Triple Piston Scaler

T3 Triple Piston Scaler with Bent Handle. Piston scalers are used for many different surface preparation projects. They can be used to remove heavy rust, scale, paint or industrial coatings from metal surfaces. They can also be used to rough concrete prior to resurfacing. The pistons used for these applications range from standard steel to carbide tipped or REXALLOY which is a solid cobalt alloy. Please note, solid cobalt alloy pistons TX00151 should NOT be used for concrete surface preparations. It has been found that silica in concrete causes heat buildup in the REXALLOY pistons which in turn causes the pistons to wear more rapidly. REXALLOY pistons should ONLY by used on metal surfaces and primarily for their spark resistance. REXALLOY pistons are spark resistant as per paramenters used by OSHA in reference to US Naval Report No. NGF-T-1-157, NAVORD 5205, agreeing that in.ANYin. spark produced from impact with the REXALLOY part will be a cold spark not conductive of ignition in hazardous envornments. They are non-magnetic, rust proof and carbide hard. Features: Rugged steel body, Lever operated snap handle, Optional brass air cock valve available, Variety of pistons available. Applications: Removing rust and paint, Removing cement from steel, Roughing cement, Piston scalers can be used in areas that standard model scalers will not fit.
