Marco Adds Product Depth with Acquisition of Colonial Seal Company

CLEVELAND and DALLAS, June 3, 2025  |  Align Capital Partners’ (“ACP”) custom sealing solutions provider Marco Rubber & Plastics (“Marco” or the “Company”) adds oil seals to its growing product portfolio through its acquisition of Colonial Seal Company (“Colonial”).

Colonial is a specialty distributor of oil seals, O-rings, gaskets and shaft seals for a diverse set of customers operating in pharmaceutical, industrial and other end markets across the United States. This acquisition provides Marco enhanced product breadth and new product lines, unlocking cross-sell opportunities for the Company’s customer base. Colonial also augments Marco’s supply chain with new vendor relationships in highly strategic geographies.

“I am thrilled for Colonial to partner with a market leader in Marco and look forward to working with the team to ensure continued success of the combined business in the years to come. Together, we will remain focused on delivering high quality products and customer service as we pursue new strategic growth opportunities,” said Stephen Maloney, Founder and President of Colonial.

“Under Steve’s leadership, Colonial has earned a fantastic reputation as a reliable source of specialty elastomeric parts and sealing solutions,” said Marco CEO, Marty Daley. “Colonial’s diverse supply chain and product expertise enhance our ability to provide best in class products and value-added services to our entire customer base. I look forward to working with Steve and welcome the Colonial team and customers to Marco.”

ACP acquired a majority stake in Marco Rubber & Plastics in February 2020 and has since completed seven strategic add-ons. Marco will continue to pursue strategic acquisitions to augment the Company’s current product offering and geographic reach. Chris Jones, Matt Bowen, Brad Mundt and Ben Bryles worked alongside Marco management on the transaction.
