cant get my 3.5 liter amber PET,s anymore . 😥


1707515581930.png


at least i grabbed a half dozen plus i can still get the 2.5's
 
I'd like to have one of these to keep a gallon of homebrew upstairs, take with me, etc. Looks like the 4L with tapping head will fit on the door shelf of my fridge. For those who experienced leaks, is it primary just the prv or carb caps, or the tapping head itself that screws into the bottle.

I love the carb tee and caps Kegland sells, but on a 2L bottle it's too tall for my fridge.
 
Hey guys. Sorry it's taken so long to get the 4L Oxebar kegs over to you in America. We have been struggling to keep up with demand in Australia and generally we release products in Australia first. Some questions that have come up on the forum so far that I would like to clear up are:

How long will the beer last?
We use a barrier PET that uses Nylon as well as PET in the wall of this container that improves the gas barrier properties. The most oxygen sensitive beers a re light lagers and with these we recommend the shelf life in these kegs to be 3-4 months. For darker styles you can probably leave in the keg longer.

How have they been in terms of reliability?
They have been excellent in Australia and Europe with a large amount of positive feedback. With that said some issues have surfaced that I would like to point out. We did get a batch of faulty RED PRVs. I don't think any of these made it over to America but some of these leaked at very low pressures. In the off chance that you got one of these just make a warranty claim and it would be replaced. It was only a very small number so it's barely even worth mentioning. The only other issue we see are customers leaving the tip tube too long. We recommend cutting the dip tube so it doesnt rub on the bottom of the container when you screw on the tapping head. This can cause the dip tube to come off wile screwing up the head as the dip tube gets twisted. So it's important that when you get the tapping head make sure to cut the dip tube to a length where it can rotate freely. Beyond these two issues we have had the product received really well.

Will the tapping head work with other bottles?
Our PCO38 tapping head is based on the ISBT standard. The thread specification can be found here:
https://www.isbt.com/assets/Threadspecs/1165371-1_SHT1.pdf
Unfortunately this thread is extremely uncommon as very few other manufactures use a 38mm neck opening for carbonated beverages. You can probably see that the thread specifications quite similar to other 38mm necks so even though other 38mm neck finishes are manufactured by other juice bottle manufacturers and probably use a non-pressure rated thread it's possible that they may still work. I would recommend at least hydrotesting any container you decide to put under pressure if it's not designed for pressure as a minimum safety precaution.

If you guys have any other questions we will try to answer as soon as possible.
 
just got my 4 liter oxebars. these things are very high quality. they seem sturdier than a soda bottle. they take up the same footprint as a 5 liter mini and they are ultra light and see through.

ideal PET mini kegs. perfect for the kitchen fridge.

how do you reccomend cleaning them. first time and for reuse?

Thanks for the support we really appreciate it.

For cleaning:
PBW and water that is less than 45C in temperature. Also PBW contains Sodium Metasilicate. Always limit the contact time with PBW to 20min or less as if you leave PBW in contact with PET it will make the PET more brittle and can cause cracks to start.

For sanitizing
I would recommend using Star San or Stellarsan or some other phosphoric acid based sanitizer. You can leave this solution in the keg permanently for years and no damage will occur.

The tapping head (not the keg itself) is able to be put in the dish washer if you like.
 
I have the 8L bottles for half batches. The only issue I have is the bottles tip over very easily. Does anyone have a suggestion on stabilizing the bottles? Maybe some type of foot or bucket you put them in to keep them upright?

There are probably a hundred ways to DIY a simple stand to keep them from tipping over. Problem is that most of these would defeat a major advantage of the Oxebars - the small footprint. So I'm thinking velcro maybe.

When we first decided on the dimensions of these kegs we decided to make the diameter only 155mm so we could get a large number into a kegerator without taking up much floor space. With that said as you have suggested you can knock them over easily. One easy solution is to use this CO2 cylinder bracket:
https://www.kegland.com.au/products/2-6kg-co2-cylinder-bracket-holder-wall-mount

These fit the 155mm diameter oxybar kegs pretty well.
 
So I have a small chest freezer for my kegs. I think it's a 5.5 cubic foot model. The Oxebar 8L bottles fit perfectly in the opposite corners of the corny kegs. Try to ignore the mess but the upper right oxebar is sitting on the floor of the freezer. The lower left is sitting on 3 upside down 12oz paper coffee cups to raise it up. This is why I bought these kegs. I can do half batches or split a full batch. However, I have another small refrigerator that I occasionally use for beer and the Oxebar didn't do very well in that fridge.
Overall, I think the Oxebar kegs are the best small volume/introductory kegging system I've seen in the 15 years I've been brewing. (Remember the tap-a-draft).

I do like the Oxebar system as a low-cost solution, They work great most of the time. Great format and footprint, just need to be a little careful on concrete, and when cleaning that you don't flip a full one to dump(the vacuum will collapse it pretty quick). I can't wait to order some of the 4L ones.

I do see in the picture, that you thread-taped the connectors..Did that help get a better seal? Did you also tread-tape the keg? I have had issues getting the seal "just right", I didn't think of tread tape because I thought they had rubber gaskets, though now I'm going to have to check again.

Also, is there a recommended brand of ball-lock connectors with these? I've had hit or miss success, sometimes I have to hold the ball-lock connector down to get beer or gas to flow. I have mostly CMBecker, though I'm sure there may be cheapies in there too.

The PCO 1881 thread was designed as a bottle thread standard where it was a wedge seal where two smooth surfaces of rigid plastic seal against each other. No rubber or flexible material was used as flexible rubbers/elastomers are generally a weak spot and cause oxygen ingress as oxygen permiates through the seal. The carbonation caps should seal fairly easily when screwed onto the tapping head and the Polykeyton and PET connections make a very oxygen tight seal so you really should not require thread tape.

If you have a leak, one of the two surfaces is probably damaged and probably not smooth.

I did a pressure test with empty bottles before applying the tape and both held pressure for a couple of weeks while my beer was in the fermenter. The tape was added as a precaution after reading several reviews saying they had leaks. It's just enough tape to stay in place on the threads. About 1.5 wraps is all. All connections are hand tightened. No tools were used. As Kegland stated, there are no additional gaskets or o-rings in these connections.

Great. Thanks for that clarification.

Also even in the case of a leak the thread tape is probably not going to help this type of thread. As you can see from this type of thread design that was made by the ISBT:
https://www.isbt.com/assets/Threadspecs/1165371-1_SHT1.pdf

You can see the thread has a "vent" which is made up of vertical breaks in the thread. These breaks would prevent conventional thread sealers like thread tape from working. These threads with "vent" are designed to be safer so when the cap is unscrewed the gas from the pressure vessel can be release safely without the lid flying off.

I can attest to this, I made a stout back in November that I kegged in a couple Oxbars. I finished the last of the two kegs tonight and it still tastes great!
