. Inserts are molded in many different fashions to fit any hose application that you may have. Straight, tees, 90, and crosses are just some of the ways inserts are manufactured to fit your special need.
