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.
Frequently Asked Questions
What materials are these hydraulic fittings available in?
The fittings are available in Carbon Steel, Copper (indicated by the sign "BR"), and Stainless Steel (indicated by the sign "SS").
How is the material indicated in the part number?
Carbon steel fittings use the standard part number (e.g., 15611-08-08). If the fitting is made of stainless steel, the suffix "ss" is added to the end of the number (e.g., 15611-08-08ss).
What thread types are supported in the specification table?
The specification table supports BSP Thread, BSPT Thread, NPT Thread, and JIC Thread, alongside various Flange Sizes.
How does the dash size relate to the metric thread?
As noted in the specifications, the dash of the metric thread corresponds directly with the Outer Diameter (O.D.) of the thread.
What is the relationship between Hose DN and Hose Dash?
Hose DN sizes represent the metric diameter, which maps directly to standardized Hose Dash sizes. For example, Hose DN 3 corresponds to Dash -01, DN 12 corresponds to Dash -08, and DN 64 corresponds to Dash -40.
