Pipe Makers | 20mm Medium Duty Rigid Conduit PVC | Grey
The RC20MD is a 20mm medium duty PVC conduit rated for above-ground cable protection in domestic and commercial installations. The RC20MD is supplied in 4-metre lengths and features a bell end on one side for easy coupling to fittings or additional conduit lengths. It complies with relevant Australian standards for electrical conduit systems.
Rigid PVC conduit protects cables on residential and commercial electrical installations. Electricians choose medium duty when budgets require durability without heavy duty orange cost. Use it for above-ground work where no water immersion or burial is a concern.
The RC20MD is a workhorse conduit for reno jobs and new-build wiring. Electricians carry it on every van because it's affordable, lightweight, and fast to cut and couple. It fixes securely to structures with metal saddles (for trades wanting permanence) or PVC saddles and cable ties (for speed on site). Standard stock on most jobs means faster quotes and smoother handoff to licensed installers.
Features
- 20mm diameter — fits standard 20mm electrical fittings, elbows, couplings, and junction boxes widely available at every electrical wholesaler.
- PVC construction — lightweight grey PVC resists cracking and impact on the jobsite, with no risk of rust or corrosion unlike metal conduit.
- 4-metre lengths — the RC20MD is supplied in standard 4m sections, reducing waste on most domestic circuit runs and minimising coupling requirements.
- Bell end design — one end has a slightly enlarged bell to simplify coupling to another piece of 20mm conduit or to plain-end fittings without needing male reducers.
- Above-ground rated — suitable for interior walls, surface wiring, and exposed cable runs where water immersion is not a concern; not for outdoor, damp, or underground applications.
- Easy to cut and work — PVC can be cut with a hacksaw or regular hand saw on site in seconds, with minimal cleanup of burrs using a file.
- Multiple fixing methods — works with metal saddles (half-round clips bolted to structures), PVC saddles (glued or nailed), or cable ties for flexible speed-of-fit applications.
- Affordable pricing — medium duty positioning keeps unit costs lower than heavy duty orange conduit while providing adequate mechanical protection on typical domestic and commercial installations.
- Standard stock item — the RC20MD is a high-turnover item stocked by nearly all Australian electrical wholesalers, supporting fast reorder and last-minute stock-up on site.
- Not suitable for outdoor or submerged installations — the RC20MD is an above-ground interior product and must not be used in wet areas, external walls, or locations subject to water immersion or UV exposure.
Where to use
- Domestic lighting circuits — the RC20MD protects cables running across ceiling voids, along wall surfaces, and through roof spaces on residential lighting and power subcircuits.
- Renovation and extension wiring — surface conduit on new walls, around door frames, and across additions is a standard specification for licensed electricians upgrading existing homes.
- New-build rough-in installations — the RC20MD is installed during framing before plastering and finishing, carrying cable from switchboards to light and power outlets throughout the building.
- Sub-board and circuit distribution — where cable routes from a main board to a sub-distribution point, medium duty conduit is faster and more cost-effective than burying cable in conduit underground or in slab.
- Commercial interior cable runs — offices, retail, hospitality, and small industrial sites use the RC20MD for branch circuits and secondary distribution within the building interior.
- Workshop and garage installations — surface-mounted conduit protects cables on workshop walls, across beams, and along pegboards where tools and equipment could otherwise damage exposed cable.
The RC20MD is not suitable for external walls, damp exposed locations, or underground applications. Do not use the RC20MD in bathrooms, laundries, kitchens with splash zones, or any wet environment. Outdoor installations and UV-exposed areas require orange heavy duty conduit or UV-resistant alternatives.
