An ideal solution if you want to serve different beers at different gas pressures. In a typical multiple line, multiple pressure system you would run a gas line from you main regulator into a secondary regulator where you would set different pressures. While that is ideal it is a little pricey. This little sweetheart lets you set different pressures at a far lower cost. What we do is set the main regulator at the highest pressure we want in the system - for example a keg of soda that you want to carbonate and serve at 25 psi.  Run the gas line into a manifold and then install one of these after the manifold on each line where you want to decrease the pressure, for example lowering to 10psi to serve your British pale ale and 14 psi to serve your summertime lawnmower lager.  

While this unit does not have a pressure gauge you can use an adjustable relief valve/spunding valve on your keg to tell the pressure. Pressure adjusments can be made with a screwdriver.  

The maximum inlet pressure is 150 psi. Made from non corrosive acetyl, nitrile, and stainless parts. The regulator comes with two brass barbs to fit 3/16" tubing on. Alternatively, you can remove the barbs and use 1/4" OD tubing directly on the regulator. The aluminum manifolds linked above feature 1/4" barbed outlets and are a good match with this regulator. 

Can also be used with liquids.  


  • Works with 0 - 150 psi
  • Works with both gas and liquid
  • Comes with two brass barbs
  • Has two mounting points
  • Made from non corrosive acetyl, nitrile, and stainless parts

Kenneth S on Mar 1, 2020
I have them, and they work well. One of them must have been defective becuase it blew the top off at 35psi. It didn't leak gas, but it was no longer adjustable. These are a replacement and backup.

"you can remove the barbs and use 1/4" tubing directly on the regulator." Does this mean the regulator has built in duotight/JG/PTC type fittings? So for 1/4", no nipple or clamps needed? If so, what tube OD works, as that is what is usually specced for that type of fitting? Thanks
jeff royster on Sep 13, 2019
BEST ANSWER: Hi Jeff - Yes, the regulator features Duotight type push-in fittings. 1/4" OD tubing can be connected directly.
Can I use the KegLand EvaBarrier 8mm OD tubing with these directly as a push in line? If not, what is required to get these in line with EvaBarrier tubing and DuoTight fittings?
Lance Parsons on Jan 10, 2020
BEST ANSWER: Hi Lance - unfortunately 8mm OD EVABarrier is too large to work with this unit. However, the D1047 in-line regulator is sized for 8mm EVABarrier.

How do I connect this to standard 5/16" gas tubing?
Looks like I need to buy 5/16" to 3/16" reducers, then 3/16" tubing. Is there an easier way?
Stephen Stoyanov on Aug 13, 2020
BEST ANSWER: I heated 3/16 ID X 5/16 OD Polyethylene tubing in boiling water. Pushed that on then the 5/16 gas tubing over that. Secured with Oetiker clamp. Zero leaks.
The packaging says this product contains lead. Is that just the barbs or some internal component?
raun m krisch on Jul 23, 2020
BEST ANSWER: The warning is related to California's Proposition 65. Any brass item, even brass items made from "lead free" brass, have enough lead to require a warning in California. Brass is commonly used in gas sytems as it does not come in direct contact with your beverage.
Can the 3/16 barbs be replaced with 5/16?
Steve P on May 5, 2020
BEST ANSWER: I believe they are 1/4" not sure how you would change the size. If you have a lathe you could turn 1/4" x what size you need.
Does the In-Line regulator prevent backflow?
Gary Haygood on Feb 19, 2020
BEST ANSWER: No regulator inherently prevents backflow, hence the need for a check valve if this is a concern. Also, if you are getting backflow into your regulator you should consider increasing your psi.
What is the pressure range of adjustment?
jamie kopf on Nov 9, 2019
BEST ANSWER: Hello Jamie, the working pressure is 0-150 PSI.
This id not have any instructions. Is there a resource to show how to adjust these regulators? A youtube video would be helpful.
Richard Winblad on Feb 8, 2021
BEST ANSWER: Just turn the plastic screw on top. Either by hand or I believe a Phillips.
Are these impervious to liquid beer? I ask because the suggested install has them between the keg and the manifold, which usually has check valves to protect "normal" regulators. Thanks
jeff royster on Sep 13, 2019
BEST ANSWER: Hi Jeff - These work with both gas and liquid, so no check valve would be present.
What part/connector do I need to buy in order to connect this to a cheap low pressure valve like D1088? Would 3/8" Barb x 1/4" Female Pipe work?
JAYSON J KNACK on Apr 11, 2019
BEST ANSWER: Hi Jayson - We do not carry a "T Manifold Assembly" like in the picture for the D1045 but a D1820 with the 1/4" FPT should allow you to add the D1088 which would connect to the D1045.

Fine, but inconvenient with Evabarrier tubing - Ports accept 1/4 line
These are ok, certainly a great inexpensive option if you are using pvc tubing for your CO2. I switched to 5/16 8mm Evabarrier. As another poster mentioned along with the item description, you could slip 8mnm evabarrier over the metal ends(I'm not calling them barbs, because they aren't). I'm not a fan of doing that, as I worry about what it does to the inner evabarrier lining. I'm really not a fan on these particular valves because the brass pieces aren't actually barbs, they have nothing to bite into the tubing, so friction and clamps are the only thing keeping them from popping off and emptying your CO2 out. I ended up ordering 5/16 to 1/4 duotight reduicers to solve this with duotight, but if even the slightest lateral pressure on where the reducer meets the brass nipple will cause a leak. Pretty sure it's emptying my bottle as we speak, but it was close to empty anyway.

Another thing is that while the working range is huge, that makes the adjustment very touchy. Once you're near beer pressures, turning a 1/4 turn will get you up to 50 PSI or so, so they are a little tough to dial in(though they can absolutely dial in just fine).

Not a fan for my setup, but they are super cheap and effective. Posting this as I come on the site today to order the Kegland regulators with minigauges, as the lack of gauges on these was also inconvinient. If you have shutoffs on each line or a couple spare kegs to get a gauge on there easily, then no big deal.

Great product at a great price
Great little item to step my normal 12psi keg pressure down to 5psi for an English Ale. I made up an adaptor between the John Guest quick-connect and my spunding valve so I can set the pressure and then hooked it to the keg. It’s compact in the tight confines of my four keg kegerator and works well.

Learn from my mistake.
I thought the barbs in this could be removed (Yes), revealing standard 8mm ports for evabarrier tubing (No). Alas, I cannot get 8mm tubing in it. The ports are smaller...You could push 8mm over the barbs but I did not want to use clamps. The version 2 inline regulators work like I wanted. I got some of those. Two stars because the reg may work fine - your needs may be different. Do wish it had a knob like the newer ones, though!

Works great - great price. Unscrew to reduce pressure
A sentence or two of documentation would bump these to a five star product but as it is you have to guess how they work. Unscrewing the adjustment screw (counter clockwise) reduces the pressure in the output line. Which in my mind was a bit counter-intuitive. While I was unscrewing it, I was worried I was going to go too far and the whole piece would pop out with springs and gaskets flying all over and CO2 blowing in my face, but it didn't.

Good for the price
I needed a secondary regulator to carb sparkling water at a different psi than my beer, without using a second tank. I worked this into my keezer and it did the trick. I've noticed a slight bit of drift once in awhile, but overall it's been working well for the last few months and for how inexpensive it was I can't complain.

Seems to work, could have more documentation
Got this to allow soda and beer pressure with a simple setup. Installation was pretty straightforward, just make sure to note the flow direction arrows.

The package doesn't come with any directions or specs which could have helped with the following:

- The two tiny blue clips presumably get wedged between the housing and the white plastic collar that holds the brass insert.

- To reduce pressure, turn the knob Counter-Clockwise, which could be easily indicated with some simple markings.

- Changes in the input pressure don't change the set output pressure (I set output at 13psi and changed the input pressure from 25psi to 32psi with no output change).

Great product
These are great in line regs, they are pretty sensitive when adjusting so go slowly when setting them up.

Fairly handy items
These took a bit of time to dial in and I still question how dialed in I really am. I use my spunding valve with 30psi dial to be able to set one valve at 25 for soda and water while having 3 other valves set to 8, 10, 12 for other beverages. So far I think it works well enough but I’ve only run 3 kegs through the system. I used the CO2 bottle holder bracket screw to hold my 4 valve manifold. The plan was to mount these valves to the wall with Velcro tape but the tape doesn’t stick the the valve due to low surface area contact. I think I’ll just let them hang as it will make removing them a bit easier if needed one day.

Worth the effort
The guy that said useless is probably useless. Works great. I may be wrong but to set the pressure I set main at the pressure i wanted. Turned off the single reg. Slowly turned it on and let it equalize. I repeat that until it stops taking co2. Should be pretty close to desired pressure. 5 star
