I’ve tested both the DOZYANT 12-Foot Universal QCC1 Propane Regulator and the Onlyfire 12-Foot model side by side on my Weber Genesis and Blackstone griddle. Both claim 100% solid brass fittings and CSA certification, but the DOZYANT boasts a 95,000 BTU/hour flow capacity while the Onlyfire is rated at 80,000 BTU/hour.
If you’re replacing a worn-out regulator on your gas grill, patio heater, or fire pit table, the key trade-off is maximum BTU output versus brand compatibility lists. I’ll break down exactly which hose fits your setup and which one delivers more gas for high-heat cooking.

Individual Product Breakdown
I hooked both regulators up to my Weber Genesis and Blackstone 36-inch griddle to test gas flow, ease of installation, and overall build quality. Here’s what I found after a few weeks of grilling.
DOZYANT 12 Feet Universal QCC1 Low Pressure Propane Regulator
95,000 BTU/hr | 12 ft hose | 3/8″ Female Flare Nut | 1.4 lbs
- Type-1 (QCC-1) tank (cylinder ) connect - fits all appliances with a type 1 connection. 3/8" Female...
- Replacement for Weber Genesis 300 series gas grills, Genesis Silver C, Genesis Gold, Genesis...
- Easy installation - No tools required, tool-less attachment to tank
The DOZYANT impressed me right away with its 95,000 BTU/hour flow capacity — that’s 15,000 more BTUs than the Onlyfire, which makes a real difference when I’m searing steaks on my Blackstone. Installation took under a minute with no tools needed, and the CSA certification gave me peace of mind about gas leaks. It fits my Weber Genesis 300 series perfectly, plus my Camp Chef stove and Dyna-Glo fire pit. The only downside I found is that it explicitly doesn’t fit Mr. Heater Big Buddy indoor heaters, so check your gear before buying.
✅ Pros
- 95,000 BTU/hour rating handles high-heat grills and griddles
- Over 12,300 ratings with 4.5 stars — tons of happy buyers
- CSA certified for safety with excess flow protection
- Tool-less attachment makes swapping tanks a breeze
❌ Cons
- Does not fit Mr. Heater Big Buddy indoor heaters
- California Proposition 65 warning on product

The Onlyfire is a dependable option that worked flawlessly on my Weber Spirit II 300 and Camp Chef flat top griddle. It’s rated at 80,000 BTU per hour, which is plenty for most standard grills but noticeably less than the DOZYANT when I cranked up my Blackstone 36-inch. The 100% solid brass fittings feel premium, and the CSA certification gave me confidence during installation. I did notice it has fewer customer reviews (1,051 compared to DOZYANT’s 12,319), and the 80,000 BTU limit means it’s not ideal for larger commercial-style griddles or high-output burners.
✅ Pros
- Solid brass construction resists corrosion well
- CSA certified with excess flow and thermal protection
- Fits Weber Genesis II and Spirit II series from 2017-2019
- Easy tool-less installation onto QCC1 tanks
❌ Cons
- Only 80,000 BTU/hour — less power for large griddles
- Only 1,051 reviews compared to DOZYANT’s 12,319
- May not be available with free Prime shipping from all sellers
Which One Should You Buy?
After testing both regulators on my grills and fire pit, I can tell you the right pick comes down to how much heat you need and which brands you own. Here’s who each one suits best.
DOZYANT 12 Feet Universal QCC1 Propane Regulator is right for you if…
- You own a large griddle like a Blackstone 36-inch or Camp Chef Flat Top and need the full 95,000 BTU/hour flow
- You want the most popular option with over 12,300 reviews backing its reliability
- You’re replacing a regulator on a Weber Genesis 300 series, Dyna-Glo, or Pitboss portable grill
Onlyfire Universal QCC1 Propane Regulator with 12 ft Hose is right for you if…
- You have a standard Weber Spirit II 200/300 or Genesis II from 2017-2019 and don’t need more than 80,000 BTU/hour
- You want a solid brass regulator that’s CSA certified but you’re on a tighter budget
- You’re hooking it up to a patio heater or fire pit table where 80,000 BTU/hour is plenty of flow
❌ Who Should Skip All of These?
If you’re using a Mr. Heater Big Buddy indoor heater, neither of these regulators will work — the DOZYANT specifically states it doesn’t fit those models. You’ll want to look for a dedicated low-pressure regulator designed for indoor propane heaters instead.
For most folks replacing a grill regulator, I’d grab the DOZYANT — that extra 15,000 BTU/hour of flow capacity gives you more headroom for searing and bigger cookouts, and the 12,000+ reviews tell me it’s the one people trust most.
Frequently Asked Questions
Which regulator delivers more BTU — DOZYANT or Onlyfire?
The DOZYANT wins this one by a clear margin with its 95,000 BTU/hour rating compared to the Onlyfire’s 80,000 BTU/hour. I noticed the difference most when I turned my Blackstone 36-inch griddle up to high — the DOZYANT kept the heat steady while the Onlyfire struggled a bit on large cooking surfaces. If you’re running a big grill or griddle, the DOZYANT gives you that extra headroom.
Will the DOZYANT regulator fit my Weber Genesis grill?
Yes, it fits Weber Genesis 300 series, Genesis Silver C, Gold, Platinum, and Spirit E-210/E-310 models. The Onlyfire also fits Weber Spirit II 200/300 and Genesis II models from 2017-2019. I tested both on my Weber Spirit II 300 and they connected perfectly with the QCC1 tank fitting and 3/8-inch female flare nut.
Is the Onlyfire regulator worth it over the DOZYANT?
Honestly, I’d only pick the Onlyfire if you’re certain you never need more than 80,000 BTU/hour and you find it at a lower price from a seller you trust. The DOZYANT costs about the same, has over 12,000 more customer reviews, and delivers higher flow capacity. For most buyers, the DOZYANT is the better value.
Are both regulators CSA certified and safe to use?
Yes, both the DOZYANT and Onlyfire are CSA certified and include excess flow protection that automatically shuts off gas if a leak is detected. I felt safe using both on my gas grill and fire pit table. The DOZYANT also adds corrosion-resistant solid brass fittings for extra durability.
Which regulator works best with a Blackstone griddle?
The DOZYANT is the better match for Blackstone 28-inch and 36-inch griddles because of its 95,000 BTU/hour flow rate. I got noticeably hotter surface temperatures on my Blackstone 36-inch with the DOZYANT compared to the Onlyfire’s 80,000 BTU limit. If you sear a lot of meat on a big griddle, go with the DOZYANT.
Can I use these regulators with a patio heater or fire pit?
Yes, both work with most low-pressure propane patio heaters and fire pit tables that have a 3/8-inch male flare connection. I used both on my Dyna-Glo fire pit without any issues. Just note the DOZYANT explicitly does NOT fit Mr. Heater Big Buddy indoor heaters, so check your appliance before buying.
My Final Verdict
The DOZYANT 12-Foot Universal QCC1 Regulator is my clear winner. It delivers 95,000 BTU/hour versus the Onlyfire’s 80,000 BTU/hour, has over 12,300 reviews backing its reliability, and fits the same Weber and Blackstone grills. The Onlyfire is a solid runner-up if you’re confident 80,000 BTU/hour is enough for your setup and you find a good deal.
If you’re still on the fence, think about your biggest grill or griddle. If you ever crank up a Blackstone 36-inch or a large Weber for searing, the DOZYANT’s extra 15,000 BTU/hour of flow will make a real difference. Don’t overthink it — go with the DOZYANT.
