| Particularly soft rubber, especially suitable for plastic pipes. Use in normal atmosphere, water or humidity. Suitable for electrical isolation and cathodic corrosion protection. |
| Material type | EPDM-Rubber |
| Bolts | galvanized |
| Shore hardness | Shore A 40° ±5 |
| Pressure plates | glass fibre reinforced polyamide |
| Color | blue |
| UV-resistant | Yes |
| Temperature range | -40 °C bis + 80 °C |
| Pressure-tight | 3 bar |
| Electrical isolation | at Dielectric strength from 500V/mm |
| Max. Tightening torque | 2 Nm |
| The surface of the core drilled holes should be coated to protect the reinforcement from corrosion. Therefore we recommend ProteX epoxy resin or ProteX sealant. The specified values for the pressure tightness are valid at 23 °C. For different, higher permanent operating temperatures, changing temperatures and permanent pressure, it might be necessary to fit an ejection safety device. Please be sure to ask us in advance about the technical feasibility of planned applications for which there is no description (e.g. applications in the biogas or food sector). |

Features
Easy and quick installation due to pre-assembled modules High quality rubber parts ensure long lifetime Protected position in the masonry Suitable for retrofitting Choice of galvanized 8.8 or stainless steel bolts A4-70 Electrically isolating Hydrostatic sealing against pressing waterAreas of application
For sealing wall penetrations of gas, Water, sewage pipes and cables (considering the calculation basis and the suitability of the product on site) Tank embeddings Casing pipe sealsDescription
The radial expansion of the rubber parts ensures a permanent, pressure-tight and secure sealing of the annular space. For particularly thin-walled plastic pipes such as pre-insulated, flexible casing and corrugated pipe systems, a Compakt Temp or Compakt Super Soft is recommended.
The suitable LINK-SEAL® for the application results from the thickness of the annular space between the casing pipe (wall sleeve) and carrier pipe. The perfect LINK-SEAL® is smaller than the annular space in a non-tensioned condition and larger in tensioned- condition.
To calculate the appropriate LINK-SEAL® annular space seal, use our online calculation program or the type selection as a basis for calculation. This is available for you to download online as a PDF
Assembly Instructions
| 1 | Center the pipe, cable or conduit in wall opening or casing. Carrier pipes must be suitable, dimensionally stable and without damage in the sealing area. Make sure the pipe is adequately supported on both ends. The LINK-SEAL® can only perform a sealing function and does not serve as a pipe support or fixed point. All building and pipeline guidelines are to be observed |
| 2 | Use only in suitable wall sleeves, installation tolerances according to dimensions in the calculation program. The specified clamping ranges must be observed here. This also applies to the dimensions of the carrier pipes. With suitable sealing surface in the inner wall and suitable rigidity (dimensional stability after installation) of the wall sleeve. Loosen rear pressure plate with nutjust enough so links move freelytowards and away from each other connect both ends of belt. |
| 3 | Check to be sure bolt heads are facingthe installer. Extra slack or sag is normal. Do not remove links if extra slack exists. Note: On smaller diameter pipes, linksmay need to be stretched. |
| 5 | Slide belt assembly into annular space. For larger size belts, start inserting LINK-SEAL® modular seal assembly at the 6 o’clock position and work both sides up toward the 12 o’clock position in the annular space. Do not tighten any bolt more than 4 turns at a time. Continue in a clockwise manner. Make 2 or 3 more passes at 3 turns per bolt until links have been uniformly compressed and the max. torque moment (see table) is reached. |
| 6 | Repeat tightening after approx. 2 hours. Especially for LINK-SEAL®Type LS 500 up to LS 700 it might be necessary (depending on the installation conditions such as annular space, temperature, etc.) to tighten again for several times. |
What to do
- Check that the sealing elements, the pipe surface and the inner wall of the core drill or wall sleeve are free of dirt and other contaminants.
- Make sure that the pipe is centered.
- Install the chain and ensure that the pressure plates are evenly aligned.
- install the exact number of segments specified.
- make sure the pipe is properly supported when backfilling.
What needs to be taken into account?
The PSI warranty is limited to the replacement of defective material.
The suitability of the product for the specific use must be checked by the user on his own responsibility. use.
What they are not allowed to do
- Do not install the chain until the pressure plates are aligned.
- Do not install LINK-SEAL® annular space seals on spiral pipes.
- Do not tighten one bolt before moving on to the next.
- do not use a cordless, impact or drill screwdriver.
- note that the LINK-SEAL® is not a fixed point.
Note on installation
We expressly draw your attention to the fact that the installation must be carried out by an authorized specialist company in accordance with the installation instructions.
Tools
Cleaning material/preparation, measuring tool, torque wrench, aids for markings
Recommendation
To create a suitable sealing surface, we recommend coating the core holes with PSI KB epoxy resin. This serves to protect the concrete and to smooth out any shrinkage holes/scoring.
