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 diaphram so it can both handle several kegs at once if needed, and the large diaphram also lets you have precise control over the dispensing pressure (which you adjust with the center knob).

Threaded ¼” flare outlet fits our D03 Gas Connector (no need to adapt your ¼" gas tubing to fit the 5/16" wide hose barb found on other beer regulators).  This connector also fits the DuoTight Flare Fitting (our item Z93).  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.

It leaked
I went through several cylinders before I discovered it leaked internally.  Next time I'll step up to a better product.

wish it had a shut off valve
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

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

Good gauges but
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.

These are supposedly multi-gas regulators. Can we order the type 50 converter for nitrogen from Williams?
No, because the converters are currently made for Australian standards, and will not fit American Nitrogen bottles.

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

This came with 2 nylon washers that appear to be specific to this unit - are these reusable or should I replace the washer each time I change out the gas?
These are reusable and should last a while.

Can you hook up a gas line directly to the regulator that has the swivel nut on the end of the gas line?
Yes, remove the swivel nut and the regulator has a male ¼" flare thread, to accept our D03 and other threaded gas lines. You can also hook up ¼" interior diameter gas tubing, we recommend you use our D87 Concave Washer to seal the included hose barb fitting.
