The nozzle insert may include a first radially outer sealing surface sealed against a first inner surface of the nozzle bore via a first seal feature, a second radially outer sealing surface sealed against a second inner surface of the nozzle bore via a second seal feature, and an annular threaded body portion to secure the nozzle insert within the at least one nozzle bore. The downhole system may further include a nozzle pressure chamber formed between the first seal feature, the second seal feature, a radially outer surface of the nozzle insert, and a radially inner surface of the at least one nozzle bore. The pressure chamber is configured to provide a retaining force on the nozzle insert.
