Re: Prospectus Supplement for up to $2,700,000,000 Medium-Term Notes, Series A

Ladies and Gentlemen:

We have acted as special tax counsel to Parker-Hannifin Corporation, an Ohio corporation (the “Company”) in connection with the offering of up to $2,700,000,000 aggregate principal amount of the Company’s Medium-Term Notes, Series A (the “Notes”) from time to time on a delayed or continuous basis, as set forth in the Company’s Prospectus (the “Prospectus”), dated February 19, 2013, and the Company’s Prospectus Supplement (the “Prospectus Supplement”), dated November 18, 2014, and as may be set forth from time to time in one or more pricing supplements to the Prospectus Supplement.

You have requested our opinion as to the matters set forth in the discussion under the caption “Certain U.S. Federal Income Tax Considerations” in the Prospectus Supplement. In connection with our opinion, we have reviewed and are relying upon the Registration Statement on Form S-3 (Registration No. 333-186741) of which the Prospectus and Prospectus Supplement are a part (the “Registration Statement”), including the exhibits thereto, the representations contained in a letter dated today addressed to us from the Company, and such other documents, records and instruments as we have deemed necessary or appropriate for purposes of this opinion. For purposes of our review, we have assumed with your consent, the authenticity of all documents we have examined, as well as the genuineness of signatures and the validity of the indicated capacity of each party executing a document.

This opinion is based upon current provisions of the Internal Revenue Code of 1986, as amended, current Treasury regulations issued thereunder, current published administrative rulings and procedures of the Internal Revenue Service, and judicial decisions published to date, all of which are subject to change or differing interpretation, possibly with retroactive effect.

Based upon and subject to the foregoing and subject to the limitations set forth herein, the discussion in the Prospectus Supplement under the heading “Certain U.S. Federal Income Tax Considerations,” to the extent that it describes provisions of federal income tax law, represents our opinion as to the material federal income tax considerations of the matters discussed therein, as of the date hereof.

We do not undertake to advise you of the effect of changes in matters of laws occurring subsequent to the date hereof.

We hereby consent to the filing of this opinion as Exhibit 8.1 to the Registration Statement.
