Thank you for your question, Meg90! Any new BT13010-SS valve trim is going to include an RP46074 cartridge, rather than an RP19804. The RP19804 cartridge is no longer included, with 13/14 series valve trims. An RP19804 cartridge can be used with this valve trim, but would need to be purchased separately.
Best Regards, Benjamin
