When a leaking joint derails your plumbing or irrigation project, the fitting is almost always to blame. DIY builders, plumbers, and garden system installers need a socket coupling that bonds cleanly, holds pressure, and fits standard pipe without guesswork. These PVC solvent-weld socket couplings deliver exactly that — a straight, female-to-female connector designed for permanent, leak-free pipe joints.
Each coupling is made from rigid PVC plastic and features a smooth internal bore sized to accept standard pipe OD. Available in six sizes — 20mm (~¾"), 25mm (~1"), 32mm (~1¼"), 40mm (~1½"), 50mm (~2"), and 63mm (~2½") — and sold in packs of 1, 2, 3, or 5 pieces to match your project scope. Wall thickness is proportional to pipe diameter and conforms to typical DIN/ISO PVC pipe standards.
Typical applications include cold-water supply line repairs, garden drip irrigation manifolds, pool and spa plumbing connections, and workshop compressed-air PVC pipe runs. Long-tail use cases: PVC socket coupling for irrigation pipe repair, straight pipe connector for 32mm PVC plumbing, solvent-weld muffe fitting 50mm cold water supply.
Designed for PVC solvent cement application. The glue-type socket creates a chemically fused, permanent joint that resists vibration and pressure surges.
Available in 20mm, 25mm, 32mm, 40mm, 50mm, and 63mm inner socket diameters — covering the most common residential and light-commercial PVC pipe sizes.
The internal (Innen/Muffe) socket geometry ensures full pipe insertion depth and even cement distribution for a watertight seal on cold-water systems.
Manufactured from rigid, impact-resistant PVC. Maintains dimensional stability across typical cold-water operating temperatures (up to approximately 60°C / 140°F).
Order 1, 2, 3, or 5 pieces per size. Stock exactly what your repair or installation requires without over-ordering.
A simple, inline coupling with no reduction — ideal for extending pipe runs, splicing cut sections, or replacing a damaged segment of the same diameter.

These couplings are available in six inner socket diameters: 20mm, 25mm, 32mm, 40mm, 50mm, and 63mm. Select the size that matches the outer diameter (OD) of your existing PVC pipe. Standard PVC pressure pipe OD matches the nominal size listed (e.g., a 25mm coupling fits 25mm OD pipe).
No. These are designed specifically for rigid PVC-U (uPVC) pipe using solvent cement. They are not compatible with CPVC, ABS, or push-fit / compression-fit systems. Using the wrong cement or pipe type may result in joint failure.
Use a PVC-U solvent cement rated for pressure pipe applications. Apply primer first if required by your local plumbing code. Follow the cement manufacturer's cure time before pressurizing the system — typically 15–30 minutes for initial set and 24 hours for full cure.
No. Rigid PVC-U is rated for cold-water service only, typically up to approximately 60°C (140°F) at reduced pressure. For hot water, steam, or high-temperature applications, use CPVC or copper fittings instead.
A properly made solvent-weld joint is as strong as the pipe itself and can handle the full rated working pressure of the pipe system. PVC-U pressure pipe is commonly rated at 10–16 bar (145–232 psi) depending on wall thickness and temperature. Ensure full insertion depth and even cement coverage for a reliable bond.
Choose the quantity that matches your project needs. A single coupling suits a one-off pipe repair. Packs of 2–3 are useful for small irrigation manifolds or multi-joint repairs. A 5-piece pack offers the best per-unit value for larger installations or when keeping spares on hand for future maintenance.
Yes. These PVC socket couplings are well suited for garden drip irrigation and sprinkler pipe runs where standard PVC pressure pipe is used. Ensure the pipe OD matches your selected coupling size, and use a PVC-rated solvent cement for a watertight, long-lasting connection.
