Product Questions & Answers

Got a tank with no cleanout plate or interior access -- can this thing still be mounted from outside without tearing into the reservoir?

Question by: Ricky M on Apr 2, 2026, 12:39 PM

Front mount style A is built exactly for that situation. As long as the tank wall is thick enough to tap threads, you can install it from the outside without ever needing to get inside the reservoir. It also allows a 1/16 inch alignment adjustment, so if your holes don't line up perfectly you've got a little wiggle room to work with. If you do happen to have interior access, it can go in that way too using the furnished nuts.

got a tank i cant get inside of. can this sight glass be mounted from the outside?

Question by: Neil P on Aug 12, 2025, 9:35 PM

For reservoirs with no interior access, the front mount construction lets you install it from the outside as long as the tank wall thickness permits tapping. It also has about a 1/16 inch alignment adjustment to help you line it up during mounting.
