If you just finished your new project and after airing things up hear that pssssshhhhh noise, guess what? Woops, this is what you forgot to add. When installing a new elbow, stainless line, macroline, quick disconnect or any occasion of working with pneumatic parts, you'll always need Teflon tape to create a seamless air tight seal to avoid any leaks. The 1/2" wide Teflon tape on these rolls have a 21 grade tensile strength, is manufacturered to a T.27730A military specification and should last you quite some time for any other pressure related endeavors you may run across in the future.
