Gentlemen:

This opinion relates to the registration statement on Form S-4 (the
"Registration Statement") being filed today by Numatics, Incorporated, a
Michigan corporation (the "Issuer"), and certain of its subsidiaries which are
"Guarantors" (as defined in the Registration Statement) with the Securities and
Exchange Commission (the "Commission") for the purpose of registering under the
Securities Act of 1933, as amended (the "Act"): (a) $115,000,000 principal
amount of the Issuer's 9 5/8% Series B Senior Subordinated Notes due 2008 (the
"Exchange Notes"); and (b) the Guarantors' guarantees of the Exchange Notes (the
"Subsidiary Guarantees"). The Exchange Notes are to be issued in exchange for
the Issuer's outstanding 9 5/8% Senior Subordinated Notes due 2008 (the "Notes")
pursuant to the Exchange Offer described in the Registration Statement. As your
counsel, we have examined such certificates, instruments, and documents and
reviewed such questions of law as we have considered necessary or appropriate
for the purposes of this opinion, and, on the basis of such examination and
review, we advise you that, in our opinion:

1.    The Exchange Notes have been duly authorized by all necessary corporate
      action on the part of the Issuer, and the Subsidiary Guarantees have been
      duly authorized by all necessary corporate action on the part of the
      Guarantors.

2.    When the Registration Statement has become effective and the Exchange
      Notes have been issued in exchange for the Notes pursuant to the Exchange
      Offer, the Exchange Notes will be legally issued and will be binding
      obligations of the Issuer, and the Subsidiary Guarantees will be legally
      issued and will be binding obligations of the Guarantors.

 
                 MILLER, CANFIELD, PADDOCK AND STONE, P.L.C.

                                       -2-


We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the prospectus forming a part of the Registration Statement. In
giving this consent, we do not thereby admit that we are within the category of
persons whose consent is required under Section 7 of the Act or the rules and
regulations of the Commission.

Very truly yours,


Miller, Canfield, Paddock and Stone, P.L.C.
