ABSTRACT:
A pneumatic test plug for clean-out tees having an elastomeric inflatable body, a closed top, an inwardly tapered side wall and an open bottom end with a peripheral shoulder having a downwardly extending peripheral ridge. A molded end cap with a cylindrical wall having exteriorly disposed threads and an inwardly disposed circular retention channel or area receives a retention collar for placement within the molded end cap and between the cylindrical wall and the inflatable body bottom end. The retention collar fixes the peripheral shoulder and downwardly extending peripheral ridge in the circular retention channel or area of the end cap and compressingly holds the peripheral shoulder of the inflatable body into the end cap.
