CNC aluminum vacuum Tee for 1/4" hose. We've all used those black plastic tees that you find at your favorite local auto parts store at 2am, but here is the nicer, cleaner, and permanent solution. We machined this piece with a sharp barb so you slide the hose over and you're done. You don't *need* clamps, but always recommended.
These are sold in packs of 3 only.
