Frequently asked questions about the Installation pipes and accessories category
What are Installation pipes and accessories and what are they used for?
Installation pipes and accessories are electrical products used to protect wires and cables and to simplify installation and maintenance. The category includes flexible plastic conduit (eg. 16–25 mm), aluminium LED profiles, connecting couplings, 90° corner fittings and pipe clamps for routing and securing electrical wiring.
What types of installation pipes are available (diameters and materials)?
The range includes flexible plastic conduit in 16 mm, 20 mm and 25 mm diameters (15 m coils), plus aluminium LED profiles with PC covers. Materials are PVC/plastic for flexible conduits and aluminium with PC diffuser for LED profiles.
How do aluminium LED profiles SP01, SP03 and VT-8113 differ?
SP01 and SP03 differ by mounting style: SP01 suits recessed or surface mounting with various covers, while SP03 includes clips for quick installation. VT-8113 is a 2 m aluminium profile; choose it based on LED strip width and required installation depth (eg. 16x6 or 22x6 mm).
What fittings are needed to join plastic installation pipes?
Use connecting couplings and 90° corner couplings sized to the pipe diameter, e.g. AJ40 coupling for 40 mm pipes or JMKL 32/40 mm corner couplings for bends. Always match the coupling to the conduit’s internal diameter.
What fixings are used to secure pipes to walls or ceilings?
Use pipe clamps and mounting brackets, for example DN100 pipe clamp with two bolts for large conduits. LED profiles use dedicated mounting clips and end caps (SP01/SP03) for neat installation and finishing.
Can these installation pipes be used for concealed wiring in a wall?
Yes — the flexible plastic conduits can be used for concealed wiring if installation regulations are followed and the correct diameter (16–25 mm) is chosen for the number of cables. Also use appropriate couplings and seals to maintain integrity.
Which profile should I choose for a 10 mm LED strip — 16x6 or 22x6?
Use the 16x6 mm profile for narrow LED strips around 10 mm. Choose the 22x6 mm profile if the strip is wider or you need improved heat dissipation and light diffusion; also consider a PC cover for even light distribution.
What accessories are available to finish a profile — end caps and corners?
Available accessories include end caps (OTSAKATE SP01 etc.) and 90° corner pieces (NURK 90° SP01) for corner joints and end finishing. They provide a neat appearance and protect LED strips from dust.
Which connectors are suitable for outdoor and watertight wire connections?
Use openable IP68-rated junction couplings and quick-seal connectors (eg. JÄTKUMUHV) for outdoor watertight joins. They suit conductors 0.5–2.5 mm² and provide moisture protection for external installations.
How to choose conduit diameter based on number of cables?
Choose diameter with margin: 16 mm suits one–two thin conductors, 20–25 mm for multiple or power cables. Leave about 30–40% free cross-sectional area for easier pulling and ventilation.
Which items from the category are most used for lighting and LED strip installation?
Common items are aluminium LED profiles (SP01, SP03, VT-8113), PC covers, end caps and mounting clips. Flexible plastic conduits 16–20 mm are also often used to route cables to fixtures.
