Chips are small, hard, randomly-shaped abrasive particles which will loosen scale and rust from tank walls, thereby augmenting the action of solvent chemicals to remove/suspend internal contamination. This material can be used in steel or aluminum tanks and with various adjunct solvents EXCEPT TANK ACID which will attack the chips and produce excessive gassing. Aluminum oxide has been successfully used for tank tumbling for 40 years. Use 25-35 lbs. per tank.

Special, small stainless brushes for removing those stubborn deposits on the very bottom of dive tanks. Each brush screws onto a 3 - foot aluminum rod which fits into a 3/8" electric drill. Each unit comes with the brush, 36" extender rod and a plastic guide sleeve to augment insertion through tank necks. Heavier, stiffer wire from bottom flash rust or other deposits in STEEL tanks.

This cylindrically shaped brass brush is ideally suited for cleaning the 1/2" NGT threads of older scuba cylinders or those that are 7/8"-14 UNF on "high-pressure" steels. Brass, a non-sparking metal, is excellent for O2 applications because any metal particles accidentally left behind by the brush would be benign in nature.

A small, cone-shaped stainless steel brush which can be used in any electric drill to safely and quickly clean tank neck threads and the O-ring groove.

Cylindrical, plastic handled brush with fine stainless steel wire for cleaning 1/2" NGT and DIN dive tank neck threads without harm to the threading. Brush wire diameter measures approximately 13/16". Order #43020 for 3/4"-14 NPS tank thread sizes.

Chips are cylindrical, cast resin pellets with a computer-designed shape for specific cutting activity. Each pellet (5/32" OD x 5/16" long) contains an abrasive agent which gives a very precise, predictable cleaning action. More tolerant of acid than aluminum oxide, ceramics are very useful for tumbling aluminum tanks or for oxygen-cleaning operations. Use 25 - 35 lbs. per tank.
