ABSTRACT:
A pipe fitting having a end flange and forming a port radially inwardly of the flange to align with the wall opening; an annular elastomeric seal positioned to be compressed between the flange and the work body wall for preventing leakage of fluid outwardly from the wall opening; a test cap unit spaced from the seal and aligned therewith to close off the opening and fastener structure extending through the cap unit and adjustably attached to the fitting for urging the cap unit into sealing relation with the inner side of the work body wall, about the opening, when the seal is compressed as aforesaid, whereby the cap unit then closes off the opening so that test liquid under pressure can be filled into the fitting to test for leakage adjacent the elastomeric seal.
