The Sterling Group, a middle market private equity firm based in Houston, Texas, today announced that it has entered into a definitive agreement to sell its portfolio company, Velcon Filters, LLC to Parker Hannifin Corporation (NYSE: PH). Terms of the transaction were not disclosed.

Headquartered in Colorado Springs, Colorado, Velcon is a niche manufacturer of filtration systems, including vessels and replacement cartridges, which meet specific requirements for fluid filtration processes in a variety of domestic and international end-markets.

Today, Velcon has a global platform servicing the aviation, industrial and oil and gas filtration markets in over 150 countries. Sterling identified Velcon as a buy-and-build platform and completed three strategic acquisitions in three years. The business more than doubled in size during Sterling’s ownership.

The transaction is expected to close in the fourth quarter of 2012 and is subject to regulatory approval. The Sterling Group was advised by Robert W. Baird & Co. and Willkie Farr & Gallagher.
