The JET-SET® 1207 Compression Fitting comes standard on our JET-SET® 1000-MS Nozzle Assembly connecting the 900 Nozzle and the 803HD Nylon Tubing. The 1207 Compression Fitting is also used in our Manifold System. Simply undo the fitting by losing the nuts and replace with the new one. Once it is all secure again you're ready to spray.
