When your plumbing or irrigation project demands a reliable step-down between two different pipe diameters, a poorly fitted reducer can cause leaks, pressure loss, and costly rework. These long tapered PVC reducer socket fittings are engineered for DIYers, plumbers, and irrigation installers who need a secure, leak-free transition between mismatched pipe sizes — without compromise.
Each fitting is manufactured from rigid PVC (polyvinyl chloride) and features a long conical socket design that accepts solvent cement bonding on both ends. The large-head socket accommodates the larger pipe OD, while the smaller-head socket receives the reduced pipe. Available in outer diameter combinations ranging from 25×20mm (approx. 1"×¾") up to 160×125mm (approx. 6¼"×5"), with color options in White, Blue, and Gray to suit different system coding conventions.
Ideal for residential cold-water supply lines, garden drip irrigation manifolds, pool and spa plumbing transitions, and industrial PVC pipe networks where a long-taper reducer socket fitting provides superior pull-out resistance compared to short-pattern alternatives.

Measure the outer diameter (OD) of both pipes you need to connect. The large-head socket OD should match your larger pipe, and the small-head socket OD should match your smaller pipe. For example, if you are stepping down from a 50mm pipe to a 32mm pipe, select the 50×32mm variant. If you are unsure, contact us with your pipe measurements and we can confirm the correct fit.
These fittings are designed for metric OD PVC pipe (DIN 8061/8062 standard). Many metric OD sizes are dimensionally close to Schedule 40 nominal sizes, but they are not always interchangeable. Always verify the actual outer diameter of your pipe against the fitting socket size before ordering. If you are working with imperial Schedule 40 pipe, please contact us to confirm compatibility.
Use a standard PVC solvent cement (also called PVC glue or PVC adhesive) rated for pressure pipe applications. For best results, apply a PVC primer/cleaner to both the pipe end and the socket interior before applying the cement. Follow the cement manufacturer's cure time instructions before pressurizing the joint — typically 15–30 minutes for initial handling strength and 24 hours for full cure.
The long conical socket design provides a larger bonding surface area compared to short-pattern reducer sockets, resulting in improved pull-out resistance and a more robust joint. When properly primed and cemented, a solvent-weld PVC joint typically exceeds the burst strength of the pipe itself. The long taper also helps center the pipe during assembly for a more consistent bond.
No. These fittings are manufactured from standard rigid PVC, which is rated for cold-water service (typically up to 60°C / 140°F). They are not suitable for hot water supply lines, CPVC systems, or applications exceeding the rated temperature. For hot water applications, please use CPVC fittings specifically rated for that purpose.
All three colors are made from the same rigid PVC material and offer identical mechanical performance. The color difference is primarily for system identification and coding: White is the most common general-purpose color; Blue is often used to indicate potable (drinking) water lines in some regional standards; Gray is commonly associated with drainage or industrial systems. Choose the color that matches your existing pipework or local coding convention.
No. Solvent cement creates a permanent chemical fusion between the pipe and fitting — the joint cannot be disassembled without cutting. If you need a removable connection, consider using a union fitting in combination with this reducer socket. Always dry-fit and verify alignment before applying cement.
Yes. When you select a specific size combination (e.g., 50×32mm) and a quantity of 5 or 10, all pieces in the pack will be identical — the same size and color as selected. Multi-packs are ideal for projects requiring multiple reduction points of the same diameter step.
