Note the listing’s two rounded outside-diameter expressions: 5/16 inch equals 0.3125 inch, while .312 inch is slightly smaller. Treat these as nominal listing dimensions, not a precision tolerance. If another part must fit inside or around the tube, measure the material you receive or confirm the current manufacturer specification before designing a close fit.

Check fit before choosing tube #230

Start with the project drawing or the part that the tube must meet. Confirm whether the required measurement is outside diameter, inside diameter, wall thickness or length; they describe different dimensions. The store record does not provide the inside diameter, wall thickness, tolerance or a confirmed telescoping fit with another tube or rod. Do not infer those details from the outside diameter alone.

For an HO-scale project, compare the actual profile and scale appearance against the reference. A 5/16-inch tube may suit a large hollow detail, but it is not automatically an HO-scale dimension or a structural support. Dry-fit a short sample before cutting several matching pieces.

Cutting and finishing hollow styrene

  1. Mark the required length around the tube so the cut stays square.
  2. Support the tube while cutting to reduce crushing or splitting.
  3. Use a suitable fine saw or hobby cutting method and follow its safety instructions.
  4. Square and lightly smooth the end, then test-fit it before repeating the cut.
  5. Use an adhesive and finish labeled as compatible with styrene; test on scrap first.

The listing is for styrene tube material. It does not include adhesive, paint, primer, tools or project-specific fittings. This hobby stock is not a pressure-rated or safety-rated tube; do not use it for plumbing, fuel, compressed air or load-bearing applications.
