Sealing of ball ground joints in laboratory and pilot plant.
Ball sleeve with gripping ring and sealing rings on the outside made of a half-plastic PTFE-formulation in standard sizes for joint grease-free ball ground joints with standard steel clip locking, for gas- and liquid-conducting piping as well as for high-vacuum-tight joints (leakage rate: <1 x 0,01 mbar x l x s/1). A special grip ring on top of the sleeve allows easy removing and reassembling many times. Sealing rings on the outside of the sleeves and a low friction coefficient prevent sticking of the ground joints. This reduces the danger of breaking and injury. Chemical-resistant, free of leachable components and biocompatible. Temperature-loadable from -200 to +250 °C, sterilizable with all commonly used methods.
