onlyfire Propane Extension Hose 10ft 5/16" ID — 1/4" NPT Male to 1/4" Female Flared, Brass Fittings for Low-Pressure LP

The onlyfire 10-foot propane extension hose adds safe low-pressure length between your propane tank and appliance using a 5/16" inner-diameter hose with brass ferrules and a 1/4" NPT male to 1/4" Female Flared B connection.

This extension hose is made to give you extra reach and flexibility when the standard regulator hose isn’t long enough. It uses brass fittings and ferrules for corrosion resistance and reliable sealing, and is specifically configured for low-pressure LP systems. Before buying, check that your appliance accepts a 1/4" female flared (ball seat) connection rather than a standard 1/4" female NPT fitting.

How does this hose extend my propane setup safely?

The onlyfire extension provides ten feet of added hose length so you can position grills, fryers, or RV appliances further from the tank. All-metal brass fittings and ferrules reduce the risk of leaks at the connection points when properly tightened and checked.

• 10-foot length gives more placement options for appliances
• 5/16" inner diameter maintains proper low-pressure flow
• Brass fittings and ferrules resist corrosion and form tight seals
• Made for low-pressure propane use only — not for high-pressure cylinders

Will this fit my grill, turkey fryer, or RV appliance?

Compatibility depends on the fitting types on your appliance and regulator: this hose has a fixed 1/4" NPT male on one end and a 1/4" Female Flared B (ball seat swivel) on the other. Many grills, fryers, and portable LP devices use these low-pressure connections, but always match the exact fitting profile before connecting.

• 1/4" NPT male on one end — does not rotate
• 1/4" Female Flared B on the other end — swivel for easier installation
• Designed for low-pressure LP systems like grills, fryers, campers
• Always verify appliance connection type prior to purchase

How should I install and maintain the extension hose?

Installation is straightforward: attach the correct ends to the regulator and appliance, hand-start then tighten fittings with the appropriate tools, and perform a leak check with soapy water or an approved leak detector. Regular inspections for cracks, kinks, or wear will help keep the line safe and functional.

• Hand-thread, then secure fittings with a wrench — avoid over-tightening
• Perform a soap-and-water leak test after installation and periodically
• Replace the hose if you detect cracks, brittleness, or persistent leaks
• Store away from direct heat and sharp edges when not in use

What are the hose’s core specifications and limitations?

This product is a 10-foot, 5/16" inner-diameter hose fitted with all-brass ferrules and connectors for low-pressure propane applications. It is not rated for high-pressure service and is intended only where a 1/4" NPT male to 1/4" Female Flared B hookup is required.

• Total length: 10 feet
• Inner diameter: 5/16"
• Connectors: 1/4" NPT male (fixed) and 1/4" Female Flared B (swivel)
• Material: brass fittings and ferrules; configured for low-pressure LP

Who is this for: The onlyfire 10-foot propane extension hose is aimed at homeowners and outdoor cooks who need extra distance from their propane tank to grills, turkey fryers, camping stoves, or RV appliances. It’s best for users who confirm their appliance accepts a 1/4" Female Flared B connection and want corrosion-resistant brass fittings for reliable low-pressure propane service. If you need a hose for high-pressure cylinders or a different fitting type, choose a product matched to those specifications.
