O-ring gasket Elastic Tankpak 6756

elastomericelastomercomposite

Features EagleBurgmann Elastic Tankpak 6756 is an excellent gasket for sealing transport containers for chemicals or solvents. The core is made from a hollow elastomeric material (EPDM) wrapped in PTFE foil, thus guaranteeing optimum chemical resistance for the entire seal. The polypropylene middle layer primarily acts as a cushion and buffer, and it is first wrapped with PTFE foil. The entire seal is then over-braided with PTFE yarn, fixing it firmly to the rest of the material composite. Advantages Outstanding recovery curve Suitable for repeated opening and closing of container covers Universal chemical resistance Enormous inherent strength Optimized abrasion resistance Reusable Operating range Pressure: p = 0,7 bar Temperature Continuous operation: t = -50 ... +100 °C Continuous operation 6756/TH: t = -50 °C ... +250°C Chemical resistance: pH = 0 ... 14 Resistant to acids, alkalis, oils, organic solvents and liquid and powdered chemicals. Standards and approvals DNV, USCG (PO2/1,2 Butylenoxid) Germanischer Lloyd Recommended applications Industries Chemical industry Shipbuilding Variants 6756/TG (EPDM core/Polypropylene/PTFE) 6756/TH (Elastomer core/Glass fibre/PTFE) Notes For rectangular cross-sections, the maximum width/height ratio should ideally not exceed 3:2. The surface pressure applied to the seal must be evenly distributed around the edge, and must be applied in small increments by attaching as many toggles or clamps as necessary.
