Make/Model:                          Model C1413, Article Number 620172.3

 

FM Approval Status:            Currently FM Approved

 

Hazard Involved:  The defect consists of an incorrectly applied zinc coating which may chip or flake off while in service.  There is a possibility that, without the proper zinc plating, the pipe fitting may be subject to accelerated corrosion. Additionally where a large number of the fittings may be used in a system, the accumulation of zinc flakes could possibly cause an obstruction to sprinkler water flow.

 

It is recommended that these compression type pipe fittings be removed and replaced with new product supplied by VSH.  If there is any doubt regarding the identification of a compression type pipe fitting, seek advice from the pipe fitting supplier or directly from VSH Fittings B.V.
