Model "R" End Seals are available in five (5) different sizes to accommodate a wide range of carrier/casing diameter combinations. A unique "cone" design, with molded-in dimensions, is easily cut to size for a correct fit on the carrier pipe. Stainless steel bands are included for clamping the Model "R" end seal to both casing and carrier pipes.

Manufactured from 1/8" (3.18 mm) thick high-quality EPDM rubber, Model "R" end seals are extremely robust, resistant to a wide variety of environmental conditions and may be used to prevent the ingress of moisture and soil into the annular space between carrier and casing pipes.

Features & Benefits

Hardware

304 stainless steel bands with work screws

Note:

Simply cut the seals at the closed end to the measured external diameter of the carrier pipe. (Note: the printed sizes are marked on the end seals.) Push the end seal over the outside of the casing pipe and the carrier pipe and fasten with the included stainless steel bands.

1. Prepare outside surfaces by removing dirt from casing and carrier pipe.

2. After carrier pipe is inserted into casing, slide small end of end seal over the carrier pipe with stainless steel banding clamp. Large end should face casing.

3. Position large end of end seal over the casing pipe.

4. Position banding clamp approximately 1” from the end of the casing pipe and then tighten onto the end seal.

5. Fold end seal in an “S” shape so it will extend into the casing.

6. Position banding clamp approximately 1” from the end of the end seal on the carrier pipe and then tighten. (Make sure the end seal is folded into the casing, to relieve stress during backfilling and allow for expansion and contraction movement.)

7. Repeat steps 1, & 3 - 6 on other end of casing.

Model "R" end seals shall be manufactured from a minimum 1/8” thick synthetic rubber. Banding clamps shall be 304 stainless steel with worm screws. End Seals shall be PSI Model "R" as manufactured by PSI-Pipeline Seal and Insulator, Inc. A copy of current ISO 9001:2000 registration shall be provided with material submittal.

How to Order

There are five Models to choose from. Select the appropriate end seal for your casing pipe O.D. (colored bars below), then verify that your carrier pipe O.D. is within the cone's diameter range.

Other PSI End Seals
  

Individually designed to accommodate custom carrier / casing combinations. Made of 1/8" thick, specially compounded synthetic rubber for long life and easy installation.

Specifically designed for existing installations. Simply remove plastic backing from self-curing rubber and press exposed surfaces together. Available for all carrier/casing differentials.

Made of special synthetic rubber for long life and easy installation, the highly flexible "S"-shaped seal is available for ANSI steel pipe specifications. Band locating ribs are on the outside, with special sealing ribs on the inside under the band to pre-vent leakage.

This model has been developed exclusively for situations involving a need for fire retention. They are applicable to casing through dikes in tank farms, fire walls or wherever a casing may be in a fire prone area.
