Description

QC Hydraulics stainless steel DIN 2353 tube fittings meets DIN 2353 & ISO 8434-1 standards. DIN stands for “Deutsches Institut für Normung”, meaning “German institute for Standardization”.

DIN Metric and BSPP tube fittings are the most common thread styles in Europe. DIN type tube fittings conform to the requirements of ISO 8434-1, DIN 2353, and DIN EN 3850 standards. This ensures the compatible with leading brands of fittings. Such as, Parker, Eaton, DK-LOK, Superlok…

DIN 2353 fittings consist of a body, cutting ring (ferrule) and nut. On assembly, the two cutting edges of the ring (ferrule) bite into the outer surface of the tube ensuring the necessary holding power and seal for high operating pressures and extreme vibration.
