Installation PSI Plugs
1. Check the opening
The inside of the tube, tube or hole must be carefully cleaned.
2. Lubricate
It is recommended to lubricate the inside of the opening as well as the outside and inside of the PSI plug with acid-free petroleum jelly. This simplifies installation and extends the life of the seal. The acid-free vaseline is available from TTT, in 150 ml packs.
3. Assemble
Make sure the pipe or tube is placed exactly in the center of the grommet. Place the two equal parts of the PSI seal, with the flange on the discharge side, around the pipe or tube you want to seal. Push the plug into the opening with both hands. The two parts must be exactly on top of each other to create a good seal. The seal can be inserted until the flange reaches the discharge side. Don't push any further!
When installation becomes more difficult, for example with larger sizes, the seal can be gently hammered in with a flat piece of wood or a hammer.
If you want to seal in a place where pressure can come from both sides, a PSI plug is placed on both sides of the wall to seal both rooms. This method is also necessary for a gas-tight seal.

Different types, different applications
The PSI plug has four application areas: plastic pipes, steel casing pipes (DIN and ASTM) and in pre-drilled holes or aluminum pipes. The sealing system has been tested according to IMO regulations and proven to be fire-retardant, watertight, gas-tight and pressure-tight. MED type approval for fire safety class A60 is also available. Read more about the differences here
