According to safety regulations, what type of flare fittings should be used in gas tubing systems?

Any type of flare fittings
Only forged flare fittings
Metal flare fittings
Plastic flare fittings

The correct answer is: Only forged flare fittings

The correct choice emphasizes the use of forged flare fittings in gas tubing systems due to their superior strength and leak-resistant properties. Forged fittings are manufactured from solid metal, which enhances their durability and ability to withstand high pressures typically found in gas systems. This characteristic is vital for ensuring safety and maintaining the integrity of gas lines. Using only forged flare fittings helps prevent leaks, which can pose significant safety hazards, including fire risks and exposure to dangerous gases. In contrast, options that suggest the use of any type of flare fittings, metal fittings without specifying the type, or plastic fittings do not meet the stringent safety and reliability requirements essential for gas installations. Plastic fittings, for instance, are unsuitable for gas applications due to their lower resistance to pressure and temperature fluctuations compared to metal fittings. The regulations prioritize using materials that provide the highest safety standards in gas applications, making forged fittings the appropriate choice.
