A manually installable polymeric plug useful for hydrostatic pressure testing of polymeric pipe or tubing having a flexible wall, the plug having a substantially rigid polymeric handle with a threaded cylindrical section that is engageable with the polymeric pipe or tubing, and an elastomeric sealing member that extends forwardly of the first element and is insertable into the open end of the polymeric pipe or tubing and blocks fluid flow through the interior of the threaded cylindrical section, the elastomeric sealing member having a plurality of axially spaced sealing surfaces that provide a fluid seal between the sealing member and the inside wall of the polymeric pipe or tubing.

Plug for hydrostatic testing of flexible polymeric pipe or tubing

A bend support bracket for flexible polymeric tubing, the bracket being installable inside a wall and having an arcuate guide surface, an oppositely disposed arcuate gripping surface and a flexible attachment arm, the flexible attachment arm having a fixed end that is unitarily molded to the body, a free end that comprises a positioning groove into which a portion of an inwardly facing wall of an aperture in a bracket support strap is receivable, and an outwardly facing, arcuate biasing surface disposed between the first and second ends, wherein the application of manual pressure to the biasing surface biases the positioning groove into alignment with the aperture wall so that a portion of the aperture wall is receivable in the positioning groove.
