Soft Cut Gaskets 

LoneStar Sealing Technologies supplies a wide range of cut gaskets, from standard flange sizes to large irregular shaped gaskets, in many brand leading materials, from virgin PTFE to compressed non asbestos (CNAF) sheeting and graphite.  Our skilled cutters and state of the art machinery offer a fast, accurate manufacturing service. 

Flange Insulation Kits 

LoneStar Sealing Technologies engineered insulation products can be used to control and confine electrolytic corrosion in almost any piping system. Our insulating materials are manufactured to withstand hydrocarbon exposure, weathering and salt water, while our quality assurance and high production rate mean little or no down time due to electrolysis.  All insulation products are supplied in kit form, complete with the necessary quantities of isolating sleeves, isolation washers and back up washers 

Double Jacketed Gaskets 

As most jacketed gaskets are application specific, precision and attention to detail is crucial. With extensive manufacturing expertise and capabilities, LoneStar Sealing Technologies can ensure the jacketed gaskets we manufacture meet both customer specifications and national and international industry standards. 

Non Asbestos Sheet Material 

LoneStar Sealing Technologies stocks an extensive inventory of non asbestos sheet material that can be used to manufacture gaskets, or supplied by the sheet. Our non asbestos sheet is a compressed material produced from a combination of aramid and other synthetic fibres and bonded with several binders, the most common being nitrile rubber gasket material (NBR).
