Typical Application
Installation
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.
- Prepare outside surfaces by removing dirt from casing and carrier pipe.
- 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.
- Position large end of end seal over the casing pipe.
- Position banding clamp approximately 1″ from the end of the casing pipe and then tighten onto the end seal.
- Fold end seal in an S shape so it will extend into the casing.
- 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.)
- Repeat Steps 1, & 3 – 6 on other end of casing.
