Product Overview

This 55mm OD clear inner striped 50mm acrylic tube is designed for LED lighting and optical diffusion. This rigid PMMA pipe is made from 100% virgin PMMA and features internal ribs that help spread light evenly and reduce glare from LED hot spots. The tube is extruded with a 55 mm outer diameter, an inner diameter of 44 mm and a wall thickness of 5.5 mm. It delivers great optical clarity, weather resistance, and long-term durability without yellowing over time. It is an ideal choice for linear LED fixtures, decorative lighting, and structural housings. We provide custom length cutting services, tailored wall thicknesses, and custom internal rib patterns to fit your specific project requirements.

Frequently asked questions

Yes. This typical profile is extruded from high clarity PMMA (Acrylic) However, if your project requires a higher impact resistance or flame-retardant performance (UL94-V0) we can also produce it from Polycarbonate (PC).

Yes, indeed. We have existing standard tooling for outer diameter 25 mm, 40 mm and 55 mm. Since custom plastic extrusion is our core business, any other custom outer diameters, wall thicknesses, or inner rib profiles can be rapidly developed with low-cost custom tooling based on your engineering drawings.

Sure. We offer secondary processing in house, from length cutting to CNC drilling, punching and end-cap fitting to give ready-to-install components.

The minimum order quantity for this 55 mm OD tube is 300 meters. As a B2B OEM custom extrusion manufacturer, we focus on bulk and custom production runs rather than single-piece retail.

Key Applications

  • Linear LED Lighting Fixtures: The inner ribs are great for linear pendant lights and architectural strip housings to smooth out LED diode hotspots and provide even light output.
  • Commercial & Retail Displays: Widely used in decorative lighting, show lighting and illuminated signs requiring durable, crystal clear optical tubing with anti-glare qualities.
  • Architectural Accent & Facade Illumination: Ideal for indoor and outdoor accent lighting applications requiring long lasting UV protection and weatherability without yellowing.
  • Industrial & Optical Tube Housings: Provide protective covers for sensitive light bars, sensor housings or specialty lighting components where strong light transmission and structural stiffness is required.
