This is a “universal” projectile of medium density, with a
highly porous surface that can remove a vast range of
contaminations. Ideal for tubes in oil pressure systems, air
conditioners and other situations in which it is necessary
to remove dusts, shavings or other production residue stuck
to the internal walls of the tubes. Ideal to be used
together with chemical products with which these projectiles
can be soaked in because of their high absorbent properties
or, for the same reason, for using to dry and remove liquid
or humid residue. Suitable for use on tubes with narrowing
diameter (even up to about 40% of the projectile’s
diameter), T couplings, 90° elbows, etc...
