For hoses/tubes/pipes 3/16" (4.8mm) to 5/8" (15.8mm) I.D. Goodway's Coupling Projectiles are specially formulated for use with hose, tube or pipe that have couplings installed. These soft, dense packed foam projectiles are for use with any Goodway pneumatic hose cleaning gun. As a projectile is shot, it is compressed, loosening and propelling dirt and deposits through the hose, tube or pipe. Projectiles are oversized to ensure proper compression for maximum cleaning action. Match to your hose/tube I.D. for proper sizing.
