Grey PVC 32mm ID Pressure Pipe Fittings Metric Solvent Weld Various Parts

These fittings are sized for standard metric grey PVC pressure pipe with a 32mm outer diameter (OD). They are not compatible with imperial-sized pipe. If you are unsure, measure the outside diameter of your existing pipe — it should be 32mm (approximately 1.26 in) for a correct solvent-weld fit.

No. Grey PVC is rated for cold-water pressure service only. It is not suitable for hot water, central heating, or steam applications. For hot water systems, consider CPVC or polypropylene fittings rated for elevated temperatures.

These are solvent weld fittings. You apply PVC solvent cement to both the pipe end and the fitting socket, push them together with a slight twist, and hold for a few seconds. No heat gun or specialist tools are required. The pipe scissors variant (16–42mm) in this listing can be used to cut the pipe cleanly before cementing.

Yes. The brass FBSP (female BSP) and MBSP (male BSP) socket adaptors conform to standard BSP thread profiles, allowing connection to taps, pumps, filters, and other threaded plumbing components. PTFE thread seal tape (also available in this listing) should be used on all threaded connections to ensure a watertight seal.

For aquarium and sump applications, the dedicated Fish Tank Connector (Straight) and Fish Tank Connector (90° Elbow) variants are designed for bulkhead-style through-tank connections. The Fish Tank Drainage (Straight) and Fish Tank Drainage (90° Elbow) options suit overflow and drain lines. Pair with the 32mm Silicone Washers for a watertight bulkhead seal.

Both union types allow the pipe run to be disconnected without cutting, which is useful for servicing valves or equipment. The Old Type and New Type refer to different collar and seal designs. If you are replacing an existing union, match the type to your current fitting. If installing new, either type is suitable — the New Type typically features an updated sealing mechanism for improved reliability.

A reducing socket has a full socket on both ends and steps down the pipe size mid-run — both pipes insert into the fitting. A reducing bush is a short insert that fits inside a same-size socket to reduce the bore, allowing a smaller pipe to connect into a larger fitting. Use a reducing socket for inline reductions and a reducing bush when you need to adapt an existing socket fitting to accept a smaller pipe.
