In the 24°-Weld nipple fitting the pipe welding side is adjusted depending on the diameter and wall thickness of the pipe dimensions. The seal between the fitting and the welding nipple is an O-ring, which is mounted on the 24 ° cone of the welding nipple. By tightening a nut  the Weld Nipple with O-ring is pressed into the 24 ° cone of the fitting.

This series of fittings, in which the connection dimensions of the fitting bodies are identical to the sealing cone, flared or cutting ring connection, are particularly suitable for applications with extreme pressure peaks, pressure surges and vibrations in the system. Thanks to the soft seal, the welding cone fitting guarantees maximum tightness, especially in the gas sector.
