Pipe Clamp Size Guide
There can be a lot of confusion when ordering pipe clamps, this is generally caused by differing dimensions and product codes used by the different manufacturers.
To try and help there is a Pipe Clamp Equivalents Chart which lists many of the popular manufacturer codes
We show both our own product codes (Prod. Code) and the manufacturers codes (Stock Code) on our pages where available.
In many of our product titles, you will see a Prod. Code that looks like this: C00G20, simply put it can be broken down as
C00 = Fitting Type
G = Galvanised
P = Plastic
S = Stainless Steel
20 = The pipe size - nominal bore
Also within many page descriptions there is a code that looks like 125-1 this relates to the Q Clamp or Kee Klamp® size in the equivalence chart
125 = Fitting Type
1 = The pipeclamp size
The diagram below shows how these codes relate to the size and outside diameter of the pipe in mm:
Pipclamp Size | Pipe dia. (mm) O/D | Pipe dia. (in) O/D | Nominal Bore (mm) | Nominal Bore (in) |
1 | 26.9 | 1 1/16 | 20 | ¾ |
2 | 33.7 | 1 11/32 | 25 | 1 |
3 | 42.4 | 1 11/16 | 32 | 1 ¼ |
4 | 48.3 | 1 29/32 | 40 | 1 ½ |
5 | 60.3 | 2 3/8 | 50 | 2 |
