Thermoseal / Klinger - Beater Add - RG-N120

RG-N120 is a reinforced cellulose gasket material with a nitrile butadiene rubber binder and inorganic fillers that provides a very good crush resistance at high flange pressures. Continuous roll lengths allow efficient and economical fabrication with high speed die cutting equipment. RG-N120 seals oil, water, and coolants well in applications such as small engine intake and cover gaskets, automotive water pump and throttle body gaskets and similar applications with intermittent operating temperatures up to 350° F (177° C).
