## Overview

The Kegco KC LH-542 is a premium commercial-grade dual gauge CO2 regulator designed for home and professional draft beer systems. Featuring forged brass construction, dual gauges for PSI and CO2 volume, a tamper-proof safety relief valve, and an easy-to-use large adjustment knob, it delivers precise carbonation control and reliable safety. Compatible with any CO2 tank with a CGA-320 valve, this regulator is ideal for craft beer enthusiasts and home carbonation aficionados seeking durable, professional performance at an unbeatable value.

## Description

The Kegco 542 Pro Series works with any CO2 tank with a CGA-320 valve and measures psi, as well as the volume of the CO2 gas in the cylinder. The regulator body is constructed of forged brass with all brass Connections and components, a sintered brass inlet filter, integrated nylon tank Connection washer (and spare) And self resetting safety release valve. Both gauges feature an easy to read design. The top gauge lets you know how much CO2 pressure is in the keg and displays 0-60 psi. The second gauge lets you know how much CO2 gas is left inside the CO2 tank and features a 0-2000 display. A large adjustment knob with a lock ring allows gas flow to be changed without the need for a screw driver. This regulator includes a tamper proof safety pressure relive valve that releases at 45 psi. There is also a shut off valve that allows for instantly shutting off pressure to the keg without backing up your gas line.

Review: 2nd time a charm - I purchased this regulator to make carbonated water at home. We don't drink pop (soda for the non-midwesterners), nor beer. But my kids like H2O type water. So I use this to carbonate 2 liter pop bottles very inexpensively. The first one that I got had a bent faceplate on the low-pressure gauge. This prevented the needle from going any higher than about 30 psi. I carbonate at 40psi. So I took off the cover to that gauge and bent the metal faceplate backwards to clear the needle. It appears that the two little holes for the mounting screws were improperly located, making the faceplate higher than it should be. Then after 2 months, the pressure regulator part started not working correctly. It would keep rising pressure until the relief valve dumped pressure. I knew that this meant that it hit the limit of about 50 psi and then dumped. I emailed the company that sold the product, through the desertcart contact seller link, and they apologized and sent out a replacement regulator. I received the replacement regulator within about a week, and this one seems to be working fine. Time will tell if it starts not regulating, but at least this faceplate is not bent and the needle works just fine. But for now, we love having very inexpensive carbonated water around. My estimate is upfront cost of the regulator, the hose, or the ball-lock connector, or the ball-lock 2-liter top, or the purchase of a CO2 tank (i bought a 20lb tank), totals to be about $175. This is compared to a soda stream at about $100. But with a 20-lb CO2 tank, people report they can fill somewhere between 1000 and 1500 2-liter pop bottles of water before having to recharge. Since a recharge is about $20, that brings cost per 2-liter bottle down to about $0.02 per 1.5-liters. Considering that 130-liters of sodastream charge runs about $60, that's about $0.50 per liter! Sure, mine doesn't look as pretty, and can't sit on a countertop, but it sits in our furnace room just fine. I fill about 4 2-liter bottles at a time and store them in the fridge.
Review: So Far So Good - Home Carbonating my own soda - I will preface my write up by saying that I am not a beer brewer, so please consider my use is simply carbonating water for use in home bottled soda. I was a soda stream user for a long time and between price hikes and product changes I decided to go another way. Now I purchase either coke bag in box or similar "off brand" Bib syrups from local distributors. I use this with a 5 pound mini tank in my garage and almost exclusively carbonate water. In the last 5 months I've carbonated at least 200 1 liter bottles of water without issue. I have noticed that the emergency release vale can be a little sensitive, i.e. if I bump the tank or tug the line a bit too much while agitating my 1 liter I have a time or two caused the valve to pop. It's a simple quick fix of pushing it back in and I guess realistically I would rather it be too sensitive then fail to function in a failure situation. Other folks have commented about the cheap quality, I honestly don't feel it has a cheap feel but I wonder if folks aren't comparing this to more high end beer brewing equipment... In context that would be like saying a Kia (or even a Honda) is "cheap" because it's not as nice as a Bugatti. As an entry level gauge this thing has performed for me just fine, my unit did not come with any shipping damage and has functioned great for my purpose of carbonating water to be used with soda syrups.

## Questions & Answers

**Q: Is there any way to add an additional regulator so that two different pressures can be set? http://www.amazon.com/gp/product/B003WXBD4O**
A: Yes, remove the hi pressure gauge and put a 1" or 2" extension pipe where the gauge was. Make sure that the threds on the extension are going the right way. They will be left or right. Than add the second regulator to the end of the extension.

**Q: Is there a handle I can add to the hex knob to make it easier to adjust the output pressure?  Right now I'm using a wrench.**
A: My Kegco came with a dial for the pressure.  It has a plus and a minus on it and that is where I adjust it (see the picture).  If you did not get this knob then most likely you would have to use a wrench or screw driver.  On the old regulator I did have to use a screw driver and the adjustment was hard to make.  If you don't have the new Kegco regulator it is worth the purchase.

**Q: Is this regulator cheap in quality and will it continually leak co2 after one use?**
A: It does not leak, but the gauge and/or the release valve is inaccurate. Sometimes I could wind the pressure up to what the gauge said was 50 PSI with no problems, other times, the release valve would activate at that level. And sometimes the valve would blow at lower PSIs, so the gauge would read 40 PSI but the release valve would engage. For the record, I believe the documentation says the valve should engage at 45 PSI. I don't remember. I ended up buying a regulator from www.micromatic.com, and have been much happier with it.

**Q: Where can I get a compatible gauge protector**
A: This should work. http://www.beveragefactory.com/draftbeer/regulators/cages/WGC.shtml
