                                SECOND AMENDMENT
                                      TO
                                CREDIT AGREEMENT

     This Second Amendment to Credit Agreement (this "Second Amendment"), 
dated as of June 1, 1995, is among Michigan National Bank, a national 
banking association, and the other banking institutions who appear as 
signatories to this Second Amendment (each a "Bank" and collectively the 
"Banks"), Michigan National Bank, as agent ("Agent"), and Mueller 
Industries, Inc., a Delaware corporation ("Borrower").

                                   Recitals

     The parties hereto executed a certain Credit Agreement (the "Credit 
Agreement") dated as of June 1, 1994, providing for, among other things, 
the establishment by the Banks for the benefit of the Borrower of a line of 
credit in the amount of $30,000,000.  The Credit Agreement was first 
amended by a First Amendment to Credit Agreement, dated as of December 14, 
1994 (the Credit Agreement, as so amended, the "Amended Credit Agreement").

     The Borrower has now requested the Banks to consider certain 
amendments to the Amended Credit Agreement and the Banks have consented to 
such amendments as set forth herein upon the terms and conditions set forth 
herein.

     Capitalized terms used but not defined herein shall have the meanings 
ascribed to them in the Amended Credit Agreement.

     NOW, THEREFORE, the parties hereto agree that the Amended Credit 
Agreement shall be amended, effective (unless otherwise specified herein) 
on and as of June 1, 1995, as follows:

     1.  The definition of the term "Brass Guaranties" in Section 1, on

parenthetical clause "(other than Streamline Copper & Brass Ltd.)".

     2.  The first line and first clause of the definition of the term 
"Line of Credit Maturity" (which ends with the date "June 30, 1996") in 
Section 1, on page 7, shall be revised in its entirety to read as follows:

"Line of Credit Maturity" means June 30, 1997;

     3.  Section 2.1, on page 11, shall be revised by substituting for the 
amount "$30,000,000" at the beginning of the sixth line thereof the amount

     5.  Section 2.4, on page 13, shall be revised by substituting for the

     6.  Section 3.6.7(a), on page 20, shall be revised by substituting for 
the term "one percent (1%)" in the sixteenth line thereof the term "eight-

     7.  Section 4.3, on page 23, shall be revised by adding to the end of 
the first sentence thereof on the fifth line thereof, immediately preceding 
the period and following the word "Borrower", the parenthetical clause 
"(except, for purposes of this Section 4.3 only, with respect to those 
Subsidiaries listed on Schedule 1.1 hereof in which Borrower is shown as 
owning less than 100% of the capital stock, the direct or indirect 
percentage ownership of Borrower may be more than as shown on Schedule 
1.1)".

     8.  Section 5.3.1, on pages 26 and 27, shall be revised in its 
entirety to read as follows:

     5.3.1  As soon as available and in any event within forty-five (45) 
days after the end of each fiscal quarter of Borrower, management prepared 
consolidated and consolidating financial statements of Borrower and 
Subsidiaries as of the end of such quarter, and the consolidated and 
consolidating statements of profit and loss and surplus of Borrower and 
Subsidiaries from the beginning of Borrower's and Subsidiaries' fiscal year 
to the end of such quarter, certified as correct (subject to year end 
adjustments) by the chief financial officer of Borrower.

     9.  The signature pages of the Amended Credit Agreement shall be 
revised to reflect the addition of Boatmen's First National Bank of Kansas 
City and Mercantile Bank of Kansas City as Bank parties to the Amended 
Credit Agreement and the ratable shares and commitments of all Banks,

this Second Amendment.  The Borrower shall execute new Notes and shall 
cause the Brass Subsidiaries to execute new or amended Brass Guaranties 
which conform to the provisions of this Second Amendment, such execution 
(and delivery of such Notes and Brass Guaranties to the Agent) being a 
condition to the effectiveness of this Second Amendment.

     11.  Except as herein provided, the Amended Credit Agreement shall 
remain in full force and effect, including the provisions of Section 9 
thereof which are herein incorporated by this reference.



    3
     12.  The Borrower hereby affirms the representations and warranties 
set forth in Section 4 of the Amended Credit Agreement and certifies that 
no Event of Default has occurred or is existing under the Amended Credit 
Agreement.

          IN WITNESS WHEREOF, the parties hereto have caused this Second 
Amendment to be executed and delivered as of the date first hereinabove set 
forth.
