AVK rubber-metAl FlANGe GAsKet 79 ePDm rubber, drop-shaped "KGs-s" design 003 WATER AVK flange gaskets with steel insert are suitable for flanges made of steel, stainless steel, glassfibre reinforced plastic, PP, PVC, PE and for coated flanges. We offer two different basic designs, the straight KGS design and the drop-shaped KGS-S design, which both are available in EPDM and NBR rubber. WASTE WATER GAS Product description: EPDM flange gasket in drop-shaped KGS-S design for water and wastewater applications to max. 100° C (short term up to 130° C) standards: WATER GAS • Designed according to DIN EN 1514-1 SUPPLY SUPPLY WASTEWATER SEWAGE FIRE FIGHTING tests/Approvals: • Approved according to KTW D1/D2, EN 681-1, DVGW/ W270, ACS, WRC/WRAS and Ö-Norm FIRE PROTECTION Features: • Vulcanised rubber gasket in EPDM shore 70 with lenticular shape and rounded edges • Moulded drop-shape at the inside of the gasket protects against corrosion and pressurized volumes at the sealing area, and offers optimal sealing properties in case of flange unevenness as well as at lowest tightening torques. The shape also makes the gasket suitable for flanges made of thermoplastic material. • Inside a vulcanised steel ring offering a good absorption of surface pressure • Outer diameter self-centering to the inner diameter of the screw holes • Suitable for applications requiring good ozone-, ageing- and weatering resistance • The gaskets are resistant to water and dilutions of salts, diluted acids and alkalines, polar media such as alcohol and ketone, washing agents, hydraulic media based on water-glycol and hydraulic media based on phosporic esters. Resistance to mentioned media should be confirmed by AVK before installation. The gaskets are not resistant against aliphatic, aromatic and chlorinated hydrocarbons or highly oxidising acids.
