Not for: Plumbers needing pressure-rated pipe, or anyone needing large-diameter tube.
What the AI looks for in Brass Tubes
- Outside diameter and wall
- Check both OD and wall thickness; the ID is what matters for sliding fits Telescoping and sleeve fits depend on wall thickness, not just the outer size.
- Telescoping series
- Buy sizes from the same series when tubes must nest Mixing makers rarely gives a sliding fit.
- Not for pressure
- Use rated pipe and fittings for water or gas lines Thin hobby tube is not rated for plumbing pressure.
- Bending
- Anneal or use a tube bender or spring for tight bends Thin-wall tube kinks easily.
Brands that matter
