Pipe Makers | 25mm Medium Duty Rigid Conduit PVC | 4 Metre
The Pipe Makers RC25MD is a 25mm medium duty rigid PVC conduit supplied in 4 metre lengths. Medium duty conduit is used to install and protect electrical cables above ground without requiring a full enclosure system. The RC25MD is commonly used on domestic, commercial, and industrial installations where cabling needs mechanical protection during installation and throughout its operating life.
Electricians use medium duty conduit on walls, under floors, and in cavities where cable needs protection but a full enclosure is not required. Cost matters on every job, so medium duty offers solid value: it is lighter and faster to fit than heavy duty, yet stronger than flexible conduit. The grey PVC is UV-stable outdoors and resists salt air and moisture better than cheaper vinyl.
The RC25MD delivers a reliable product across every installation type. It fits standard 25mm fittings and couplings without adaptors, and the bell end design slips over the next section or directly into fittings — no threading, no crimping, no surprises. Electricians secure it with metal saddles on steel, PVC saddles on plasterboard, or cable ties depending on the surface. Stock rotation is straightforward since the RC25MD is one of the most commonly ordered conduit sizes across Australian jobs.
Features
- 25mm diameter — fits all standard 25mm conduit fittings, couplings, and elbows without modification.
- Bell end design — one end is slightly flared to accept the plain end of the next section or to slip into 25mm fittings; no threading or crimping required.
- UV-stable grey PVC — withstands outdoor exposure without yellowing, brittling, or cracking; resists corrosion from moisture and salt air better than cheaper vinyl compounds.
- Medium duty rating — stronger than light duty (flexible) conduit but lighter and easier to cut than heavy duty; ideal for above-ground runs on most domestic and commercial jobs.
- 4 metre length — reduces on-site joins and fittings cost; one 4m length covers a typical residential room run from switchboard to outlet.
- Smooth bore surface — allows cable to feed through with minimal friction, cutting installation time compared to conduit with internal ridges or burrs.
- Fixable with multiple methods — metal saddles, PVC saddles, or cable ties all work depending on surface type; plastic saddles grip the round surface without crushing.
- No electrical rating required — the conduit itself carries no voltage rating; it is purely mechanical protection, so compatibility is universal across earthed or unearthed installations.
- Not weatherproof as a standalone — conduit protects cable from physical damage but not from water ingress if submerged or under constant spray; use heavy duty or schedule fittings and glands for wet areas.
- Above ground installation only — medium duty PVC is designed for aboveground runs; for underground applications, use rigid HDPE or steel conduit rated for burial.
Where to use
- Domestic new builds and renovations — the RC25MD is specified in new houses and renovations to route cable from the switchboard to walls, along ceiling cavities, and within wall frames before plasterboard goes up.
- Commercial office and retail installs — medium duty conduit runs cable above suspended ceilings or under raised computer floors where space is tight and light duty flexible conduit would snag.
- Industrial machine wiring — electricians use the RC25MD to route power and control cable to machinery where the cable is exposed but not in an enclosure; the bell end fits standard industrial fittings.
- Surface-mounted runs on walls and ceilings — one of the most common applications; the smooth grey finish suits both workshop and residential environments.
- Subfloor and cavity runs — the RC25MD feeds through building cavities between joists or along concrete floors under later flooring, protecting cable from nails, screws, and abrasion.
- Garden shed and outdoor installations — the UV-stable grey PVC resists fading and brittleness in outdoor sheds and temporary buildings; still requires protection from direct water spray or burial.
The RC25MD is not suitable for underground burial, water-immersed, or constantly wet locations. Do not use medium duty conduit in applications requiring IP66 water-tight enclosures or where the conduit will be submerged. For wet areas, use heavy duty conduit, sealed glands, and weatherproof junction boxes.
