DIN 2353 vs ISO 8434-1 Standards

Date:May 28, 2019

DIN 2353 and ISO 8434-1 is the same standard for metric hydraulic fittings, with cutting ring type fittings, also called bite type fittings, and compression tube fittings. The important thing is to inter-changeable for each other. Same 24 cone connector end, same assembly with nut, cutting ring.

The differences are between DIN 2353 and ISO 8434-1 as follows:


Standards:

DIN 2353:2013 Non-soldering compression fittings with cutting ring - Complete fittings and survey.

DIN EN ISO 8434-1 Metallic tube connections for fluid power and general use – Part 1: 24 degree cone connectors (ISO 8434-1:2007) English version of DIN EN ISO 8434-1:2008-02


Scopes of shape and dimensions:

DIN 2353:  provides a survey on the shape and dimensions of fittings composed of standardized fitting parts and which are not contained in DIN EN ISO 8434-1.


ISO 8434-1 specifies the general and dimensional requirements for 24° cone connectors,  using cutting ring and O-ring seal cone (referred to as DKO) suitable for use with ferrous and non-ferrous tubes,  with outside diameters from 4 mm to 42mm inclusive.


Port standards:

DIN 2353: standard applies for complete non-soldering compression fittings with cutting ring designed with stud ends according to DIN 3852-1 and DIN 3852-2.


ISO 8434-1  are intended for the connection of plain end tubes and hose fittings to ports in accordance with ISO 6149-1, ISO 1179-1 and ISO 9974-1. (See ISO 12151-2 for related hose fitting specification.)



DIN 2353:  standard is intended for selection and determination of the size of complete fittings. This standard has been prepared by Working Committee NA 082-00-07 AA "Rohrverschraubungen" ("Tube connections") at the Piping and Boiler Plant Standards Committee (NARD).


ISO 8434-1  connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in this part of ISO 8434.
