Kwik Seal is a precisely sized manhole connector made to fit in a cored or cast opening.

The connector is placed into the opening and the pipe is pushed home. This creates a watertight seal when the connector is compressed around the pipe OD and is deformed against the manhole opening. The sealing is similar to how a pipe gasket seals pipe joints.

A simple and effective manhole connector for pipes entering manholes and other underground structures.

Features and Benefits

  • Requires no installation tools, in the plant or in the field
  • Easily replaced if damaged
  • Requires no special tooling for forming holes

How It Works
KWIK SEAL uses simple principles:

  • Specially developed synthetic rubber is continuously tested and lab-certified.
  • The connector is specified based on the difference between pipe OD and hole ID.
  • The gasket is placed into the structure opening.
  • The pipe is beveled and the pipe and connector are lubricated.
  • The pipe is inserted through the connector, compressing it between the concrete and the pipe.
  • Installation is complete

A watertight flexible pipe-to-manhole connector shall be employed in the connection of the sanitary sewer and/or storm water pipe to precast manholes or other structures.

The connector shall be KWIK SEAL as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal.

The connector shall be the sole element relied on to assure a flexible watertight seal of the pipe to the structure. The connector shall consist of a single rubber gasket, shall be constructed solely of synthetic or natural rubber, shall meet/exceed the requirements of ASTM C 923, and shall have a minimum tensile strength of 1600 psi.

Selection of the proper size connector for the manhole and pipe requirement, and installation thereof, shall be in strict conformance with the recommendations of the connector manufacturer. Any dead end pipe stubs installed in connectors shall be restrained from movement per ASTM C 923.

The finished connection shall provide sealing to 13 psi (minimum), and shall accommodate deflection of pipe to 7 degrees (minimum) without loss of seal.
Vacuum testing shall be conducted in strict conformance with ASTM C 1244 prior to backfill. Other testing shall be conducted in strict conformance with the requirements of the connector manufacturer.

TO PREPARE STRUCTURE OPENING FOR GASKET

  • Clean opening thoroughly, removing any dirt or debris.
  • If needed to retain gasket in structure opening, spray TRANSTAR Contact Adhesive (caution – flammable) all around entrance area of opening at least 2-inches (50 mm) wide

TO INSTALL GASKET INTO MANHOLE

  • Install gasket by squeezing into a heart shape and inserting into hole from outside of structure
  • Smooth gasket around hole by working any excess rubber around the hole until gasket lies flat against hole ID
  • Push gasket lip back into hole until it bottoms completely around hole

TO INSTALL PIPE INTO GASKET

  • Make sure that pipe end is clean and well-beveled for at least 3/4’’ (19 mm) from end all around
  • Make sure that pipe end is clean for at least 15” from end
  • Apply lubricant generously to pipe and to fins of installed gasket. Make sure that entire pipe is lubricated for at least 15’’ from end
  • DO NOT APPLY ANY LUBRICANT TO UNDERSIDE OF CONNECTOR
  • Center pipe carefully in gasket and begin to push inward. Push straight into hole. Installation pressure will drop slightly after first fin is cleared. This locks gasket into the hole
  • Continue pushing, and pressure will increase until pipe end clears gasket completely
  • Move pipe inward until it clears interior plane of structure wall
  • Move pipe to proper elevation and angle. Installation is now complete

RCP: Reinforced concrete pipes produced to ASTM C76 specification standards.

*Due to varying hole size circumferences caused by different manhole radius’s and straight wall structures, the structure size and type are required when ordering Kwik Seal for 12” thru 24” reinforced concrete pipe, and 18” thru 24” PVC pipes.

*For concrete pipe, Kwik Seal meets or exceeds ASTM C1478 and the physical properties of ASTM C923 only.
