GRAPHITE GASKET -PUTG
Spec.TU 5728-006-93978201-2008
PUTG gaskets are intended for sealing in standard types of mating surfaces (smooth, “male-female”, “tongue-and-groove”) of fixed connections, and also for sealing threaded connections and other types of connections (joints) according to the customer design documentation.
PUTG gaskets are a good alternative to the gaskets made of paronites and foreign asbestos-free leakproofing materials; they demonstrate the best parameters as to operating temperatures, compressibility/ restorability, chemical inertness, capability to seal defective flanges.
