DURAN® spherical ground joint bowls, ground jointless, KS 13/5

DURAN® spherical ground cup, polished, S 13/5 The ground cup version of DURAN® spherical ground cups seals only via the sealing ring. Basically, 2 versions of the sealing rings are available: - FEP-coated silicone rings - Sealing rings made of VITON The nominal size is composed of the nominal diameter of the spherical ground joint and, if necessary, the inside diameter of the tube diameter. This variant also allows flexible connections, these are in the angle range of 10-15°. Special features and advantages: Pliable, flexible connections of up to 15° can be realized depending on the ground joint size (angle ? 5° tightness reduced) Grease-free operation possible A tight seal is made possible by the use of an additional sealing ring. The nominal size describes the nominal diameter of the spherical ground joint. Non-self-supporting Glassware for further processing Application: For the production of grease-free, flexible connections (alignment in 360° possible), shoring in glass apparatus and equipment
