Frequently Asked Questions
How do I identify the material of a fitting based on its part number?
Standard part numbers represent Carbon Steel fittings. For Stainless Steel fittings, the suffix "ss" is added to the end of the standard part number (for example, 15611-08-08 becomes 15611-08-08ss).
What material options and signs are available for these fittings?
These fittings are available in Carbon Steel (indicated by standard designation), Copper (indicated by the sign "BR"), and Stainless Steel (indicated by the sign "SS").
How does the Hose DN size relate to the Hose Dash size?
Hose DN sizes correspond to specific Hose Dash numbers. For example, a Hose DN of 3 corresponds to a Hose Dash of -01, a Hose DN of 12 corresponds to a Hose Dash of -08, and a Hose DN of 64 corresponds to a Hose Dash of -40.
Which thread types are supported under this specification?
This specification supports BSP (British Standard Pipe), BSPT (British Standard Pipe Taper), NPT (National Pipe Taper), and JIC (Joint Industry Council) threads.
How is the dash size determined for metric threads?
According to the specification notes, the dash size of the metric thread directly accords with the Outer Diameter (O.D.) of the thread.
