Hose/Tube Cleaning Projectile For 1.42 Inch ID

Fit is based on hose or tube inside diameter. UC36 is meant for a 1.42 inch I.D. line (listed I.D. is 1.4173 in). For I.D. sizes 2 inches or less, the projectile outside diameter is typically about 20% larger than the I.D. so it wipes the inside as it travels.

Anywhere from 85 to 150 PSI will get the job done. Below 85 and you're not likely to get a clean pass through, and you don't want to push past 150 either. Most shop air setups in that range will work fine as long as your supply stays steady through the shot.
