What’s the difference between PVC Pipe Fittings?

A PVC Fitting is the physical connector that joins more than one pipe together to create a pipe system.

PVC Pipe is widely seen on many pipe systems. In one pipe system, you are likely to see extremely similar pipe throughout it, however the fittings can vary massively depending on how the pipe needs to be navigated through or around buildings.

What PVC Pipe fittings do epco offer?

As you can imagine, there is a massive variation when it comes to PVC fittings as every pipe system has a different purpose, in a different location, with a different layout. Because of this, it’s very unlikely that 2 pipe systems are going to have exactly the same PVC fittings used within them.

As you can see below, epco offers a wide range of Fittings, covering all of your PVC pipe system requirements.

We have a number of other pipe fittings available and also offer a difference in plain, threaded and plain / threaded fittings in the majority of the pipe fittings listed above.

We offer PVC fittings in both Imperial and Metric sizes. You can see the full list below.

  2. Metric PVC Fittings

PVC Plain Fittings vs Threaded

Plain fittings are what you would describe as the most similar looking to a piece of pipe, however shaped into an actual fitting. A plain fitting is used to connect 2 pieces of pipe together.

Threaded fittings have multiple rings on the inside of the fittings, often resembling something that can be screwed into place. Threaded fittings are used to connect other threaded fittings together, often to create a change in the pipe direction.

Plain / Threaded fittings are used to connect a plain fitting / pvc pipe into a a threaded fitting, as well as a threaded fitting into a plain fitting.

One key advantage of using threaded PVC pipe fittings is that the entire pipe system can be easily dismantled and altered to be reassembled and changed as per your requirements. However, the assembly of the threaded system has to be done correctly with PTFE thread seal tape.

Technical Standards for our PVC Pipe and Fittings

All our products are manufactured in accordance with strict relevant international dimensional standards.

In simplistic terms, the dimensional standards dictate that the pipes must be produced within a tolerance band i.e. the outside diameter of the pipe has to fall between the “minimum” and “maximum” dimensions set by the relevant pipe system standard, being the outside diameters and tending to be the “average” of these two dimensions outlined in the standard.

Details of our pipe system standards are below:

Metric uPVC products are generally manufactured in accordance with the following standards:

  • Pipe - EN1452-2
  • Fittings - EN1452-3, ISO161/1
  • Threaded Fittings - BS21, DIN2999, ISO7
  • Pressure ratings for solvent weld Metric fittings are usually 16 bar up to 160mm o.d. 
  • Threaded fittings are rated at 12 bar.
  • * All quoted at 20ºC

Imperial uPVC products are generally manufactured in accordance with the following standards:

  • Pipe - EN1452-2
  • Fittings - EN1452-3 / BS4346 Part 1
  • Threaded Fittings - BS21, DIN2999, ISO7
  • Unless otherwise stated uPVC Pressure Fittings have the following pressure ratings:
  • Solvent Weld - 3/8” to 8” = Class E/15 bar
  • Threaded = Class D/12 bar
  • * All quoted at 20ºC
