The 20-year-old centre-forward has previously enjoyed spells at Lye Town, Studley and Bromsgrove Sporting.
On the signing, manager Simon Hollyhead said: "We're delighted to be able to bring Tyler in at this stage of the season. My thanks go to Matty Taylor and Stephen Ward at Solihull Moors, we're grateful for their assistance in helping us to get this loan sorted and over the line so quickly."
Bruck is available for selection in today's squad as we face Stratford Town at the Spencer Stadium, powered by egg.
Welcome to the Puritans, Tyler!
