5G food grade container

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.

Advantages: Sturdy. Sensible connectivity options as default.

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

Advantages: Compact, takes less space than a 5gal bucket.

Disadvantages: It will be difficult to clean the interior.

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