RS 5 gallon food grade container

I just noticed I said the female thread in the cap was 1/2". This is incorrect, it is actually 3/4".

Lol, I noticed 'someone' had posted a review and got the thread size wrong. Then I noticed it was me. :)

Really nice, sturdy dosing container. My biggest concerns were with piping options. So here is the low down on your options. The cap has a 1/2" NPT female thread in a recess in the center. So you can thread 1/2" male fittings into the cap, then drill a hole (in the recess) to allow access to the internals. There is also a venting hole. I am not sure what it is threaded with (either some unusual size or perhaps 3/8"). The hole in the vent nipple is slightly smaller than 1/4", so I plan to widen it slightly to 1/4" to a llow an RODI line to be snug, and then install a check valve as an air lock.

A solid, sturdy container. The opening is just large enough to accept my Tunze Osmolator pump.

As usual fast shipment and item as described. Ordered 5G and it works perfect as my ATO reservoir.
