When to Replace

• After any propane leak is detected at the hose or its fittings.
• If fittings are corroded, damaged, or will not seal properly.
• As part of routine maintenance, typically every 5 to 7 years, depending on use and exposure to elements.

Installation Tips

• Ensure the propane cylinder valve is fully closed before installation or removal.
• Hand-tighten the green or black Acme nut onto the propane cylinder valve. Do not use tools.
• Use a wrench to secure the 1/4" inverted flare fitting to the regulator inlet port. Use a second wrench to hold the regulator fitting to prevent damage.
• After installation is complete, slowly open the cylinder valve and check all connections for leaks using a soap and water solution.
• Position the hose to prevent sharp bends, kinks, and contact with hot surfaces or sharp edges.
