1 Grafoil GTS Graphite Thread Sealantis a patented, high-purity paste madefrom a combination of nuclear gradegraphite and a nuclear quality petroleumbased carrier. It has all the characteristicsrequired for long-life performance, evenunder the most severe lot of Grafoil GTS thread sealant paste ispackaged in 125gm nuclear Grade polyethylene squeezable tubes to protect against propertiesShelf Life2-year minimum from date of first useStorage Temperature< = 38oC (100oF)Pipe Size Limitation< = 2 ( OD close fitting thread joints)TGA AnalysisWeight loss begins at about 125oC (255oF) with 6%weight loss at 200oC (390oF). Grafoil GTS maintainsits seal up to 635oC (1175oF).As the company s products are usedfor a multiplicity of purposes and asthe company has no control overthe method of their applications oruse, the company excludes allconditions or warranties, expressedor implied by statute or otherwise,as to their products and/or theirfitness for any particular technical co-operation betweenthe company and the customer isgiven for customers assistance only,and without liability on the part ofthe / Specification Sheet Grafoil Grade GTSS erviceGTS Paste is made to seal small diameter,close tolerance threaded pipe joints incritical service applications to 635OC(1175OF) and 16 MPa (2300psi)*.

2 Grafoil GTS Thread Sealant Paste can also be used as an effective boltlubricant or anti seize compound, having outperformed many conventionallubricants under test. Because GTS threadsealant paste does not harden or curewith time or temperature, joints sealedwith GTS paste will be easy to dissembleeven after years of high-temperatureservice.*For service conditions over 16 MPa Flexitallicrecommends that application testing is / ComplianceGTS Thread Sealant Paste can be certifiedto meet many nuclear specificationsbecause of its purity and thermal in a form that permits easyapplication, GTS thread sealant paste is an ideal replacement for Teflon Threadsealant tape and other conventionalthread sealant materials in critical hightemperature and high pressure serviceapplications. The purity level of GTS thread sealantpaste allows it to meet the stringentcertification requirements of the nuclearpower generation industry such as theGeneral Electric non-metallic materialspecification D50YP12 Rev of GTS Pipe Thread Sealant Paste WeightLoss vs Temperature10090807060504030201000 100 200 300 400 500 600 700 800 900 Temperature (oC)Weight %Directions for clean threadedsurfaces prior to tube well (for best results, remove cap,squeeze out air, replace captightly, then knead well) paste evenly and fill threads assemble andtighten the threaded cap tightly after is ready forimmediate 21.
