Conduit Accessories
City Plumbing offers a wide selection of high-quality conduit accessories. Whether you’re routing complex wiring through a commercial site or tidying up a residential renovation, the right conduit accessories are what turn a bundle of pipes into a safe, professional management system.
What Are the Most Common Types of Conduit Accessories?
1. Bends & Elbows
When you need to alter the direction of a conduit run, bends and elbows are indispensable. While many professionals operate a bending machine for small offsets, prefabricated bends deliver uniform radii and avert internal cable kinks.
- Normal Bends: Smooth, 90-degree curves for standard corners.
- Inspection Elbows: Feature a removable plate that allows you to pull cables through or inspect for snags at a corner.
2. Conduit Boxes
Often called junction boxes, these serve as hubs in your installation, providing a safe area for wire connections and termination points.
- Configurations: Available in 1-way (terminal, at the end of a run), 2-way (through, allowing cables to pass straight through), 3-way (tee, branching in a T-shape), and 4-way (intersection, connecting four conduits).
- Mounting: Provide a robust platform for light fixtures or switches.
3. Clips & Saddles
To meet safety standards, conduit must be securely anchored to walls or ceilings to prevent sagging or accidental movement.
- Distance Saddles: Keep the conduit slightly away from the wall to prevent moisture build-up (accumulated water that may cause damage).
- Bar Saddles: Heavy-duty clamps suitable for high-traffic or industrial environments.
4. Couplers & Reducers
These components extend your conduit run or serve as transitions between pipe sizes.
- Couplers: Simple sleeves used to join two straight lengths of conduit together.
- Reducers: Allow you to connect a larger-diameter pipe (for example, 25mm) to a smaller one (for example, 20mm) when the pipe sizes differ.
5. Glands & Connectors
These parts, known as conduit fittings, are essential for terminating conduit at a distribution board or metal enclosure.
- Glands: Provide a secure, often watertight seal where the cable exits the conduit (the protective pipe for electrical wiring).
- Locknuts & Bushes: Secure conduit to box entry holes and prevent sharp edges from damaging insulation.
6. Adaptors
Adaptors bridge different systems, such as connecting rigid steel conduit to flexible PVC conduit. They're particularly valuable when linking machinery that vibrates or requires movement.
Conduit Accessories Typical Material Types
Choosing the right material for your conduit accessories is a balancing act between environmental considerations, safety regulations, and budget. The material determines how well the system will withstand physical impact, corrosion, and even fire.
1. PVC (Polyvinyl Chloride)
PVC is the go-to for domestic and light commercial applications. It is prized for its lightweight, incredibly easy-to-work-with properties.
- Benefits: Completely corrosion-resistant, non-conductive (which adds an extra layer of electrical safety), and cost-effective. It can be easily cut and joined using solvent cement.
- Typical Applications: Residential wiring, underground runs (due to moisture resistance), and environments where chemical vapours might corrode metal.
- Limitations: Becomes brittle in extreme cold and can sag in very high temperatures.
2. Galvanised Steel
In medium- to heavy-duty environments, galvanised steel is the industry standard. The "galvanised" coating (a layer of zinc) protects the steel from rusting.
- Benefits: High mechanical strength and excellent protection against physical impact. It also acts as an effective EMI (Electromagnetic Interference) shield for sensitive data cables.
- Typical Applications: Commercial warehouses, workshops, and parking garages where the conduit may be exposed to knocks from machinery or vehicles.
3. Malleable Cast Iron
When the highest level of durability is required, cast iron accessories are used. These are often paired with heavy-gauge steel conduit.
- Benefits: Exceptional "crush" resistance and superior fire protection. Unlike plastic, iron will not melt or emit toxic fumes in a fire, helping to maintain circuit integrity for emergency systems.
- Typical Applications: Industrial plants, heavy manufacturing, and high-occupancy public buildings where strict fire safety codes (like BS 7671) are a priority.
Compliance Standards For Conduit Accessories
When you source conduit accessories from City Plumbing, you get more than hardware; you invest in peace of mind. Every component is chosen to help trade professionals meet strict UK safety standards and regulations.
These compliance standards ensure our products are reliable, durable, and safe for any installation.
1. BS EN 61386: The Gold Standard for Conduit Systems
This primary British and European standard for conduit systems dictates how accessories are designed, tested, and classified. This means products have passed strict tests for:
- Temperature Range: Guarantees your installation’s performance in extreme heat and cold, preventing cracking or melting and reducing downtime.
- Electrical Properties: Helps you maintain electrical continuity in metallic systems and effective insulation in non-metallic systems, minimising the risk of faults and hazards.
Key Sub-parts to Look For:
- BS EN 61386-21: Ensures rigid conduit systems (steel and heavy-duty PVC) deliver maximum protection for fixed wiring, contributing to long-term reliability.
- BS EN 61386-23: Certifies that flexible conduit and associated connectors allow safe wiring adaptability, protecting installations where movement or vibration is present.
- BS EN 61386-24: Provides assurance that conduit systems intended for burial underground are designed to resist soil pressure and moisture, protecting your installations from deterioration.
2. BS 7671: The IET Wiring Regulations (18th Edition)
BS EN 61386 sets the product standard, while BS 7671 governs installation. Our accessories help you stay compliant with the latest amendments, especially regarding:
- Fire Safety (Regulation 521.10.202): This regulation requires wiring systems to be supported against "premature collapse" in the event of a fire. Our metal saddles and clips directly address this by keeping cables securely fixed to the building structure, even if plastic trunking fails. This ensures escape routes remain clear for emergency services.
- External Influences: Our accessories provide the IP ratings required by BS 7671 for damp, dusty, or outdoor installations.
3. IP Ratings (Ingress Protection)
For bathrooms, kitchens, or outdoor sites, our accessories comply with BS EN 60529.
- IP44: Keeps solid objects >1mm and splashing water out, making your installations safer in frequently used spaces.
- IP66/67: Dust-tight and protected against strong water jets or temporary immersion (ideal for heavy industrial wash-down areas).
