Thank you for your question, Ryan. Unfortunately, we dot currently offer a High-Flow (HF) version of the R10000 that comes with PEX fittings. However, you can adapt either the R10000-UNBXHF or R10000-UNWSHF for 1/2" PEX. This should not reduce maximum flow rate from the valve as this is primarily determined by the water pressure in the home.
Best regards, Jon
