The Ham-Let 316 stainless steel Let-Lok compression fitting is made of stainless steel and connects to tubing and Society of Automotive Engineers (SAE) connectors. This adapter connects pipes or fittings with different end types, diameters, or materials. It connects to pipes or tubing on one end and an SAE connector on the other. This fitting is made of 316 stainless steel for higher strength and greater corrosion resistance than 304 stainless steel. The operating temperatures range from 100 to 1000 degrees F. It meets American Society for Testing and Materials (ASTM) standards A213 and A269 for quality assurance. It is suitable for high-pressure applications in industrial settings such as petrochemical, fluid, power, and nuclear environments.

Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. 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 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.
