The projectile cleans by being pressed against the internal surface of the hose, tube or pipe. This pressure is achieved, as the projectile is approximately 20% to 30% larger than the internal diameter of the hose, tube or pipe. For instance, a 50mm (2") projectile is recommended for a 38mm (1-1/2") hose.

Ultra Clean: Hose, tube, pipe and assemblies. Removes fine particles of loose contamination and can also be used for product purging.
Abrasive: Hose, tube or pipe with build up of contamination, surface rust or scale.
Grinding: Straight lengths of tube or pipe with greater build up of contamination, surface rust or scale.
NOTE: An Ultra Clean projectile should always be used after an abrasive or grinding projectile to insure cleanliness.

Individual circumstances may require a smaller or larger projectile. If the projectile is too large it will not leave the nozzle and if it is too small it will not clean effectively. The enormous variety in the types of couplings available today could also mean in some circumstances that the recommended size is inappropriate. When cleaning assemblies, a reduction in projectile size may be appropriate, as all the recommendations are based on the most commonly used coupling sizes.
