Seal design & function
Trelleborg 911 Multi Connector is a combination of an elastomeric sealing element and a plastic support ring which gives various connection possibilities on the construction site.
The hole 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.
Trelleborg 911 Multi Connector meets the requirements of all current relevant European standards.

Dimensions & Designation
On each seal, profile, diameter and appropriate pipe dimensions together with date of manufacture is given. The corresponding information is also included on the packaging.
Subject to change for technical reasons.
Lubricate the drilled or prefabricated hole using Trelleborg 992 Lube.
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 the most 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 Trelleborg 992 Lube 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.
