CSST connections can be used with which gas equipment?

CSST connections can be used with which gas equipment?

• A. Not allowed for gas systems
• B. Can be used with both natural and propane gas equipment
• C. Only natural gas equipment
• D. Only propane

Answer: (B)

CSST is flexible piping designed to carry either natural gas or propane to appliances. The tubing and fittings are rated for both gas types, so the system can be designed to supply natural gas or propane equipment as needed. The key is to match the gas type throughout the system (appliances, regulators, and supply) and to follow installation guidelines, including bonding and grounding requirements to protect against electrical surges or lightning. This is why the correct answer is that CSST connections can be used with both natural and propane gas equipment.
