PVC Reducer Sockets — Metric Plumbing Fittings for Reliable Pipe Diameter Transitions

When a drainage or waste-pipe run changes diameter mid-system, a poorly matched reducer can cause leaks, blockages, or stress cracks that are expensive to fix inside a finished wall. These PVC reducer sockets are designed for DIYers and trade plumbers who need a dependable, solvent-weld transition fitting that seats flush and holds under continuous flow.

Each fitting is moulded from rigid uPVC and is available in two configurations — Concentric Reducer Sockets (where both pipe axes share the same centreline) and Eccentric Reducer Sockets (where one side of the socket sits flat, keeping the pipe invert level). Sizes span 75 mm × 50 mm (~3" × 2") up to 400 mm × 315 mm (~16" × 12"), covering the most common metric pipe diameters used in residential and light-commercial plumbing.

Typical applications include connecting 110 mm soil pipes to 75 mm branch lines in bathroom drainage, stepping down 160 mm underground drainage to 110 mm internal stacks, and reducing 315 mm or 400 mm large-bore stormwater mains to smaller distribution pipes in commercial fit-outs or civil drainage projects.

🔗 Compatibility: Designed for metric uPVC pressure and drainage pipe conforming to common DIN/EN standards. Verify your pipe's outer diameter before ordering. Not intended for CPVC, ABS, or imperial-sized pipe without an adapter.

✅ Key Features of These PVC Metric Reducer Sockets

  • 🔩 Two socket styles in one listing — choose Concentric (aligned centreline) or Eccentric (flat invert) to match your pipe layout and gravity-flow requirements.
  • 📏 Wide metric size range — 17 size combinations from 75×50 mm up to 400×315 mm, covering the majority of residential and commercial metric drainage diameters.
  • 🛡️ Rigid uPVC construction — resists corrosion, scale build-up, and common household chemicals; rated for continuous use in drain, waste, and vent (DWV) applications.
  • 🔧 Solvent-weld socket ends — standard push-fit spigot depth allows a full solvent-cement bond for a leak-free joint that meets typical DWV installation requirements.
  • ⚖️ Lightweight yet structurally rigid — easy to handle and position in confined ceiling or wall cavities without sacrificing the wall thickness needed for long-term joint integrity.
  • 🏗️ Suitable for buried and above-ground runs — the uPVC formulation handles typical soil loads when bedded correctly, making these fittings usable for both internal stacks and shallow underground drainage.

❓ Frequently Asked Questions

How do I choose between a Concentric and an Eccentric Reducer Socket?

A Concentric Reducer Socket keeps both pipe centrelines aligned — ideal for vertical stacks or runs where the pipe can drop symmetrically. An Eccentric Reducer Socket keeps one side of the pipe flat (the invert), which is essential for horizontal runs where you need to maintain a consistent fall and avoid air pockets that cause gurgling or slow drainage.

Which size reducer do I need for my pipe?

Match the socket sizes to the outer diameter (OD) of your existing pipes — for example, a 110×75 mm reducer connects a 110 mm OD pipe to a 75 mm OD pipe. Measure your pipe's outside diameter with calipers or a tape measure before ordering. If you are unsure, contact us to confirm compatibility.

Are these fittings compatible with imperial-sized PVC pipe?

These reducer sockets are sized to metric uPVC pipe dimensions (DIN/EN standards). Imperial pipe ODs differ from metric ODs even at nominally similar sizes — for example, a 4" imperial pipe has a different OD than a 110 mm metric pipe. If you are working with imperial pipe, a dedicated metric-to-imperial adapter fitting is required.

Can these reducers be used underground or in buried drainage?

Yes. Rigid uPVC is suitable for shallow underground drainage when the trench is properly bedded with granular material and backfilled to manufacturer guidelines. For deeper or high-load applications (e.g., under driveways), verify that the wall thickness of the selected variant meets the relevant local standard for buried pipe.

What solvent cement should I use to bond these fittings?

Use a uPVC-rated solvent cement (also called solvent weld adhesive) that complies with your local plumbing code — typically a one-step or two-step (primer + cement) system. Clean and dry both the pipe spigot and socket bore before applying cement, and allow the full cure time specified by the cement manufacturer before pressure-testing the joint.

How do I confirm the fitting will resist the chemicals in my drainage system?

Rigid uPVC has good resistance to dilute acids, alkalis, and common household drain cleaners at normal drainage temperatures (typically up to around 60 °C intermittently). For industrial effluent or continuous high-temperature discharge, review a uPVC chemical resistance chart against your specific fluid and temperature before installing.

Can I use these fittings for pressure (supply) pipework as well as drainage?

These fittings are listed for drain, waste, and vent (DWV) use. If you intend to use them in a pressurised water supply system, confirm that the pressure rating and wall thickness of the specific variant you select meets the working pressure of your system. Contact us to confirm suitability for pressure applications.
