Item 5.05 Amendments to the Registrant's Code of Ethics, or Waiver of a Provision of the Code of Ethics.

(a) On October 28, 2009, the Board of Directors of Parker-Hannifin Corporation (the "Company") adopted a Code of Conduct for the Company, which applies to all directors, officers and employees of the Company and supersedes and replaces the Company's Code of Ethics in its entirety.

Х Additional responsibilities of Managers;

Х Bullying and violence;

Х Substance abuse;

Х Import compliance;

Х Dealing with Governments;

Х Political Action Committee;

(b) None of the amendments constitute a waiver of any provision of the Code of Conduct on behalf of the Company's Chief Executive Officer, Chief Financial Officer, or Controller.

The foregoing summary of the amendments to the Code of Conduct is subject to and qualified in its entirety by reference to the full text of the Code of Conduct, as amended and restated, a copy of which is attached hereto as Exhibit 14.1 and incorporated herein by reference.
