Apparatus for locating leaks in a heat exchanger of a type having a plurality of tubular elements supported at one end by a fixed tube sheet and at the other end by a floating tube sheet, contained within an elongated cylindrical housing with the housing having flanges for attachment thereto by end vessels. The apparatus includes an elastomeric sleeve couplable, after removal of the end vessels, to a flange of the housing adjacent the floating tube sheet, with provision being made for affixing the sleeve in sealed contact with the flange and also for sealing the elastomeric sleeve to the floating tube sheet. With the apparatus in place the chamber surrounding the tubular elements and between the tube sheets is pressurized with fluid and the ends of each tube and tube sheet inspected at the same time for fluid leaks.
