Can be used with both prefabricated and core drilled holes
Excellent angular deflection performance
Accommodates wide range of pipe diameters
Trelleborg's F-911 is a combined variant of elastomers and plastic support rings, which allows for simplification of various connection possibilities on the construction site.
The hole required can be either prefabricated or drilled with a core bit. The external ribs (1) are forced against the inside of the hole when the seal is inserted into it.
The plastic support ring (2) should be tapped into place with a rubber or plastic mallet.
The pipe that is to be connected to the manhole is inserted through the coupling (3), which has three or four collars, for different sizes of pipe.
If a larger pipe is to be inserted then the surplus, smaller section of the coupling is cut away using the appropriate recess (5).
The coupling is sealed to the pipe by means of a stainless steel clamping band (4).
The clamping band that is supplied with the coupling will fit all the pipe sizes that the connector is designed for.
F-911 meets the requirements of all current relevant European standards.
Flexible connection system for pipes to manholes and for passing pipes through concrete walls and structures
100 % leak-free
Examples of Sizes (mm)
Data in mm.
On each seal, profile thickness, outer diameter, recommended pipe measurement and production period are given. The corresponding data are also on the packaging.

Lubricate the drilled or prefabricated hole using F-992 Lub.
Place the seal in the hole and tap it into the correct position using a rubber or plastic mallet. Tap the end of the short plastic supporting ring that is fitted in the seal.
Decide which size collar is appropriate for the connecting pipe. Cut away the surplus part of the coupling using a knife. A special recess is provided for this purpose.
Lubricate with a thin coat of F-992 Lub over the rubber part. Connect the pipe and fit the clamping band in place.
Tighten the screw so that the rubber is compressed against the connecting pipe.
