Download the BFM® IG Calculator

 

The BFM® Installation Gap (IG) Calculator will help you identify the correct Installation Gap for your BFM® fitting installation.  The installation gap is the space to leave between the BFM® spigots and always needs to be slightly shorter than the connector length (CL).

You can download a copy of the calculator to use on a mobile device in the field or use it on-line, and you can also save your calculations as pdf files to refer to later.

The calculator is designed for installations with horizontal movement only - if vertical movement is also involved, please contact us for further guidance. 

The BFM® IG Calculator can be used on all standard mobile and desktop devices – simply complete the form to download or access the online calculator.
