Re:  Airgas, Inc. 9.125% Senior Subordinated Notes Due 2011

Ladies and Gentlemen:

We have acted as special Texas counsel to Airgas Speciality Gases, Inc., a Texas
corporation (the "Texas Guarantor"), solely for the purpose of rendering this
opinion in connection with the proposed issuance by Airgas, Inc. (the "Company")
of its 9.125% Senior Subordinated Notes Due 2011 (the "Notes") pursuant to the
Indenture dated as of July 30, 2001 (the "Indenture") among the Company, the
subsidiary guarantors listed on Schedule I to the Indenture and The Bank of New
York, as trustee.

In our capacity as such counsel, we have been provided with copies identified as
being true copies of, and have examined, only the following:

     1.   The Unanimous Written Consent of the Board of Directors of the Texas
          Guarantor dated July 27, 2001 (the "Board Consent").

     2.   The Articles of Incorporation of the Texas Guarantor filed with the
          Secretary of State of the State of Texas on January 27, 1986, a
          Certificate of Amendment filed in the Office of the Secretary of State
          of the State of Texas on July 31, 1989 and a Certificate of Amendment
          filed in the Office of the Secretary of State of the State of Texas on
          October 7, 1996 (collectively, the "Articles of Incorporation").

     3.   The Bylaws of the Texas Guarantor adopted on February 18, 1986 (the
          "Bylaws").

     4.   The signature page of the Indenture showing execution by the Texas
          Guarantor as a subsidiary guarantor listed on Schedule I to the
          Indenture.

In addition, we have examined and relied upon a Certificate of Existence of the
Texas Guarantor dated September 4, 2001 issued by the Secretary of State of the
State of Texas and a Certificate of Account Status dated September 4, 2001
issued by the

     c.   The copies examined by us of the Board Consent, Articles of
          Incorporation and Bylaws are true and complete copies of the originals
          thereof, are in full force and effect, and have not been further
