Flexible Hoses are LPCB Approved for use in wet systems only.
Only LPCB Approved pendent spray sprinklers of 10-mm, 15-mm, and 20-mm nominal diameters with
K-factors of 57 and 80 shall be used.
Tested with a 5 3/4-inch/146-mm length straight reducer.
When using a No. 101 90° Elbow or a No. 102 Straight Tee in place of a Style 108 Coupling on the end
of a Series AH1-CC or AH2-CC Flexible Hose, the friction loss data shown above shall be added to the
No. 101 or No. 102 friction loss data published in Victaulic
