PVC Pipe Fittings 16–110mm — Versatile Connections for Aquarium, Pool & Plumbing

When a leaking joint or a missing fitting brings your aquarium build or pool circulation project to a standstill, having the right connector on hand makes all the difference. These PVC pipe fittings are designed for hobbyists, pond keepers, and DIY plumbers who need reliable, solvent-weld or threaded connections without sourcing from a trade counter.

The range covers straight couplings, 90° elbows, T-pieces, reducing sockets, adapter sockets, double nipples, solvent-socket elbows and T-pieces, brass-threaded variants, end caps, corrugated flexible hose, and 304 stainless hose clamps — all in PVC with sizes spanning 16 mm to 110 mm (approximately ½" to 4"). Colour options include white, grey, blue, dark grey, and black depending on fitting type.

Typical applications include aquarium sump return lines, koi pond filter circuits, irrigation manifolds, swimming pool pump plumbing, and general cold-water domestic pipework. The threaded brass-insert variants suit transition points where PVC meets metal valves or pumps, while the corrugated hose sections handle tight-radius routing where rigid pipe cannot bend.

⚙️ Compatibility: Designed for standard metric PVC pressure pipe (PN10/PN16 schedule). Solvent-weld sockets accept pipe OD matching the stated mm size. Threaded ends conform to BSP (British Standard Pipe) parallel thread. Verify your pipe OD and thread standard before ordering.

✅ Key Features of These PVC Pipe Fittings

  • 🔗17 fitting types in one listing — straight couplings, 90° elbows, T-pieces, reducing sockets, adapter sockets, double nipples, end caps, corrugated hose, and hose clamps, covering virtually every connection scenario in a single order.
  • 📏Wide size range: 16–110 mm (½"–4") — from compact aquarium return lines up to large-bore pool or irrigation mains, with metric OD and BSP thread sizes clearly stated per variant.
  • 🎨Multiple colour options — white, grey, blue, dark grey, and black allow colour-coded circuit identification or aesthetic matching in visible installations such as display aquariums.
  • 🔩Brass-threaded insert variants available — the 90° elbow (Messinggewinde), straight (Messinggewinde), and T-piece (Messinggewinde) types incorporate brass BSP threads for durable metal-to-PVC transitions at pump ports and valve bodies.
  • 🌊Corrugated flexible hose sections — available in 20 mm, 25 mm, 32 mm, and 40 mm diameters in lengths from 0.3 m to 1 m, providing vibration isolation and flexible routing between rigid pipe runs.
  • 🔒304 stainless steel hose clamps included — sold in pairs for 20 mm, 25 mm, 32 mm, and 40 mm corrugated hose, providing corrosion-resistant mechanical retention without additional hardware sourcing.

❓ Frequently Asked Questions

How do I choose the correct fitting size?

Match the fitting size to the outer diameter (OD) of your pipe, not the inner diameter. For example, a "20 mm" socket accepts pipe with a 20 mm OD. For threaded variants, match the BSP thread size (e.g., ½", ¾", 1") to the thread on your pump port or valve. If you are unsure, measure your existing pipe OD with calipers before ordering.

Are these fittings suitable for aquarium and pond use?

Yes. PVC is chemically inert and non-toxic once fully cured, making it widely used in aquarium sump plumbing, koi pond filter circuits, and reef tank return lines. Ensure solvent cement is fully cured (typically 24 hours at room temperature) before introducing water to the system. The white and blue colour options are particularly popular for visible aquarium builds.

What is the difference between solvent-weld sockets and threaded fittings?

Solvent-weld (klebemuffe / Muffe) sockets create a permanent chemical bond with PVC pipe using solvent cement — the joint becomes as strong as the pipe itself and is not intended to be disassembled. Threaded fittings (IG = Innengewinde / female thread; AG = Außengewinde / male thread) can be assembled and disassembled with PTFE tape and are used where future servicing is needed, such as at pump connections or filter inlets.

Can I use these fittings with CPVC or ABS pipe?

These fittings are designed for standard PVC pipe. CPVC pipe has a slightly different OD in some schedules and requires CPVC-rated solvent cement — compatibility is not guaranteed. ABS pipe uses a different solvent cement chemistry. For threaded connections, the BSP thread standard is compatible regardless of pipe material, provided the thread size matches.

What solvent cement should I use, and how long does it take to cure?

Use a PVC solvent cement rated for the pipe schedule and application (e.g., low-VOC aquarium-safe cement for fish-keeping use). Apply primer first on larger diameters (32 mm and above) for a stronger bond. Initial set typically takes 15–30 minutes; full cure for pressure testing is generally 24 hours at 20 °C. Follow the cement manufacturer's instructions for your specific ambient temperature and pipe size.

Are the brass-threaded fittings compatible with standard metal valves and pumps?

Yes. The brass-insert variants (Messinggewinde) use BSP parallel threads, which are the most common thread standard on European and UK pumps, valves, and filter heads. Wrap the male thread with 2–3 layers of PTFE tape before assembly to ensure a watertight seal. Do not overtighten — hand-tight plus approximately one full turn with a wrench is sufficient for BSP parallel threads.

How do I select the right corrugated hose length and diameter?

Choose the diameter to match your pipe OD (20 mm, 25 mm, 32 mm, or 40 mm). For length, measure the distance between the two rigid pipe ends with a small allowance for the natural curve of the hose — typically add 10–15% to the straight-line distance. The 304 stainless hose clamps (sold separately in this listing) are sized to match each hose diameter and provide a secure, corrosion-resistant connection.
