This 12-foot assembly is built to match the F273684 specification often found on portable buddy heaters. It includes a two-stage regulator for stable low-pressure output and brass couplings designed for long-term leak resistance.

• Regulation: Two-stage regulator for smoother gas flow to low-pressure heaters.
• Material: Rubber hose with solid brass coupling components for corrosion resistance.
• Compatibility: Uses P.O.L. interface, suitable for 20–100 lb tanks and common heater models.
• Intended Use: Designed with portable heaters and RV appliances in mind.

When connecting a propane heater that specifies an F273684 part number, this hose/regulator combination matches manufacturer-style interfaces and provides controlled low-pressure delivery appropriate for indoor-rated or portable heaters.

Mr. Heater F276124 5′ Hose

Check Price on Amazon

The Mr. Heater F276124 is a short, purpose-built 5-foot hose assembly featuring 3/8″ male pipe thread x 3/8″ female pipe thread ends. The hose material is stretch-tested to a high PSI level, intended for secure, durable connections between low-pressure appliances and regulators.

• Short Run Reliability: Five feet minimizes potential leak points and pressure drop.
• Thread Type: 3/8″ male and female pipe threads common on many heater regulator hookups.
• Durability Tests: Hose stretch-tested to 400 PSI, indicating robust construction for safety margins.
• Best For: Close-proximity hookups such as connecting regulator output to a nearby heater.

Choose a short, manufacturer-specified hose assembly like this when your heater sits close to the tank or regulator and when thread compatibility matches appliance requirements.

GasSaf 6 Ft Low Pressure Regulator

The GasSaf product is a CSA-certified low-pressure regulator with a six-foot hose using a QCC1/Type 1 cylinder connection. It’s tailored for grills, patio heaters, and fire pit tables that specify low-pressure input and is listed as compatible with many major grill models.

• Certification: CSA certification supports compliance with recognized safety standards.
• Connection: QCC1/Type 1 cylinder fitting on the tank side, 3/8″ flare on appliance side.
• Capacity: Designed to handle typical low-pressure appliance BTU ranges and deliver stable flow up to manufacturer ratings.
• Use Cases: Ideal for consumer grills, patio heaters, and low-pressure heater applications.

For consumers with appliances that require a QCC1/Type 1 regulator, this option provides a ready replacement with certification and a standard-length hose appropriate for backyard setups.

Buying Guide: How To Choose The Right Propane Heater Line

Selecting the correct propane line for a heater requires attention to pressure type, length, fittings, materials, and safety certifications. Below are key considerations and comparison perspectives to help match a line to your heater.

1. Pressure Type: Low vs High

Many patio heaters and grills operate on low-pressure (around 11″ water column) regulators, while some appliances and portable burners use higher pressure. Confirm your heater’s specification: using a high-pressure hose on a low-pressure appliance can cause improper operation and safety hazards.

2. Regulator Needs

Some hoses include a regulator (single- or two-stage). For portable buddy heaters or appliances that require a specific regulated inlet, choose a hose with the correct regulator type. Two-stage regulators can improve flow stability for variable demand applications.

3. Length And Pressure Drop

Longer hoses increase versatility but can introduce pressure drop. For long runs (20–36 ft), select hoses rated for the appliance pressure and consider hose diameter and PSI rating. Shorter runs reduce the risk of leaks and maintain stable delivery.

4. Fittings And Adapter Compatibility

Thread types vary: 3/8″ flare, 3/8″ NPT, POL, QCC1/Type 1, and pipe threads are common. Check both tank/regulator ends and appliance connections. Kits with multiple adapters increase compatibility, but ensure adapters are properly tightened and sealed with appropriate tape or thread sealant when required.

5. Material And Durability

Stainless braided hoses resist abrasion and animal chewing, while rubber hoses with brass fittings offer flexibility and corrosion resistance. Verify stretch and pressure testing specifications and choose materials suited for outdoor exposure and temperature extremes.

6. Safety Certifications

Look for CSA, UL, or other regional safety certifications when available. Certified hoses and regulators meet independent safety standards and can be important for insurance or code compliance.

7. Application Scenarios

• Backyard Patio Heater: Low-pressure CSA-certified regulator with 6–12 ft hose often sufficient.
• RV Or Slide-Out Connection: High-pressure rated braided hose with proper fittings and camper-specific adapters.
• Fire Pit Or Grill With Remote Tank: Longer high-pressure hoses (20–36 ft) with adapter kits support tank placement away from the appliance.
• Portable Buddy Heaters: Use manufacturer-specified hoses (F273684 equivalents) with two-stage regulators where required.

8. Installation And Leak Testing

Always follow manufacturer instructions. After connections, perform a soap-and-water leak test at all joints. Never use open flame to test for leaks. Ensure hoses do not kink, rub, or sit under strain.

9. Maintenance And Replacement Intervals

Inspect hoses regularly for cracks, abrasions, or corrosion. Replace hoses that show wear or after long periods in harsh environments. Replace regulators that show malfunction signs or after manufacturer-recommended service intervals.

10. Matching Hose To Heater Specification

Compare the heater’s manual for recommended hose length, pressure, and fitting type. When in doubt, choose a hose assembly that matches both the regulator output pressure and physical connection types rather than forcing adapter-only solutions.

Comparison Summary: For long reach needs, consider stainless braided high-pressure hoses with multiple adapters (e.g., 36 ft or 20 ft options). For direct heater connections, manufacturer-style shorter assemblies or regulated hoses (F273684-style or Mr. Heater assemblies) ensure compatibility. For consumer grills and many patio heaters, a CSA-certified low-pressure regulator with a short hose (6–12 ft) is often the appropriate choice.
