Small-Diameter, Thin-Wall Fuse Tubes with Tight Tolerances
Thin-wall vulcanized fiber and epoxy tubes for compact cylindrical links. Compact links need thin walls and small diameters held to tight ID/OD. We roll and finish these sections and check wall concentricity so the element seats correctly. Tell us the smallest ID, the wall and the tolerance; we will confirm whether rolling or machining gives the better result for your volume.

Applications by industry
- Small-diameter fuse link bodies for instrument and control circuits
- Thin-wall barrels for low-current HRC and gG links
- Precision fuse bodies for OEM aftermarket assemblies
- Glass-tube replacement barrels run to tight OD tolerance
- Wire-in-tube protection sleeves in test equipment
- Custom link bodies machined with precision end-cap shoulders
Why vulcanized fiber for this application
Small bores with thin walls call for a material that cuts clean without delaminating at the edge. Vulcanized fibre machines on standard lathes to a repeatable thin wall, which is why it is the default for compact, low-current link bodies.
Dimensional tolerance tightens as wall thins; stock must be moisture-conditioned or bores grow in humid climates. Confirm torque limits on press-fit end caps.
Standards: ASTM D2491 (vulcanized fiber), IEC 60269, UL 248.
Feature and remaining-wall review
For Small-Diameter, Thin-Wall Fuse Tubes with Tight Tolerances, ID and OD are ground or turned and the CNC handles knurling, threading, slotting and cutting to drawing. Review of feature depth, edge distance and remaining wall happens pre-quotation, with capability confirmed against your drawing rather than a general tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request
