FAQ
Q1: What is the maximum continuous operating temperature of FR4 fiberglass tubes?
A: The standard FR4 tube can operate continuously at temperatures up to 140°C (284°F). Short-term exposure up to 180°C is acceptable, but prolonged use above 140°C may affect long-term mechanical and electrical performance.

Q2: Can FR4 tubes be machined using standard metalworking tools?
A: Yes. FR4 fiberglass tubes can be easily cut, drilled, milled, turned, and tapped using carbide-tipped or diamond-coated tools. We recommend using dust extraction during machining due to fine particulate generation.

Q4: How do I select the right wall thickness and diameter for my project?
A: The choice depends on your mechanical load, voltage rating, and space constraints. Thicker walls offer higher dielectric strength and rigidity, while thinner walls save weight and cost. Our engineering team can help you optimize dimensions based on your application—just share your design requirements!

Q5: Are FR4 tubes suitable for outdoor or humid environments?
A: Yes. FR4 has very low moisture absorption (<0.2%), making it stable in humid conditions. However, for prolonged outdoor exposure to UV radiation, we recommend protective coatings or alternative materials like GPO-3 if UV degradation is a concern.

Q6: Do you offer samples before bulk ordering?
A: Absolutely. We provide free or low-cost samples (shipping may apply) so you can evaluate material quality, color, and machinability before placing a full order.
