Metric PVC Plain to Threaded Pipe Fittings FAQ

Below you'll find answers to the most common questions about our metric PVC plain to threaded pipe fittings collection. If you need further help, our technical team is always ready to assist.

What are metric PVC plain to threaded pipe fittings used for?

These fittings allow you to transition between a plain (solvent weld) connection on one end and a threaded (BSP) connection on the other. They are commonly used in water treatment, chemical processing, irrigation systems, and industrial pipework where you need to join metric PVC pipework to threaded valves, equipment, or existing threaded pipelines.

What sizes of metric PVC plain to threaded fittings do you stock?

Our collection covers a range of standard metric sizes to suit most industrial and commercial applications. For the full list of available sizes, browse the collection page or contact our team directly. We can also help source specific sizes if you don't see what you need listed.

Are these fittings compatible with BSP threads?

Yes, the threaded ends on our metric PVC plain to threaded fittings are manufactured to British Standard Pipe (BSP) thread specifications. This ensures reliable compatibility with BSP-threaded valves, couplings, and other pipeline components commonly used across UK installations.

What type of PVC are these fittings made from?

These fittings are manufactured from PVC-U (unplasticised PVC), which is the industry standard for pressure pipework systems. PVC-U offers excellent chemical resistance, durability, and long service life, making it suitable for a wide range of fluids and operating conditions.

Can I use solvent cement on the plain end of these fittings?

Absolutely. The plain (socket) end is designed for solvent welding to metric PVC pipe. Use a suitable PVC solvent cement and follow the manufacturer's preparation and curing guidelines to achieve a strong, leak-free joint. If you're unsure which adhesive to use, get in touch and we'll recommend the right product.

Should I use PTFE tape on the threaded end?

We recommend using PTFE thread seal tape on all threaded connections to ensure a watertight seal. Wrap the tape clockwise around the male thread before assembly. Avoid over-tightening, as excessive force on PVC threads can cause cracking or damage to the fitting.

What pressure ratings do these fittings support?

Pressure ratings depend on the specific fitting size and the operating temperature of your system. Generally, PVC-U fittings are rated for use in pressure systems at temperatures up to around 20°C, with derating applied at higher temperatures. For exact pressure specifications, please contact our technical team with your application details.
