NQN 12ft Stainless Steel Braided Propane Hose Extension with 5 Brass Conversion Couplings — 350 PSI, CSA-Certified

NQN's upgraded 12-foot stainless steel braided propane hose is a high-pressure extension kit with five brass conversion couplings, engineered to link grills, fire pits, heaters and RV appliances to a propane source safely and flexibly.

This kit combines a 12-foot, 350 PSI rated, stainless steel braided 3/8" female flare hose with five solid-brass adapter fittings so you can convert between common flare and NPT connections on the fly. The hose and fittings are CSA-certified and built for durability, corrosion resistance and repeated use in outdoor settings. It arrives ready to install with sealing tape and Velcro straps for tidy mounting or storage.

How does the NQN hose make setting up outdoor gas appliances easier?

The long braided hose gives you room to position grills, fire pits and portable heaters farther from the tank while preserving full-pressure flow. The included conversion couplings remove guesswork — you can adapt the 3/8" female flare ends to several NPT and flare male sizes commonly found on appliances and regulators.

• 12-foot reach for flexible equipment placement
• Five adapter fittings: 3/8" NPT male x 3/8" NPT male; 3/8" flare male x 3/8" flare male; 3/8" NPT male x 3/8" flare male; 1/2" female NPT x 3/8" flare male; 1/4" NPT male x 3/8" flare male
• Includes sealing tape and Velcro straps for a neat install

Is this hose safe and durable for repeated outdoor use?

NQN specifies a 350 PSI working pressure and uses stainless steel braid over the hose for abrasion and weather resistance, while the adapter fittings are machined from solid brass to resist corrosion. The product carries CSA certification for airtightness and stability, reflecting manufacturing and testing standards relevant to propane connections.
