What to check before ordering

Check length, end configuration and the applicable pressure-temperature and service ratings.
Use approved joint preparation, followed by the required checks by qualified gas personnel.

Service reminder: Pipe schedule and fitting class describe different characteristics. Neither is a stand-alone pressure rating for an entire gas system.
