PEC Manufacturing – American Made

We Build Everything

PEC Manufacturing is a small family owned company based in Marble Falls, TX. PEC is owned by me and my wife, Penny. Our daughter Kelsey started in 2017 as the Operations Manager with the end goal of taking over as President. PEC was initially started in 1990 to provide replacement parts for the Twin Disc brand PTOs. After a few years in the replacement parts business, it became readily apparent that there was a need for the complete PTO units as well as replacement parts. This is why; in 1993 we started building whole units. It was then that we began to grow our manufacturing abilities with the purchase of our first CNC lathe as well as many other manual machines. We have grown to have several CNC lathes and CNC mills here at our facility where we machine our castings that are sourced from foundries in Alabama and Texas. We take great pride in being the ONLY supplier of Twin Disc style parts that are manufactured in the United States.

Thank You For Your Continued Support –
