SKA Universal Seamless Stainless-Steel Tube - 6-25 mm OD, 1.4404/1.4435
- Seamless Stainless Steel Tube
- Suitable for compression fittings and couplings
- ⌀ 6-30 mm and 1/4" - 1 1/2"
- Max pressure 350 bar
SKA Universal Seamless Stainless-Steel Tube - 6-25 mm OD, 1.4404/1.4435
- The SKA Universal Seamless Stainless-Steel Tube is purpose-engineered for use with compression couplings and other tube-fitting systems.
- Manufactured from 1.4404 / 1.4435 stainless steel, it combines precisely controlled hardness and surface roughness with PE-capped ends to arrive clean, damage-free and ready for assembly.
- Supplied in convenient 2 m lengths (6 m available on request) and stocked in all common metric and fractional sizes from 6 mm / 6.35 mm up to 25 mm / 25.40 mm, the SKA tube lets fabricators, installers and operators standardise on a single tube family for multiple hydrogen-service duties while cutting inventory, floor-space and handling time.
Key features
- Compression-coupling ready – hardness and finish tailored for reliable bite-type and ferrule fittings
- Universal stock programme – one tube family covers Ø 6 mm (¼″) to Ø 25 mm (1″)
- Tight surface-finish control – outer Ra ≤ 0.8 µm; inner Ra ≤ 0.8 µm for OD ≥ 10 mm
- Clean, protected delivery – PE caps fitted to both ends prevent contamination and transit damage
- Lean logistics – 2 m shipping length saves warehouse space and simplifies site handling (6 m option)
- Process-safe – consistent properties minimise the risk of assembly errors or mismatched tubing
- Cost-efficient – priced comparable to standard-quality tube, yet eliminates multiple special grades
