Stainless 304 capillary tubes drawn to fine bores with tight wall control. Capillary flow depends on bore consistency along the whole length, so we gauge bore and wall on every lot, not just the first and last piece.
Function and Design
The 304 capillary tube is small in the bill of materials and large in the warranty claim when it goes wrong. The 304 capillary tube is produced to print, with the features that carry function inspected first.
Key Features
- No plating to scratch: the stainless 304 capillary tube handles washdown, humidity and process media directly.
- Small orders are welcome – prove the part, then scale.
- Deburred, cleaned and packed – ready for assembly without rework.
- Material: stainless steel (304 / 316) as the running stock for 304 capillary tube work, with certificates available on request.
- Process: tube drawing and turning for the 304 capillary tube, wall held to the agreed band.
- Finish: The 304 capillary tube finish is set by the drawing: natural, plated or coated, with masking where required.
- Size: 304 capillary tube dimensions follow the print, feature positions held to the drawing tolerances.
- Custom: Custom production of the 304 capillary tube to print, MOQ set by the drawing rather than a catalogue.
Applications
It earns its place in automotive sensor stems, industrial gauge tubing, medical and food-grade devices.
Our Production Advantage
The 304 capillary tube is small in the bill of materials and large in the warranty claim when it goes wrong. We hold the critical 304 capillary tube dimensions with gauges and first-article checks rather than relying on the drawing alone.
