All BX energized gaskets manufactured to API 6A incorporate a pressure passage hole, allowing equalization of pressure between grooves.

Style TME R being the standard ring joint gasket, manufactured in accordance to ASME B16.20 and API 6A. Available in Oval and Octagonal shape which are both interchangeable within octagonal type grooved flanges.

Style TME RX is used in octagonal type grooved flanges. Allowing interchangeability with the joints to improve sealing efficiency. Pressure passage holes are added to RX 82 through RX 91 allowing equalization of pressure.

Kammprofile Gaskets are manufactured utilising a precision machined serrated insert sealing element with V-like cut grooves designed to entrap a sealing compound to create many individual seals across the face of a flange. The sealing element can be used stand alone in the case of a tongue and grove application or can incorporate a centering ring, either fixed or loose depending on the specific application.

Spiral Wound Gaskets come in a number of different styles which offer outstanding sealing capabilities within flanges. Withstands high pressures, heat and seals against almost every known corrosive and toxic media.

Precision engineered gaskets and seals are critical components used in both subsea and surface applications. Predominately, these parts are manufactured from all types of steels, stainless steels and high nickel alloys and are manufactured to very strict tolerances. LoneStar manufactures your precision gasket requirements on CNC machine tools in the US, UK and India. Currently, we operate over 20 different machine tools, ranging from small diameter bar-fed machines to large horizontal CNC lathes.

Jacketed Gaskets - for shell and tube type exchangers. Consisting of a soft filler embedded in a metallic material, jacketed gaskets provide both resilience and strength for a number of shell and tube type applications. Most jacketed gaskets are application specific and therefore precision and attention to detail is crucial during production. With extensive manufacturing expertise and capabilities, LoneStar is able to ensure the jacketed gaskets we manufacture meet customer specifications along with those set by national and international industry standards.
