Metric Hydraulic Fitting Identification: Step-by-Step Guide
Common metric thread pitches include 0.5mm, 0.75mm, 1.0mm, 1.5mm, and 2.0mm. For hydraulic fittings, pitches like 1.0mm, 1.5mm, and 2.0mm are frequently encountered. Standard Sizes: Use reference charts to cross-check the pitch size. These charts list standard thread pitches for various fitting types and sizes, helping confirm your measurements.

After measuring the diameter of your threads, determine their spacing in threads per inch. In the case of metric connections, measure the thread-to-thread distances. To get an accurate value, ensure that the thread pitch gauge is fitting well on the threads. Record the values and compare your measurements with the figures provided in this guide.

The DIN male 60° internal cone seat will mate with DKL/DKM female universal 24°/60° cone fittings up to and including size M26 and DKM female 60° cone fittings from size M30 up.
Metric Thread Chart: A Guide to The Right Size - QC Hydraulics
Metric thread callouts are fundamentally different because the thread pitch is specified instead of threads per inch or per mm. The thread pitch is the distance between each thread in mm. For example, an M10x1.5 (coarse) thread has a 1.5mm pitch, …

In writing, you can identify metric threads by a capital “M” plus an indication of their nominal outside diameter (ex. M22 x 1.5). Lastly, when measuring pitch size make sure you’re using a metric pitch gauge.
Metric Bite Type Fittings are called out by tube size (in millimeters) i.e. 20mm Tube (S20), while Metric Port Fittings are called out by Thread O.D. and Thread Pitch (in millimeters) i.e. 30x2.0 or 30x1.5.

Various types of fitting allow the designer to change the flow of the fluid, to split the flow of the fluid, or to elevate the lines. Below we’ve compiled a hydraulic fittings size chart describing some of the more common fitting sizes and types currently in use by pipe fitters and other professionals. National Pipe Tapered Fuel (NPTF)
tube size (mm) which will attach to the given thread. For example, a DIN 24° light male in size M18x1.5 will attach to a metric standpipe measuring 12mm outside diameter. The same female thread size in a DIN heavy pattern will connect to a 10mm O.D. standpipe. Ferrules are installed as shown, with the longer taper facing the male thread.
