Milton 1817BK G‑Style male plug 1/2 NPT – high-flow steel plug rated to 300 psi and 99 SCFM, designed for industrial air use with G‑Style compatibility.
Milton 1817BK G‑Style male plug 1/2 NPT is a robust pneumatic plug engineered for demanding industrial and automotive airflow systems. Built with case-hardened steel and corrosion-resistant plating, this fitting ensures reliable performance even in heavy-use shop environments. It is part of Milton’s executive-grade G‑Style series, featuring a substantial 1/2″ nominal flow body and a maximum pressure capacity of 300 psi, while delivering up to 99 SCFM of airflow—ideal for applications requiring flows above 60 SCFM.
These male G‑Style plugs are designed with a 1/2 NPT thread, compatible with both couplers and pneumatic ports. The variation “BK” in the part number indicates steel-plated rust protection. Despite the two available tip configurations (.125 and .375 profile), they are functionally identical in preventing airflow loss or fitting mismatches.
