DURAN® spherical ground joint cups, inch size, KS 19/7

DURAN® spherical ground joint cup, inch size,S 19/7 DURAN® spherical ground joints to DIN 12244 and 12264 are used to make flexible connections of up to 15° - depending on the size of the joint. From an angle > 5°, a reduction in tightness must be expected. The nominal size is composed of the nominal diameter of the spherical ground joint and, if applicable, the inside diameter of the pipe. As a general rule, ground joints with ground joint grease or PTFE sleeves should be used. Spherical ground joint clamps with locking screw are the perfect complement to secure the spherical ground joint. Special features and advantages: According to DIN 12244 and 12264 Pliable, flexible connections of up to 15° can be realized depending on the ground joint size (angle ? 5° tightness reduced) Better detachability due to higher flexibility of the ground joint The nominal size describes the nominal diameter of the spherical ground joint.
