MASTER-PUR polyester, polyurethane technical hoses are abrasion resistant. Hoses vary in wall thickness up to 2mm for super-heavy grade and are ideal for application in conveying food and pharmaceutical ingredients as well as finished products through pneumatic conveying systems. Diameters range from 2" to 16", depending upon series. All hoses feature spiral construction that welds a protective polyurethane-coated wire to FDA-acceptable food grade hose wall. Integral ground wire dissipates any static electricity in hose for safe operation over a very long service life. Masterduct, Inc. 5235 Ted Street Houston, TX, 77040
