Good day! Thank you for posting a question about the Kohler K-922-CP Laminar Flow Bath Spout. Sorry, we can't find the information. But if this may help, this laminar bath filler, features a 0.8" (20 mm) orifice to optimize performance with a pressure-compensating flow control to deliver a clear column of water without splatter. You may check this specification sheet and installation guide for more information. We have contacted Kohler and hope to hear from them soon. You may leave your email address below so we can contact you when we receive the answer. If you're interested in purchasing this bath filler, just simply click "Add to Cart" and enter the required information and you'll be all set.
