LETTER 1 filename1.txt August 4, 2006 Via U.S. Mail and Facsimile (713-683-6654) John U. Clarke President and Chairman of the Board NATCO Group Inc. 2950 N. Loop West, 7th Floor Houston, Texas 77092 Re: NATCO Group, Inc. Form 10-K for the Fiscal Year Ended December 31, 2005 Filed March 15, 2006 File No. 1-15603 Dear Mr. Clarke: We have reviewed your response letter dated July 28, 2006 and have the following comment. After reviewing this information, we may raise additional comments. General 1. In your response to prior comment 2, you express the view that your contacts with Iran, Sudan and Syria, countries identified as state sponsors of terrorism, are not qualitatively material to you because the contacts have been made in compliance with U.S. law, and because you have "consistently reported information regarding sales to embargoed countries, if any, in each Form10-K filing since becoming a public company in January 2000." Please expand your materiality analysis to address the possibility that, notwithstanding the legality of your contacts with Iran, Sudan and Syria, your reputation and share value may be negatively impacted by the fact that you do business in these countries that have been identified as terrorist-sponsoring states. In this regard, we call to your attention the investor sentiment evidenced by, among other investor actions, the initiatives cited in our prior comment 2. Please also address the fact that, while the Form 10-K discusses your 2005 contacts with Syria, your earlier reports on Form 10-K do not specifically discuss contacts with Iran, Sudan or Syria, or indicate that the referenced "embargoed countries" included terrorist- sponsoring states. * * * * * Please respond to this comment within 10 business days or tell us when you will provide us with a response. Please file your response letter on EDGAR. Please understand that we may have additional comments after we review your response to our comment. Please contact Pradip Bhaumik, Attorney-Advisor, at (202) 551-3333 if you have any questions about the comments or our review. You may also contact me at (202) 551- 3470. Sincerely, Cecilia D.
