Can I Use Compression Fittings on Propane Lines?

Safety Risks

Compression fittings are suitable for low-pressure applications like water or air lines, but propane lines operate at high pressures (typically between 10 and 14 psi) and temperatures. Using compression fittings on propane lines increases the risk of leaks, which can lead to safety hazards, equipment damage, and costly repairs. Even a small leak can cause a propane buildup that may lead to explosion or fire.

Code Compliance

Most local and national building codes, such as the International Fuel Gas Code (IFGC), and the National Fire Protection Association (NFPA) standards, prohibit the use of compression fittings on propane lines. These codes require the use of threaded or flare connections for propane lines, which are designed to handle high pressures and provide a secure seal. Failure to comply with these codes can result in fines, penalties, and even lawsuits.

Alternative Solutions

If you need to connect propane lines, consider using threaded or flare connections, which are specifically designed for high-pressure applications. These connections provide a secure seal and ensure safe operation of your propane system. Always follow the manufacturer’s instructions and local building codes when installing propane lines and connections.
