Ground breaking valve seat insert technology as used by OE supplier Kolbenschmidt AG in Germany.
GOLD series designed for both petrol and diesel engines that are naturally aspirated or turbo charged.
DIAMOND series designed for extreme applications such as LPG and propane fuels.
Modern engines put much higher levels of thermal and mechanical stress on valve seats inserts. To handle the more severe conditions with these new generation engines, OEM is equipping them with high tech sintered valve seat inserts. The normal cast iron valve seat inserts will no longer adequately withstand the demands of this new engine environment. This is the reason why Durabond developed high tech sintered powder metal valve seat inserts in two specifications to suit any engine.
