The spinner brushes consist of a polyurethane foam tip mounted on a polypropylene plastic handle. The foam tip resists shredding and lint generation. Both the foam tip and handle have excellent chemical and solvent resistance, allowing use with a wide range of common solvents. The brush, having a generous 6-inch length, can easily access the entire length of the inner bore of a Varian style spinner turbine. The foam tip is 1/4 inch in diameter and nearly an inch long, providing excellent contact and cleaning action within the slightly smaller bore of 5mm spinner turbines.
