Filter May Crack with Over-tight Fitting

Use Hands

The inline alkaline filter (ALK1-2512-I) has a clear housing, which is fragile. It also has FNPT threads at both ports.  Please, tighten a fitting by hand and then use a tool to engage fitting an additional one turn. Do NOT attempt to force the male connector fitting in the port; do NOT over-tighten fitting as this may cause the filter to crack or damage the threads! It is only necessary to tighten fittings enough to prevent leakage. Use care when using Teflon tape as friction is reduced considerably; If leaks occur, remove connector, clean off old Teflon tape, re- wrap with two or three additional layers of Teflon tape, and re-install connector.
