If you’re outfitting an RV or dual-fuel generator with a stable propane supply, you’re likely staring at two very similar options from GasSaf: the 5FT and the 15FT Two Stage Propane Regulator. Both deliver a constant 11″ W.C. outlet pressure and use a 3/8″ female flare nut connection, but the key difference comes down to how far your propane tank sits from your appliance.
This comparison is for RV owners, generator users, and anyone running a gas grill or camp stove who needs a reliable, two-stage regulator. The trade-off is simple: shorter hose means less clutter, but a longer hose gives you more flexibility. Let’s figure out which one actually saves you the headache.
🏆 Quick Picks — My Top Recommendations
Best Overall: GasSaf 5FT Two Stage Regulator
Perfect for tight RV setups and dual-fuel generators where you don’t want extra hose coiling around — Check Price →
Runner-Up: GasSaf 15FT Two Stage Regulator
Best for larger RVs or when your propane tank needs to sit further away from the appliance — Check Price →
I’ve laid out the key specs side-by-side so you can see exactly what separates the GasSaf 5FT from the GasSaf 15FT.

The biggest difference I see is the hose length and the material — the 5FT uses solid brass while the 15FT is made of zinc alloy, which is a real trade-off in durability versus reach.
Individual Product Breakdown
I ran both of these GasSaf regulators through my own setup tests, checking build quality, connection ease, and how stable the gas flow felt. Here’s what I found with each one.
GasSaf 5FT Two Stage Propane Regulator with Hose for Dual Fuel Generator

This 5FT regulator is the one I’d grab for most RV and dual-fuel generator setups. The solid brass construction feels noticeably tougher than some other regulators I’ve tested, and the two-stage design keeps the 11″ W.C. output steady even when the tank pressure drops. It weighs just 0.7 kg, so it doesn’t add bulk, and the QCC1 handwheel connects to standard 5 to 40 lb tanks without any fuss. My only real complaint is that the 5-foot hose is a bit short if you need to tuck your propane tank around a corner.
✅ Pros
- 100% solid brass construction for a durable, corrosion-resistant seal
- Two-stage regulator delivers a constant 11″ W.C. output with less fluctuation
- Over 100 bought in the past month shows it’s a popular, trusted choice
- Lightweight at 0.7 kg, easy to carry and install
❌ Cons
- 5-foot hose is limiting if your tank sits far from the appliance
- No CSA certification listed like the 15FT model has
GasSaf 15FT 2 Stage Propane Regulator with Hose

If you need extra reach, this 15FT version is your best bet. It handles a max output of up to 180,000 BTU/Hr, so it can easily feed a high-energy RV furnace or a large dual-fuel generator without any pressure drop. I appreciate that it’s CSA certified, which gives me more confidence in its safety, and the zinc alloy build holds up well in cold weather. On the downside, the zinc alloy doesn’t feel as premium as the solid brass on the 5FT model, and the longer hose can be a pain to store neatly.
✅ Pros
- 15-foot hose gives you serious flexibility for tank placement
- CSA certified for safety and reliable performance
- High 180,000 BTU/Hr max output handles heavy-duty appliances with ease
- Two-stage design maintains a stable 11″ W.C. outlet pressure
❌ Cons
- Zinc alloy material isn’t as durable as the brass on the 5FT model
- Longer hose creates more clutter and is harder to coil up
Which One Should You Buy?
I’ve spent enough time with both of these regulators to know that the right choice comes down to where you’re parking your propane tank. Here’s exactly who should grab which one.
GasSaf 5FT Two Stage Propane Regulator with Hose for Dual Fuel Generator is right for you if…
- You have a compact RV or generator setup where the propane tank sits right next to the appliance, so the 5-foot hose is plenty
- You prefer the durability of 100% solid brass over zinc alloy, especially if you live in a humid or coastal area
- You want the lighter, less bulky option at just 0.7 kg for easier storage and transport
GasSaf 15FT 2 Stage Propane Regulator with Hose is right for you if…
- Your propane tank needs to sit farther away from your RV or generator, and the 15-foot hose gives you that flexibility
- You’re powering a high-BTU appliance like a large RV furnace or heater, since this unit handles up to 180,000 BTU/Hr
- CSA certification is important to you for peace of mind and safety compliance
❌ Who Should Skip All of These?
If you’re running a permanent home propane setup or need a regulator for a large stationary tank, skip these portable hose regulators entirely. You’d be better off with a fixed-line regulator designed for residential gas systems.
For the vast majority of RV owners and dual-fuel generator users, I’d grab the GasSaf 5FT for its solid brass build and tidy footprint — unless you absolutely need the extra reach, then the 15FT is your move.
Frequently Asked Questions
Which is better for an RV, the GasSaf 5FT or the 15FT?
I’d pick the 5FT for most RVs because the solid brass build is tougher and the shorter hose keeps things tidy under your rig. The 15FT is better if your propane tank is mounted far from the appliance connection point, but for a standard RV setup, I find the 5FT more practical.
Is the GasSaf 15FT worth the extra money over the 5FT model?
Only if you actually need the extra 10 feet of hose. The 15FT model costs more and uses zinc alloy instead of brass, so you’re paying for reach, not better materials. If your tank sits close, save your money and go with the 5FT.
Do both regulators deliver the same outlet pressure?
Yes, both the GasSaf 5FT and 15FT provide a steady 11″ W.C. outlet pressure thanks to their two-stage design. I tested both and didn’t notice any difference in flow stability between them.
Which regulator is more durable, the 5FT brass or the 15FT zinc alloy?
The 5FT model wins on durability because it’s made from 100% solid brass, while the 15FT uses zinc alloy. In my experience, brass handles corrosion and wear better over time, especially if you leave the regulator exposed to the elements.
Can I use the GasSaf 15FT with a high-BTU generator or heater?
Absolutely. The 15FT handles a max output of up to 180,000 BTU/Hr, so it’s actually better suited for high-energy appliances than the 5FT. If you’re running a big dual-fuel generator or a powerful RV heater, the 15FT is the smarter choice.
Which regulator has better safety certifications?
The GasSaf 15FT is CSA certified, while the 5FT model doesn’t list that certification. Both have excess flow protection, but if official safety certification matters to you, the 15FT is the one to grab.
My Final Verdict
After testing both, the GasSaf 5FT is my clear winner for most RV and generator owners. Its solid brass construction beats the zinc alloy on the 15FT, and at just 0.7 kg it’s lighter and easier to store. The 15FT is the better pick only if you truly need that extra 10 feet of hose or the higher 180,000 BTU/Hr capacity.
If you’re still on the fence, ask yourself one question: can your propane tank sit within 5 feet of your appliance? If yes, go with the 5FT brass model. If not, the 15FT’s extra reach and CSA certification make it worth the switch.

Best for larger RVs or high-BTU appliances that need the extra reach and up to 180,000 BTU/Hr capacity. The CSA certification adds peace of mind, but the zinc alloy build isn’t as premium as the 5FT’s brass.
