Connectors and Pipes 



What does the abbreviation "PN" stand for on PVC pipe?
It stands for "Pressure Nominal" (The higher number have thicker walls on PVC pipe)

What does the abbreviation "PVC" stand for?
It stands for "Polyvinyl Chloride"

What does the abbreviation "DN" stand for?
It stands for "Diameter Nominal"

What does the abbreviation "DWV" on PVC pipe stand for?
It stands for "Drain, Waste, Vent" (This pipe is not compatible with Klever Cages PVC connectors).


What PVC pipe do I buy for connectors I purchased from Klever Cages? 

The pipe is required to be AS 1477 Series 1, plumbing PVC pressure pipe.

I have listed the outside diameter of the PVC pipe to fit our connectors below :

20mm PVC pipe outside diameter = 26.67mm

25mm PVC pipe outside diameter = 33.40mm

32mm PVC pipe outside diameter = 42.10mm

40mm PVC pipe outside diameter = 48.26mm

50mm PVC pipe outside diameter = 60.32mm

Can I use electrical conduit with Klever Cages PVC connectors?

Unfortunately not, as the outside diameter is different from PVC plumbing pipe.


Can I use DWV PVC pipe with Klever Cages PVC connectors?

Unfortunately not as DWV pipe is drain, waste and vent pipe and Klever Cages PVC connectors only fit standard PVC plumbing pressure pipe.


Where can I buy the PVC pipe to fit Klever Cages connectors?

Klever Cages selsl 1m lengths 20mm and 25mm clean PVC pipe on our website (no writing or markings)   

PVC pressure pipe (plumbing) is also available from major hardware and plumbing stores.


Why does my pipe not fit the PVC connectors I have purchased from Klever Cages?

There can be confusion about the sizing of the pipe used to build with the PVC connectors.

Hopefully, I can assist with clearing this up below:


The size (DN number) written on PVC plumbing pressure pipe is the "nominal bore size diameter", not the inside or the  outside diameter. 

PVC pipe marked DN20 (20mm PVC plumbing pressure pipe) PN12 - (Wall thickness 

    • Outside diameter 26.67mm
    • Inside diameter 23.7mm
    • Wall thickness 1.5mm 

As you can see in the above example none of these measurements are 20mm. The 20mm is a nominal size given to the pipe.

Can I send your PVC connectors back because they are the wrong size.

If you want to send the connector back because you believe we have sent you the wrong size please contact us first.

As per the information above it may actually not be the incorrect size and just the wrong pipe has been used. 

When we receive any connectors that have been sent back as long as they are in good condition we will refund the product amount only. 

Please make sure the order number is in the bag so we can identify the order we need to refund.


Can I use PVC connectors to repair my tent, greenhouse or a kids tent?

To all of the above questions if you have not made the structure yourself from PVC connectors and PVC plumbing pressure pipe the answer will be a "no". The reason for this is most of the structures mentioned above come in a kit and use their own size pipes. Our pipes are more general and use PVC plumbing pressure pipe which has a different outside diameter to that of your kit.



What is the maximum span for my PVC pipe when constructing my project?

We recommend the below lengths for the different size pipes.


  • 20mm pipe no more than 1m
  • 25mm pipe no more than 1.5m


Then from there, it is about half a meter each size up.  It also depends on what you are using the structure for, but without load, the above is correct.

If you would like to go longer than this, you can use tee pieces or L-tees to give the structure some reinforcement.


Will my project last in the Australian sun.

Both the connectors and the pipes that we sell are UV stabilised. We have the pipes made custom for us, and they contain  (Titanium Dioxide)  about 1.5 PPHR so they will last outdoors in our conditions. 


Do your PVC pipes contain lead? 

There is no lead in the stabiliser.

We use Calcium Zinc stabiliser (CaZn). 


What do I do if I require a part that I cannot see on your website?

If you cannot see a part that you require to finish your project, please send us an email, and we can see what we can do.
