When installing CSST, what should be kept in place to protect the tubing from corrosion?

• A. Keep the protective plastic jacketing in place
• B. Remove the jacket to allow heat dissipation
• C. Paint the jacket with a corrosion-resistant coating
• D. Use a metal conduit around CSST

Answer: (A)

Preserving the outer protective jacket is essential for keeping CSST from corroding. The plastic jacket acts as a barrier against moisture, soil chemicals, and physical wear that can attack the metal over time. When the jacket stays in place, the tubing remains protected in most environments, maintaining the system’s longevity and safety. Removing the jacket to “dissipate heat” isn’t addressing corrosion and leaves the metal exposed; painting the jacket offers no real corrosion protection and can violate listings; wrapping CSST with metal conduit isn’t required and can complicate installation. Keeping the jacket on is the best way to shield the tubing from corrosion.
