Metric PVC Plain to Threaded Pipe Fittings

Metric PVC Plain to Threaded Pipe Fittings — Flexible, Reliable, and Easy to Install

Metric PVC plain to threaded pipe fittings give you a secure, adaptable way to connect plain-end metric PVC pipe to threaded accessories such as pumps, valves, filters, and tanks. We make them from high-quality uPVC, giving you a lightweight, corrosion-resistant fitting that suits domestic, commercial, agricultural, and industrial systems. Furthermore, the combination of a solvent-weld plain end and a BSP threaded end means you can create both permanent and removable joints in the same run. Consequently, these fittings suit any project where you need fixed pipework alongside parts that come off for servicing. For plain-end solvent-weld fittings, see our Metric PVC Plain Pipe Fittings. Flanged connections are available in our Metric PVC Flanges & Gaskets range. For guidance on PVC fitting standards and pressure ratings, refer to the BSI Group, which publishes relevant British standards for plastic piping systems.

In short, metric PVC plain to threaded pipe fittings suit water supply, irrigation, aquaculture, swimming pools, chemical handling, and any system where you need both fixed and removable connections.

Key Features and Benefits

These fittings offer several clear advantages over all-solvent-weld and metal alternatives. The dual-jointing design is what sets metric PVC plain to threaded pipe fittings apart from standard solvent-weld fittings. For example:

• Dual jointing — Plain solvent-weld ends create permanent, watertight bonds. Threaded ends use PTFE tape for leak-free joints you can undo for servicing. Consequently, one fitting type covers both fixed and removable connections in the same system.
• Corrosion and chemical resistance — uPVC resists rust, scaling, and a wide range of chemicals. Therefore, these fittings give a long service life in aggressive fluid environments where metal would corrode quickly.
• Lightweight and easy to handle — Much lighter than metal fittings, so you can work quickly without heavy tools. Moreover, this keeps installation costs and project time down on site.
• No specialist tools needed — Apply solvent cement to the plain end and PTFE tape to the thread. As a result, both professional installers and confident DIY users can complete a joint quickly and reliably.
• Metric sizing — Sized in millimetres for direct compatibility with metric PVC pipe and fittings. Furthermore, this ensures accurate fits and leak-free connections throughout the system.
• Wide range of types — Available as adaptors, couplings, elbows, tees, and reducers. Overall, this gives you the flexibility to build complex layouts and connect to threaded accessories at any point in the run.
• Cost-effective — More affordable than metal equivalents and with a long service life. In addition, reusable threaded joints mean you rarely need to replace the fitting itself, only the PTFE tape.

Applications

These fittings suit a broad range of sectors where flexible, serviceable pipe connections are needed. The following examples show where metric PVC plain to threaded pipe fittings deliver the most value:

• Domestic plumbing — Link metric PVC pipe runs to water tanks, filters, and appliances where future access for maintenance or upgrades is important. Threaded joints let you swap out components without cutting the pipe.
• Agriculture and irrigation — Build irrigation networks and livestock watering systems where pumps and filters need regular removal for servicing. Furthermore, uPVC resists fertilisers and treated water without degrading.
• Aquaculture and fish farming — Connect water circulation and filtration pipework in fish tanks and hatcheries. Chemical and saltwater resistance keeps the fittings reliable over a long service life.
• Swimming pools and leisure facilities — Join circulation pumps, heaters, and filters where regular equipment servicing is needed. In addition, chemical resistance suits chlorinated and treated pool water systems.
• Industrial chemical handling — Transport acids, alkalis, and process fluids safely. Strong chemical resistance and removable joints suit industrial settings where pipework needs regular inspection and part replacement.
• Commercial water systems — Water distribution in offices, hotels, and schools where reliable, serviceable connections keep downtime short. Moreover, metric sizing ensures compatibility with modern millimetre-based pipework throughout the building.

Installation and Long-Term Value

Installing these fittings is simple. For the plain end, clean and degrease the pipe and socket, then apply uPVC solvent cement for a permanent, watertight bond. Allow the joint to cure fully before pressurising the system. For the threaded end, wrap the thread with two to three layers of PTFE tape and hand-tighten before giving a quarter turn with a spanner. Furthermore, avoid over-tightening, which can crack the fitting body. Always check the pressure rating of each fitting against your system’s working pressure before connecting.

Maintenance is minimal. The solvent-weld end needs no attention once set. In addition, threaded joints come apart quickly for inspection or part swap without cutting the pipe. Overall, uPVC does not rust, scale, or corrode, so the fittings stay in good condition for many years with very little upkeep.

From a cost point of view, uPVC fittings cost less than metal equivalents, go in faster, and last far longer. In short, our metric PVC plain to threaded pipe fittings give you a strong, flexible, and cost-effective connection solution for almost any domestic, agricultural, commercial, or industrial piping system.
