Flange-to-Tube Adapters & Flanged Tube Fittings
Connect a flanged piping system to tube-fitting connections. Send your drawing and operating requirements so we can review the appropriate configuration.
Flange adapters
Technical reference data below is provided in English. Final dimensions, pressure-temperature ratings, material and standard compliance must be confirmed for the selected part.
| Feature | Reference information |
|---|---|
| Connection function | Transition from flanged piping to a tube-fitting system without a threaded pipe joint or welding at the transition. |
| Flange standard families | ASME, DIN, EN and JIS flange types; specify the exact standard, size, facing and pressure designation for confirmation. |
| Construction | One-piece, integrally machined forged body. |
| Tube-fitting end connections | Up to 50 mm and 2 in. tube sizes, depending on configuration. These are tube sizes, not flange nominal sizes. |
Flanged tube-fitting features
| Feature | Reference information |
|---|---|
| Flange standard families | ASME, DIN, EN and JIS. Confirm the exact standard and configuration for the selected part. |
| Flange sizes and pressure ratings | Model-specific; numerical ranges were not provided in the supplied reference. Request a dimensioned drawing and pressure-temperature rating. |
| Facing options | Flat face, raised face, ring-type joint (RTJ), and tongue-and-groove, subject to configuration confirmation. |
| Material | 316 stainless steel as standard; Alloy 20, Alloy 400, Alloy 600 and Alloy C-276 listed as optional materials, subject to availability. |
| Installation feature | Wrench flats to facilitate tube-fitting installation. |
| Initial installation inspection | The supplied reference mentions a Swagelok gap inspection gauge. Confirm gauge applicability with the fitting manufacturer for the exact fitting and size before use; this is not a blanket compatibility or interchangeability claim. |
Reference features describe the product range, not a single configuration combining every option.
