Question by: Melvin H on Sep 27, 2025, 9:47 PM

got a tank where i can’t reach the inside worth a darn. will this sight glass mount from the outside?

For reservoirs with no interior access, the front mount style lets you install it from the outside as long as the tank wall thickness permits tapping. If you do have inside access, it can also be installed using the furnished nuts.

Question by: Hubert T on Apr 2, 2026, 9:19 PM

Does this sight glass have to be installed from the inside of the tank, or can you put it in from the outside?

Answer by: Customer Support on Apr 4, 2026, 7:15 AM

Front mount style means you can install it from the outside of the reservoir without ever needing to reach inside. That comes in real handy when the interior isn't accessible. If you do happen to have inside access, it can also go in with the furnished nuts. Either way works. There's also a 1/16 inch adjustment built into the construction so you've got a little wiggle room to get it sitting straight on the wall.
