Properties

Characteristics: 

They are made from environmentally friendly materials such as asbestos-free materials, with graphite with/without metallic inserts. They are manufactured according to customers' specifications in many shapes and sizes or in compliance with DIN and STAS standards. FLAT GASKETS type S-SX for RF, SMF, LMF, STG, LTG flanges

 FLAT GASKETS type S-SX for RF, SMF, LMF, STG, LTG flanges

Applications 

For sealing of pumps, valves, piping and compressors. In case of piping characterized by large variations of heat and pressure and presence of corrosive fluids we recommend manufacturing the gaskets with a protective ring to cover the gasket's surface. 

Materials  

Recommended materials are: stainless steel (1.4541, 1.4571). thickness 0.15 - 0.20 mm, U-bended and tightened in order to become joined with the gasket. Other materials may be used: aluminum, copper, and brass.
