Piston Compact Seal Set P18
DESCRIPTION
Five-piece compact seal P18 is double-acting piston seal P18 is compossed of five elements: main sealing element in NBR or special material on request, two pressure ring in rubber reinforced fabric and two back-up rings in acetal resines POM
Multiple sealing lips on central rubber part provides maximum sealing efficiency and energized both cotton fabric reinforced U-rings when pressure is applied. Effective sealing during vibration and shock loading, excellent sealing effect, no extrusion into sealing gap and simple installation in open groove are obvious advantages.
