LIMITED POWER OF ATTORNEY
(ATTORNEY-IN-FACT TO
EXECUTE SEC FORMS 3, 4 & 5 and 144 FILINGS)

I, Thomas P. Mason, do hereby appoint each William Jason Healy, and Peggy J.
Harrison, signing singly, as my true and lawful attorney-in-fact to:

1.	Execute the following items (each a "report" and, collectively, "reports"),
on my behalf and in my capacity as it relates to my beneficial ownership of
securities of PennTex Midstream Partners, LP or any of its subsidiaries
("Partnership"), and to submit the same to the U.S. Securities and Exchange
Commission (the "SEC"):
a.	Forms 3, 4 and 5 (including amendments thereto) and any other reports
required pursuant to Section 16(a) of the Securities Exchange Act of 1934, as
amended, and the rules thereunder; and
b.	Form 144 and any other similar reports required under the Securities Act of
1933, as amended; and

2.	Perform any and all acts on my behalf which may be necessary or desirable to
complete and execute any Reports and timely file such Reports with the United
States Securities and Exchange Commission and/or any stock exchange or similar
authority; and

3.	Take any other action in connection with the foregoing which, in the opinion
of such attorney-in-fact, may be of benefit to, in the best interest of, or
legally required by the undersigned, it being understood that any document
executed by such attorney-in-fact on my behalf pursuant to this Power of
Attorney shall be in such form and shall contain such terms and conditions as
such attorney-in-fact may approve in their discretion.

I grant to each such attorneys-in-fact full power and authority to do and
perform any act necessary or proper to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes as I
might or could do if personally present, with full power of substitution or
revocation.  I ratify and confirm all that such attorney-in-fact, or any
substitute of such attorney-in-fact, shall lawfully do or cause to be done by
the rights and powers granted by this Power of Attorney.

I acknowledge that each such attorney-in-fact, in serving in such capacity at my
request, is not assuming, nor is the Partnership, assuming, any of my
responsibilities to comply with Section 16 of the Securities Exchange Act of
1934, Rule 144 under the Securities Act of 1933, or applicable federal or state
securities laws generally.

This Power of Attorney shall remain in full force and effect until I am no
longer required to file any Reports with respect to my holdings of and
transactions in securities issued by the Partnership, unless I earlier revoke it
in a signed writing delivered to the General Counsel and Secretary of the
Company.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed this 8th day of November, 2016.
