CMP 4-1/8" FD Spa Jet Internal [Dir Smth Scal] [Gray] (23540-111-000) airbuttons The dual-pump plus light formatThe CMP spa jet internal is designed for compatible spa jet applications where a 4 1 8 inch face diameter directional internal needs replacement. A jet internal is useful because it shapes how water moves through the jet face, supporting the intended directional massage action and overall spa jet performance. This replacement is especially useful when the original internal is cracked, worn, clogged, or no longer rotating or directing flow correctly.
