Sterling Seal CRG7000I.300.062.300X50 Grafoil Ring Gasket - 3" Pipe Size, 1/16" Thickness, 300# Pressure Class, 3.5" ID, Black Smooth Finish (Pack of 50) - Ideal for High-Temperature Piping Systems, Industrial Valves, and Flange Connections

Flexible graphite’s main attributes: resistance to heat, fire, corrosion and aggressive chemicals make it the most universally applicable sealing solution on the market today Sterling Seal & Supply Style 7000I products provide a tight seal after repeated exposure to the harshest environments Flexible graphite achieves optimal results where other materials fail to a wide range of temperatures including a minimum of [-400 Degrees F (-240 Degrees C), and maximum of +850 Degrees F (+454 Degrees C), (in atmosphere)] [+1200 Degrees F (+650 Degrees C) to +5432 Degrees F (+3000 Degrees C) in continuous reduction or inert media] Seals easily under moderate bolt loads and reduces gasket damage in installation Homogeneous graphite sheets are manufactured from high carbon content (> 98%) natural graphite Ideal material for sealing applications like flange gaskets and valve stuffing boxes EXTERNAL PERFORMANCE TESTS AND APPROVALS *ROTT - Room Temperature Tightness Test *ARLA - Aged Relaxation Leakage Test (TTRL) *HATR - High Temperature Tensile Relaxation Screen Test *HOTT - High Temperature Tightness Test Superior seal ability under low flange loads, high surface conformity to irregularities, unlimited shelf life are a few more major benefits of Style 7000I Style 7000 eliminates potential fluid from binder residue SSI 7000I is an und laminate made with grafoil grade 7000 flexible graphite adhesively bonded to both faces of a 0002” thick flat 316 stainless steel insert Please be advised to wear gloves when handling this product, some styles with inserts can be sharp when cut Sterling Seal & Supply of NJ Style 7000I made of expanded flexible graphite have proven their long-term reliability under extreme operating conditions over the course of many years While maintaining an effective seal, Sterling Seal & Supply Styles 7000, 7000I & 7000T exhibit virtually no creep relaxation As a result, the need for periodic bolt tightening is greatly reduced

You will get maximum performance from our gasket materials when you use our Gasket Installation Procedure. [1] Clean and inspect the flanges, surface or parts that require gasket

[2] Clean or replace your bolts, nuts & washers. Lubricate the bolts, thread, nuts, washers and the underside of the head with Graphite based compound

[3] Flat washers are recommended to assure even distribution of the bolting force. Ensure lubricant doesn’t gasket. Carefully insert the gasket between the mating surfaces

[4] The use of a torque wrench is highly recommended. This assures a longer life and leak free performance. Whether an automotive head gasket or a flange gasket, it should be torqued

[5] Make four even increment passes in a 12-6-3-9 o'clock pattern sequence. The appropriate stress on the gasket material you use is key to its success which varies depending material chosen
