SPETOMET^® MPL^® 10 gaskets are made of a metal core and thin layers on; it is used as a basic type of gaskets for narrow flange surfaces or as a bar of multiedge or spiral wound gaskets. MPL^® 10 metal only style is also available.

SPETOMET^® MPL^® 11 gasket from corrugated metal face, used for less severe temperatures where flanges are ligtly loaded; corrugation increases conformability of the gasket; gasket can be galvanized; in rare cases it is applied in this construction, most frequently it is a metal core of SPETOMET^® MPL^® 12 style.

Profile SPETOMET^® MPL^® 12AM is the gasket forecasted for hot-gas and / or hot-blast gasket used for iron and steel industry. MPL^® 12AM is constructed from the main inner steel ring which is covered by two MPL12 corrugated gaskets with graphite layers and then wrapped with graphite impregnated fibreglass material.

SPETOMET^® MPL^® 12 gasket is manufactured from corrugated steel rings covered on both sides with soft sealing material, e.g. graphite or expanded PTFE, corrugation increases conformability of the gasket whereas layers improve the tightness of the sealed joint - also with the ceramic layers for the furnace covers and dust pipelines; applied in tongue and groove, male and female flanges, for flat flanges also as MPL^® 12 Z style.

SPETOMET^® MPL^® 121 compared to MPL^® 12 features better sealability, blowout resistance and physiological safety; metal eyelet mosty from 1.4571 stainless steel; available also MPL^® 121 Z style with optimized width of the gasket’s sealing area.

SPETOMET^® MPL^® 20 flat gasket in single metal jacket with an opening is used for narrow flanges; manufactured from metal sheet, which encapsulates soft filler; such profile protects the soft edge of the gasket’s material; most of gaskets of this style are made from copper and its width is less than 6 mm; for larger cross sections MPL^® 23 style is recommended.

SPETOMET^® MPL^® 21 gasket is similar to MPL^® 20 but the metal jacket is overlapped and closes the soft filler; maximum width of the gasket is also 6 mm.

SPETOMET^® MPL^® 23 are double jacketed gaskets made from two pieces of metal and soft filler. This gasket is the most commonly used profile for heat exchangers and other vessels: the two piece metal construction gives extra rigidity which allows for large diameters; may be manufactured in various shapes and dimensions; also the profile with centring ring MPL^® 23 Z.

SPETOMET^® MPL^® 23 I gasket has additional metal part inside the filler stabilizing the profile (prevents excessive, transverse deformation of the gasket); the metal inside inreases gasket’s strength, by improving its resistance to stress; thickness above 3,2 mm is recommended for this profile in order to apply the metal part; this is a proper solution also for the gaskets with the desired end thickness.

SPETOMET^® MPL^® 24 compared to MPL^® 23 style has features increased resistance characteristics, recommended for gasket thickness oper 3,2 mm and in case of flat flanges or male and female flanges; for flat flanges also the style MPL^® 24 Z with the centring ring is available.

SPETOMET^® MPL^® 26 gasket in the corrugated metal jacket; it has better conformability due to reduced contact area (corrugations), recommended for gasket’s width over 13 mm.

SPETOMET^® MPL^® 29 is the gasket composed of corrugated jacket and the metal corrugated filler; better temperature resistance, maximum temperature depending only on the metal properties; used also in applications where due to chemical attack soft filler cannot be applied; features also high resistance to compression.
