Johnson Controls F93B-1 Control

why is mine leaking around the brass nut and what do I do to fix it.

Hi, it could be the nut or the connector thread is damaged. You could try the product listed below if that doesn't fix it you need to replace the valve or the connector. Thanks.

Should I tighten the brass nut that is leaking air?

Check if the brass nut is threaded or glue to the control. If threaded you could try gently but be careful not to break it in the process.

Is the threaded fitting made of steel or plastic?

It says the body is made of Noryl, but not sure if that includes the threading.

Our F93B-1 float valve needs to be replaced but the one that was brought in for us does not have a threaded brass connector with an attachment to attach a plastic tube to vent the gas from the tank out a window as our well lets off methane gas through the pump into the tank. Do you have the correct float for us? Or do we have to replace the brass nut on the bottom to accommodate the adapter for the hose?

Please see below tech sheet for some of the parts available for this valve. Thank you.

my tank became waterlogged. Is this part the issue? I drained and refilled it and it is working normally now but my concern is if this part has failed, it will become waterlogged again.

Hi, it is hard to pinpoint where the problem is without checking it out in the field. It could be this part or something else so it is best to have a contractor take a look. Thank you.

What is the difference between a F93B – one and an F93B – 1C
