I'm not sure if I posted this in here before but I bought the weld-less bulkhead and 3 piece valve from brewhardware.com to make mine and didn't need any washers or use the original rubber washer. Works like a charm

Hi all,

I am trying to create MLT from 10 gallon rubbermaid cooler. I cannot completely fasten the female brass adapter (Watts A-298) to the 3/8'' MIP brass nipple (Watts A-786)

I have a gap between these two. It looks similar to the FlyGuy's picture:



But on one of the last pictures he does not seem to have this gap anymore when he added external parts



How to screw this so I do not have that gap between A-298 and SS washer?
I assume that I do not just pull the whole thing outside because the flat part of Watts A-786 will be out of the cooler and I would be unable to secure it in place.

Thanks.

You will probably have to use multiple ss washers to make up the gap. If memory serves me I used something like 3-4 washers and it seals perfectly.

So I have to use 3-4 SS washers inside and 3-4 outside? Thanks a lot.

I only used them on the outside. one on the inside if I remember correctly I would take a look but it is outside in my garage.

I just did this using 3 SS washers outside plus 1 ss inside. Leaks a few drops a minute or so but I think my cooler has a thinner wall so I will need to get more washers to make up for the lost thickness.

Mine is a blue Lowe's igloo cooler.

So if there is only one washer inside, do you move the washer all the way?
I am asking this because I was not able to screw Watts-298 all the way to the washer. There is a gap (you can see it on the first picture in my first post) between Watts-298 and washer where you can see the teflon tape.
I do not know how you were able to screw it all the way to the washer.

I don't know what you mean by 'move the washer all the way'.

Basically you need enough washers so that you can screw it tight, it doesn't really matter too much whether they're inside or outside as long as you can screw the inside barb on so that you have some good force against the cooler wall.. Maybe the brass nipple you got is a little long for your cooler so you need a lot of washers. It's kind of hard to tell what's going on though without actual pictures... it'd also help if you call them 'nipple' and 'hose barb' instead of 'Watts 298'.

With my build, the initial washers that I bought didn't fit over the unthreaded part of the nipple. This caused the nipple to move forward and backward. I had to buy different washers that fit over they unthreaded portion of the nipple (slightly larger inside diameter). Both washers were sold as the same size, but the inside diameters varied. This allowed me to tighten everything properly with no leaks.

I don't completely understand your issue, but I thought this might help.

I marked on the picture where the teflon tape is still visible. The washer cannot go any further. It reached the flat middle. And I cannot screw the nipple further either. All the people seem to have just one washer on the pictures. So I am confused as to why it is not working for me and what I need to do.
