DIN 3852-2 Form E Vs. ISO 1179-2 Form E

Do you know the difference between DIN 3852-2 From E and ISO 1179-2 Form E. Today this blog will explain everything to make you fully understand.

Actually, DIN 3852-2 Form E and ISO 1179-2 Form E are the same thing for BSPP thread port and BSPP stud ends. The DIN 3852-E pressure connection thread standard has been invalid since 2012.  The standard that has been valid since then for pipe threads (e.g. for G ¼ A) is DIN EN ISO 1179-2: “Connections for general use and fluid power – Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing…”

At QC Hydraulics, since the end of 2015, we have started to refer to the valid ISO 1179-2 standard for new BSP fittings with captive seal. However, we also make a reference to the old standard, “DIN 3852-2 Form E”, as we are not sure how well the ISO 1179 standard is already known to our clients. For existing products, we will gradually clean up the information, as we want to do our part to ensure that the valid DIN EN ISO 1179-2 standard is established.

QC Hydraulics is a leading manufacturer of stainless steel hydraulic fittings meeting ISO 1179-2 standard. Please contact us for more details if interested.
