PTFE Steel Lined Gaskets are highly recommended in nearly all applications that require the sealing of metallic flange joints in high temperature and/or high pressure conditions to prevent cold flow which can lead to joint failure.
Reinforced with perforated stainless steel inserts (AISI 304) PTFE Steel-lined Gaskets have properties that are far superior and more cost effective than other gasket designs.
Designed to meet the needs of many different piping applications, they are ideal whenever a non-metallic gasket must be used. Unaffected by even the most aggressive chemicals, PTFE Steel Lined Gaskets combine all the properties of PTFE together with exceptional sealability.
Engineered with a perforated stainless steel insert that is mesh molded in PTFE material, these gaskets exhibit exceptional creep resistance for the reliable sealing of steel piping flanges.
PTFE lined gaskets that meet the standards according to EN 1514-1 and ASME B16.21 standards, are made of Virgin PTFE and full PTFE calcium fluoride, recommended for the Chemical application of fluorine and to improve the deformation properties of compressive strength.
