Smooth brass tube without thread 20mm diameter

Smooth brass cylindrical tube for lamps

The smooth brass cylindrical tube with a 20 mm diameter is an essential component for those looking to create, restore, or customise lighting fixtures with a professional and durable finish. Its threadless design and completely hollow interior make it the ideal solution for concealing connections and electrical wiring, while offering a clean and tidy aesthetic structure. Thanks to its straight form, also known as a straight arm, this tube easily integrates into floor lamps, table lamps, or decorative projects where a sturdy and visually neutral metal piece is required.

Composition and material quality

Entirely made of brass, this tube stands out for its excellent resistance, stability, and long-term performance. Brass provides structural rigidity, corrosion protection, and a warm, elegant decorative finish. Its smooth surface enhances the aesthetic integration of the assembly and allows the component to function both visibly and hidden within the lamp. Although it does not have its own thread, it is designed to work with threaded rods and compatible fittings, ensuring a secure and perfectly aligned assembly.

Compatibility and applications

This brass tube is compatible with a wide variety of decorative lighting systems. Thanks to its hollow interior, it can accommodate standard electrical wiring of up to 2x1.5 mm², making it a highly versatile piece for lamp restoration, repair, or manufacturing projects. Its use is particularly suitable for floor and table lamps, as it allows discreet cable routing and reinforces the internal structure of the assembly. It can also be used as a visible section in handcrafted lamps or minimalist designs where the metal's aesthetic takes centre stage.

Quick and secure installation

Installation is carried out using a threaded rod that passes through the interior of the tube. To ensure stable fixation, the rod must always be longer than the tube, allowing it to be secured with appropriate nuts or metal joints. The use of threaded fittings is especially recommended to prevent unwanted movements, ensure precise alignment, and facilitate assembly even for those without professional experience. The tube's design allows the wiring to be inserted without tension, protecting the insulation and enhancing installation safety.

Style and combination

Brass is highly valued for its warm and timeless aesthetic, making this tube naturally compatible with classic, contemporary, industrial, or vintage styles. It can be used in pieces where the metal is visible or integrated into hidden internal structures. Its metallic tone harmonises particularly well with wood, glass, marble, or textile lampshades in neutral tones. In more personalised projects, the tube can also be lacquered or patinated to match the final finish of the lighting fixture.

Maintenance and durability

Maintenance of the brass tube is minimal. To preserve its appearance, simply clean it with a soft, dry cloth or one slightly dampened. If you wish to restore shine or remove natural tarnishing of the brass, specific cleaners for this material can be used, applied gently. Its excellent resistance ensures stability even in lamps subjected to frequent movement or temperature changes typical of domestic use.

Final technical note

This tube must always be installed with compatible threaded rod and appropriate fastenings to ensure the stability of the assembly. Ensure that the wiring used meets the recommended gauge and complies with lighting safety standards. The product's features, photographs, or technical specifications may vary slightly depending on the manufacturer or production batch, without affecting its functionality, quality, or compliance with applicable safety standards.
