Isolating gaskets may be specified as either 'E' or 'F' type while single, double or one-piece sleeve and washer sets are offered as options for varying degrees of electrical isolation between the flanges. Because the LineBacker™ has very good resistance to creep relaxation², it performs well in heat exchangers, applications with high vibration or excessive thermal cycling. The screened version is the best available product for filtering welding slag, rocks, nuts, bolts and other particulates from traveling downstream and damaging valves, pumps, compressors, etc. The LineBacker™ is an excellent choice for isolating distribution lines and transport lines for gas, oil and water. Maximum hydrotest pressure is 2480 psi and 302Fp> Pressure RatingsĪll ANSI rated flanges to 600#/2,225 psi respectively. Sleeve will be designed to mate with separate isolating washers and will be of a length such that the sleeve extends into one and one-half washer thicknesses on each side of the flange. Most commonly used are Mylar and G10 sleeves accompanied by G10 and zinc plated steel washers. The sleeves and washers offered with the LineBacker ® gasket are completely temperature dependent. The LineBacker ® contains a rectangular sealing element referred to as a “quad-ring.” The quad-ring is used in combination with a unique, engineered groove design and together they provide an effective sealing element that also requires less bolt load than a typical flat gasket. The LineBacker ® gasket is constructed from G10 glass-reinforced epoxy (GRE).
