Brass fittings clear a Gulf project on alloy, thread and paperwork — not price. Which conformity scheme each state runs, the G/R/Rp/NPT thread codes, and what DR brass really requires.

Pink fittings, white deposits and threads that shear at normal torque point to one cause. What dezincification is, which water triggers it, and how to specify against it.

Every PPR system meets a metal thread somewhere. How the brass insert is anchored in the plastic body, the variants to stock, thread and alloy specification, and four ways they fail.

A compression joint seals on one thing: an olive deformed against a pipe of exactly the right outside diameter. Size and thread table, insert selection, and why joints weep.

CW617N to EN 12165 or HPb57-3 to GB/T 5231? Compared on lead content, dezincification and market access, with the BSPP, BSPT, G, R and NPT thread codes to put on the order.

Full bore or reduced bore, CW617N or HPb57-3, G / R / Rp / NPT threads, blow-out proof stems — the brass ball valve variables that change the part, with the designations to write on the order.
