PSX:POSITIVE SEAL provides a durable flexible connection between pipes and concrete structures.  In sanitary, stormwater, and other applications, PSX:POSITIVE SEAL is widely specified and accepted for exceptional watertight performance.

Features and Benefits

  •  Installs quickly and easily from outside the manhole.
  • Requires no retightening or adjustment.
  • Single piece stainless-steel power sleeve.
  • No plastic parts to crack or break.
  • Extra-long with double-clamp capability in all sizes.

How It Works

  • Specially developed synthetic rubber is continuously tested and lab-certified to ASTM C 923.
  • Power Sleeve made from heavy-gauge tempered Series 304 stainless steel.
  • Calibrated hydraulic installation tool ensures powerful sealing.
  • Take-up clamps made from Series 304 stainless steel with quick-adjusting screws.

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

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

The connector assembly 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 rubber gasket, an internal expansion sleeve, and one or more external compression take-up clamps. Approved materials for the connector shall be virgin rubber and Series 300 non-magnetic stainless steel. No plastic components shall be permitted.

The rubber gasket element 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. Minimum thickness of the cross-section shall be 0.275 inches (7 mm).

The internal expansion sleeve components shall be made of Series 300 non-magnetic stainless steel and shall utilize no welds in their construction.

Installation shall be performed using a calibrated installation tool available from the connector manufacturer. Installation of the sleeve shall require no retightening after the initial installation.

The external compression take-up clamp(s) shall be constructed of Series 300 non-magnetic stainless steel and shall utilize no welds in its constructions. The clamp(s) shall be installed by torqueing the adjusting screw using a torque-setting wrench available from the connector manufacturer.

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.

  1. Inspect hole. Wall surface must be CLEAN and SMOOTH. Fill all voids with
    non-shrink cementations patching compound and allow to dry.
  2. Place gasket into porthole with holes in stainless steel power sleeve at the 6 o’clock position. Gasket should rest 1/2” to 1” from the inside of the hole.
  3. Place hydraulic tool inside gasket and open slightly by closing valve and pumping the handle on hydraulic unit. Align and insert studs of tool in
    holes of power sleeve. (see illustration A)
  4. Once studs are inserted in power sleeve, pump hydraulic unit until gasket stays positioned in the hole without any hand assistance. Gasket
    must be aligned square in the hole at this point. Make any necessary
    adjustments in sleeve ends to ensure that they are aligned on top of
    each other.
  5. Pump the hydraulic unit to start expanding power sleeve. (see illustration B)
  6. Continue pumping the hydraulic unit while watching sleeve ends to
    make sure they stay aligned on top of each other.
  7. Once the sleeve ends snap into place face-to-face, check the gauge to
    make sure minimum pressure (see above) has been achieved.
  8. Relax the power sleeve slightly by releasing valve on hydraulic pump.
    This will interlock the ends of the power sleeve to ensure a positive seal.
