The deal, which is the biggest in the history of the Youth Academy, will see the club's NIBFA National League teams at Under 16, 15, 14, 13 and 12 age groups all wear new Uhlsport kits with the Tullyglass logo on the front.
Youth Academy secretary and coach Davy Douglas said; "We are extremely proud and honoured to have such a prestigious sponsor for our Academy. "
"Gus McConville and Tullyglass have been very supportive of our Academy over the past four years and this deal will allow us an opportunity to further enhance the partnership that has been established".
Chairman John Anderson also thanked Tullyglass; "Gus has taken a keen interest in the Academy and has sponsored Davy Douglas' team over the past few seasons. We are delighted to extend this partnership to cover all our National League teams."
"This sponsorship is the largest in the history of the Youth Academy and we are extremely grateful for the continued support. I would also encourage all connected with the Youth Academy to support our main sponsor".
The kit was launched at Tullyglass Hotel with players from each NIBFA National League team in attendance and supported by Ballymena United senior team assistant manager Bryan McLoughlin.
