304 stainless steel capillary tubing for general precision use
304 stainless steel capillary tubing is a practical choice for many general instrument, sensor, sleeve, guide tube and small component requirements. Dongguan Yefa reviews standard and custom size inquiries by OD, ID, wall thickness, cut length, tolerance, surface condition, quantity, and application.
Key points for buyers and engineers
- Choose 304 for general corrosion resistance, stable forming and broad industrial use when the application does not require the added corrosion performance of 316L.
- Separate raw tube requirements from processed component requirements such as cutting, deburring, polishing, drilling, slots, or assembly features.
- Use a dimensioned size table when several similar OD and ID combinations must be quoted together.
- Confirm packing and labeling rules to prevent small-diameter or thin-wall tubes from bending, scratching, or mixing during shipment.
Technical facts to compare
When 304 is the economical engineering choice
304 is widely used where general corrosion resistance, availability and manufacturing economy are more important than maximum resistance to chlorides or aggressive chemicals. Buyers should compare the actual operating environment instead of choosing the grade from price alone.
How to prepare a 304 capillary tube RFQ
Mark all critical dimensions and tell the supplier whether the tube will be used as raw material or as a finished component. A drawing is especially useful when the tube needs controlled ends, holes, slots, bends, special cleaning, or individual packing.
- Nominal and critical dimensions
- Material and hardness or condition if specified
- Surface and end-face requirement
- Inspection method and documentation
- Prototype and production quantities

FAQ
Is 304 suitable for precision capillary tubes?
Yes. 304 is commonly used for general precision tubing when its corrosion resistance and material properties match the operating environment.
What is the difference between 304 and 304L?
304L has lower carbon content and is often considered when welding or sensitization risk matters. Use the grade stated in the drawing or material specification.
Can 304 capillary tubes be cut to short lengths?
Yes, but the RFQ should define length tolerance, end-face condition, burr control, bore pass-through, quantity, and packing expectations.
RFQ information to prepare
For supplier review, prepare material grade, OD, ID, wall thickness, cut length, tolerance, quantity, surface finish, application, drawing files, inspection requirements, packing notes, and destination country.
