A-Lok - Model G3 -Watertight Seal Boot System

SHARE

The revolutionary G3 BOOT SYSTEM makes installation into a structure simple and fast. Just install the connector perpendicular to the hole and tighten the stainless steel nut. As the nut is tightened, a compressive force is applied to the G3 band ends, causing the ends to slide past each other into straight alignment. This movement increases the bands overall circumference and compresses the connector against the opening in the structure wall, creating a watertight seal. To ensure the best seal, place the bolt in the 12 o’clock position of the hole opening and tighten the nut to the specified torque value.

The G3 BOOT SYSTEM is manufactured to meet or exceed all material and test requirements set forth in ASTM C-923, ASTM C-1478 and ASTM F-2510.

  • Can withstand 15° of omnidirectional deflection and ½” of centerline offset while still maintaining a watertight connection which eliminates infiltration due to pipe shear caused by settlement or ground movement
  • The inner O-ring design of the G3 BAND eliminates rubber wrinkling which compensates for pipe irregularity and wall thickness to insure a watertight seal
  • The G3 COMPONENT PACKAGING features a tough loop lock fastener that keeps installation instructions, takedown clamp, boot and band secure together from factory to job site

A flexible pipe to manhole connector shall be used whenever a pipe pentrates into a precast concrete manhole or structure. The connector shall be the G3 Boot System featuring component packaging as manufactured by A-LOK Products, Inc., Tullytown, PA or approved equal.

The design of the connector shall provide a flexible, watertight seal between the pipe and concrete structure. The connector shall assure that a seal is made between (1) the connector and the structure wall by placing the connector and expansion band into the center third of the concrete hole opening. The band is then expanded by tightening the expansion mechanism increasing the bands overall circumference and compressing the connector against he sides of the hole opening. (2) The seal between the connector and the pipe shall be made by compressing the connector against the outside circumference of the pipe by means of a stainless steel take-down band.
