DK-LOK DT Union Tee

The DK-LOK DT is a union tee that connects three lines of the same tube outside diameter in a tee configuration, all using gauge-able twin-ferrule tube ends. It is a tube-to-tube fitting offered in 316/316L stainless steel and brass across sizes from 1/16 inch to 2 inch O.D. The base DT code carries no material suffix, so material must be confirmed by the trailing code.
