Canadian Registration Numbers (CRN)

Canadian Registration NumberBoth Canada and the United States use the ASME Section VIII-1 code for pressure vessel construction but Canada has a CSA B51 standard that provides a more restrictive definition of what a PRESSURE VESSEL is. Canada also registers FITTINGS – items that other countries would be considered too small to need registering. Some our filters fall under the fitting category due to the small internal volume.

For a list of our housings that have CRN, please view our CRN page.   Canadian Registration Numbers

Keep in mind we are continually adding product to the registration roster.
