Chokes
Invented by MSI in the mid 1980’s, the MSI choke is designed to safely control the flow while remaining compact and lightweight. Whether it’s an adjustable or positive, STD service or H2S, ¾” orifice or 2” max, hydraulic or manual, as part of a complete manifold or installed on a sand trap, the MSI choke line is manufactured to assist with your flow control needs.
