The MK4 Regulator by KegLand provides a reading of keg dispensing pressure, as well as an accurate indication of cylinder gas level. By turning the chrome center knob, you can adjust the dispensing pressure from 0 – 100 PSI.  The MK4 features gauges housed in rubber to protect them from dings, as well as a large 2½" diameter diaphragm so it can both handle several kegs at once if needed, and the large diaphragm also lets you have precise control over the dispensing pressure (which you adjust with the center knob).

¼” flare outlet fits ¼" threaded flare beer lines or use the included Z93 Duotight tubing adapter to fit 8mm outer diameter EvaBarrier tubing.  Includes a 65 PSI replaceable safety relief valve. This regulator includes two nylon tank sealing washer, and will accept nylon or fiber tank sealing washers.

Excellent gauges. Can't beat them for the price.

Good gauges but

Review by Norm on 11/30/2016

I ordered this unit knowing, it did not have a shutoff valve with check. I ordered and installed (i91) on this regulator. Well the flair fitting for gas that was installed, was done with loctite! sooooooooo you may have a bit of trouble replacing it with the (i91 or Q87) valve. A second note: the chrome plating process used, pulled some zinc out of the surface of the brass fitting - when abused with the wrench to get the flair fitting off some chrome flaked off, leaving what looked like a copper fitting, but when cut a little deeper revealed the brass. Just a FYI to KegKing. So for the price, this seams to be a pretty good gauge, just know the parts were assembled using loctite which is good, and can be undone if needed, but is a pretty tough job and not much fun. It does look great, and mine had a spare gasket included, which is very nice. I would have given 5 stars but I had to bleed a little when removing the flair fitting (wrench slip you know) so only 4.

I really appreciate the gas connector on this regulator. Definitely designed for brewers. I recently bought a regulator at Harbor Freight for $36 and I had to take it back as the gas was leaking out of the pressure gauge. If you need a good regulator, I believe the Mark III is a great value and a great product. I only wish I would have purchased it when it was on sale.......LOL Slainte!

wish it had a shut off valve

Review by stan macias on 7/31/2017

this is a very nice regulator. the adj. knob is far superior to micro matic which seam to strip the threads out of the adjuster if left in a fridge. this design with a plastic knob will never happen. I wish they had a shut off valve though. and its not easy to mount a valve because the threads are metric because it was made in Australia. my only complaint, the product functions perfectly for my use

Q: If you want to put a shut off on the regulator what do you suggest would work as it is metric? And does williams sell this item?

A: This would be easy if you went Duotight with this and used ball valve X27. You can also unscrew the bottom outlet and install something like our item Q87, although they are very difficult to unscrew, as they are put in with thread locker.

Q: What is the input pressure of these regulators i.e. the C02 Cylinder Pressure. The Cylinder I'm looking at is 200psi and I just wanted to check that this regulator would be sufficient for that?

A: 200 PSI seems pretty low for a Co2 tank as most 5lb Co2 tanks will be closer to 800 psi when full at room temperature and 600 psi when stored cold. This regulator will have no problem dealing with 200 psi safely.

Q: Since this is a "multi-gas regulator" can it be used for 75% Nitrogen/25% Co2 mix, 100% Nitrogen, or 100% Argon if the correct conversion piece is applied?

A: Yes, although we do not have the correct conversion pieces for USA spec tanks.

Q: These are supposedly multi-gas regulators. Can we order the type 50 converter for nitrogen from Williams?

A: No, because the converters are currently made for Australian standards, and will not fit American Nitrogen bottles.

Q: Can you hook up one of the multi-port gas manifolds directly to the regulator's 1/4" output?

A: Yes, although you will need a 1/4" NPT nipple which we do not sell, and keep in mind the gas outlet is secured with a lock tight type compound, so you may want to see how easy it is to remove before starting on this.
