Sketch Description
SPETOMET® MPL® 10
spetomet_mpl_10

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
spetomet_mpl_11

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.

SPETOMET® MPL® 12
spetomet_mpl_12

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
spetomet_mpl_121

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
spetomet_mpl_20

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
spetomet_mpl_21

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
spetomet_mpl_23

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
spetomet_mpl_23_i

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
spetomet_mpl_24

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
spetomet_mpl_26

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
spetomet_mpl_29

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.
