The Ham-Let Let-Lok bulkhead compression fitting is made of type 316 stainless steel and has tube and NPT male connectors. This bulkhead fitting mounts on a wall or bulkhead to allow tube connections on either side of barrier. It connects to pipes or tubing on one end and an NPT male connector on the other. This fitting is made of type 316 stainless steel for higher strength and greater corrosion resistance than 304 stainless steel. This fitting is suitable for high pressure applications in industrial settings such as petrochemical, fluid, power, and nuclear environments. It meets American Society for Testing and Materials (ASTM) specifications A213 and A269 for quality assurance.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

Ham-Let manufactures instrumentation valves, pipe, and tube fittings. The company, founded in 1950, meets International Organization for Standardization (ISO) standard 9001.
