DIN Tube Fittings Introduction

The origin of DIN tube fitting is from Germany Ermeto in 1930’s, DIN is Deutschen Instituts für Normung, later International Standard Organization(ISO) edit the ISO 8434-1 with the design of 24 degree cone connectors, is equal to part of DIN 2353 standards. It is also called “cutting ring fittings”, “flareless bite type fittings” and “Ermeto EO fittings”

Overview shapes Of DIN Tube Fittings

Tube to tube connector is made of these shapes, from hex bar or forging body as follows:
