Pipe Penetration Seals
Waterseal
The Pipeseal Waterseal provides an economincal and sure method of sealing pipes and conduit through walls and floors for 20 psig. Choice first starts with materials. Three types of rubber, and two types of metal hardware are available. For most applications, EPDM is the proper choice, but Nitrile is best if the seal may be exposed to hydrocarbons. Stainless steel hardware can also be used in areas where corrosion is a tougher problem. And Silicone is the choice for high temperature applications. (currently not shown in the table below.) After choosing materials, you determine which model and how many links will be needed. Assistance can be provided, or the sizing program below can be used.

Glass Reinforced Plastic |
316 Stainless Steel |
-40 to +250 |
Suitable for environments where the corrosion resistance of stainless steel hardware is required. |
| N |
NITRILE |
Glass Reinforced Plastic |
Steel zinc dichoromate |
-40 to +210 |
Resistant to most hydrocarbons, oil, gas, jet fuel, and many solvents. |
| NS |
NITRILE |
Glass Reinforced Plastic |
316 Stainless Steel |
-40 to +210 |
Same as above but with the corrosion resistance of stainless steel hardware. |

1. Wrap the belt
around the pipe.
Then connect
the first and last
links. |
|
2. Slide the
assembly into
the space
between the pipe and wall. |
 |
3. Gradually
and sequentially
tighten the bolts.
Tighten each
bolt 2-3 turns
making 5 to 9
passes com-
pletely around
the pipe. |
