Swagelok male connector | tube fitting × male NPT end | 316 stainless steel
A Swagelok two-ferrule tube fitting on one end and a male NPT thread on the other, used to connect to NPT female ports on instruments or valve bodies — a common adapter between tubing and equipment.
The Swagelok male connector has a two-ferrule tube fitting on one end (for the tube) and a male NPT thread on the other (screwed into the threaded port of equipment or a valve). Made of 316 stainless steel, it covers tube size and thread combinations from 1/8 in. to 1 in., and is a common tubing-to-equipment connection in instrument lines. Tell us your tube size and thread specification, and we will match the correct part number.
How Swagelok tube fitting part numbers are built
Swagelok tube fitting part numbers follow a fixed naming rule; once you know it, you can read the specification yourself:
| Code | Meaning | Example |
|---|---|---|
| SS (material) | 316 stainless steel (brass = B) | SS- |
| XXX (tube size) | Tube OD in 1/16 in. (4 = 4/16 in. = 1/4 in.) | 400 = 1/4 in., 600 = 3/8 in. |
| -1- (fitting type) | Male connector (tube fitting × male NPT) | -1- |
| Last digit (thread) | NPT thread in 1/16 in. | 4 = 1/4 in. NPT, 8 = 1/2 in. NPT |
Example: SS-400-1-4 = 316 SS, 1/4 in. tube fitting end × 1/4 in. male NPT end.
Common sizes
| Tube OD | NPT thread | Swagelok part number |
|---|---|---|
| 1/4 in. (6.35 mm) | 1/4 in. NPT | SS-400-1-4 |
| 1/4 in. (6.35 mm) | 1/8 in. NPT | SS-400-1-2 |
| 3/8 in. (9.52 mm) | 1/4 in. NPT | SS-600-1-4 |
| 3/8 in. (9.52 mm) | 3/8 in. NPT | SS-600-1-6 |
| 1/2 in. (12.7 mm) | 1/2 in. NPT | SS-810-1-8 |
Selection service: male connectors cover many tube size and thread combinations from 1/8 in. to 1 in. Please send us your tube OD (mm or in.) and the equipment port thread (NPT / PT / BSPT), and we will confirm the part number and quote.
NPT vs. PT threads: equipment in Taiwan often uses PT threads (JIS / BSPT). PT and NPT threads cannot be interchanged for sealing. Please confirm whether your equipment port is NPT or PT before selection, and tell us when you request a quote.
