McDantim In-Line Leak Indicator
Find Gas Leaks in Seconds. Stop Wasting CO₂, Nitrogen & Money.
If you’re losing gas, you’re losing profit.
The McDantim In-Line Leak Indicator instantly shows you whether your draft beer system has a leak — and how large that leak is — regardless of your gas source, system size, or complexity.
One quick glance tells you everything you need to know.
Why This Matters
A leak as small as ½ cubic foot per hour wastes more gas each day than it takes to dispense two full kegs of beer.
That’s:
-
Wasted CO₂ or Nitrogen
-
Increased gas bills
-
Poor carbonation performance
-
Inconsistent pours
-
Unnecessary service calls
With this simple inline device, you’ll know immediately if gas is flowing when it shouldn’t be.
How It Works
When you’re not pouring beer:
-
Ball resting at the bottom → No leak.
-
Ball lifted in the tube → Gas is flowing. You have a leak.
-
Higher ball position → Larger leak.
It’s that simple.
Check it before your first pour of the day or after your last pour at night. If there’s movement, you know action is required.
As you repair leaks, the indicator becomes your scorecard, confirming when the issue is fully resolved.
Essential for Nitrogen Generator Systems
Leak detection is even more critical in systems using nitrogen generators.
Leaks in these systems:
-
Waste gas and electricity
-
Force compressors to run continuously
-
Shorten compressor lifespan
-
Lead to costly rebuilds or replacements
A small investment in leak monitoring protects expensive compressor equipment.

Stop Leaks Before They Cost You
Gas leaks are:
-
Dangerous
-
Expensive
-
Easy to miss without the right tool
The McDantim In-Line Leak Indicator gives you immediate visibility into your system’s health — helping you prevent wasted gas, protect equipment, and maintain consistent draft performance.
Know before you pour.
Why Buy Now?
Every Day You Wait, You’re Paying for Leaks.
Gas leaks don’t fix themselves.
They quietly drain your CO₂ or Nitrogen supply, increase utility costs, and stress your equipment — all while you pour beer like nothing’s wrong.
Even a small ½ cubic foot per hour leak can waste more gas in a day than it takes to pour two full kegs of beer.
That’s money literally leaking out of your system.
Protect Your Gas. Protect Your Equipment.
If you run:
-
Nitrogen generators
-
Blended gas systems
-
Multi-regulator setups
-
Long-draw systems
Undetected leaks can force compressors to run continuously — leading to premature failure and expensive repairs.
Replacing a compressor costs far more than preventing the damage in the first place.
It Takes Seconds to Check — and Could Save Thousands
One glance:
-
Ball down → You’re good.
-
Ball floating → You have a leak.
No electronics. No testing kits. No guesswork.
Just immediate confirmation before your first pour or after your last.
The Smart Operator Checks Daily
The difference between profitable draft systems and costly ones often comes down to visibility.
If you care about:
-
Lower gas bills
-
Fewer service calls
-
Longer equipment life
-
Consistent pours
There’s no reason to wait.
