Apply to the Oklahoma Construction Industries Board (CIB) — Plumbing Division, verify your Pennsylvania license, and meet Oklahoma's endorsement requirements. Oklahoma waives its journeyman plumbing exam only for applicants who hold an unlimited plumbing journeyman (or higher) Arkansas license obtained by Arkansas examination and held at least one year in good standing, under the Oklahoma-Arkansas reciprocity agreement effective 2024-10-21; all other out-of-state plumbers must qualify with three years of experience (or an approved education substitution) and pass the Oklahoma journeyman exam.

Verdict
Licensure by endorsement
Pennsylvania is not among the states Oklahoma names for an automatic exam waiver, so this move runs on the Oklahoma Construction Industries Board (CIB) — Plumbing Division's individual endorsement or equivalency review rather than a guarantee. Oklahoma waives its journeyman plumbing exam only for applicants who hold an unlimited plumbing journeyman (or higher) Arkansas license obtained by Arkansas examination and held at least one year in good standing, under the Oklahoma-Arkansas reciprocity agreement effective 2024-10-21; all other out-of-state plumbers must qualify with three years of experience (or an approved education substitution) and pass the Oklahoma journeyman exam. Bring your Pennsylvania license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
