| 💡 Note: The dash of metric thread accords with the O.D of thread. | ||||||||||||||||
Example: Fitting series is 15611, fitting thread is Z 1/2'' X14, Hose bore is 12mm and is made of carbon steel the number is 15611-08-08, if made of stainless steel, the number is 15611-08-08ss.
The part number is structured by combining the fitting series, thread dash size, and hose size. For instance, in "15611-08-08", "15611" is the fitting series, the first "08" indicates the Z 1/2" X14 thread, and the second "08" represents the 12mm (DN12) hose bore.
"BR" stands for Copper/Brass material, and "SS" stands for Stainless Steel. Carbon steel is the standard material and typically has no suffix in the part number, whereas stainless steel adds "ss" to the end (e.g., 15611-08-08ss).
Hose DN (Nominal Diameter in mm) corresponds directly to Dash sizes. For example, DN 3 is Dash -01, DN 12 is Dash -08, and DN 64 is Dash -40. Refer to the hose sizing chart above for the complete conversion mapping.
This specification chart covers BSP (British Standard Pipe) parallel threads, BSPT (British Standard Pipe Taper) threads, NPT (National Pipe Taper) threads, JIC (Joint Industry Council) 37-degree flare threads, and Flange sizes.
According to the technical note in the specification table, the dash size of a metric thread corresponds directly with the Outer Diameter (O.D.) of the thread.
