Proper support for 1/2'' O.D tubing is ____ intervals

Proper support for 1/2'' O.D tubing is ____ intervals

• A. 2 feet
• B. 6 feet
• C. 4 feet
• D. 8 feet

Answer: (C)

The main idea is to keep gas tubing securely supported so it can’t sag or move at the fittings. For 1/2" O.D. tubing, the recommended practice is to place supports every four feet along horizontal runs. This spacing helps prevent stress on joints from gravity, temperature changes, or vibrations, which reduces the risk of leaks or damage. You’d typically also secure the line near connections and at the ends of runs, but four feet is the standard interval for this size. The other intervals would either crowd supports unnecessarily or allow too much movement between supports.
