A valve can pass a hydrostatic test and still leak gas. API 6A PSL 3G adds defined gas testing for wellhead and Christmas tree equipment where that gap matters. This guide covers when to specify it, how to write the service data, what the gas-test records must show, and how to build an auditable RFQ.

API 6A product specification levels set how much material control, traceability, examination, testing, and documentation a wellhead or Christmas-tree component must carry. This guide shows buyers how to compare PSL 1, PSL 2, PSL 3, and PSL 3G, what evidence to request, and how to keep PSL separate from pressure rating, material class, and performance validation.
