Locator Seal Sub

The Locator Seal Sub comes with a No-Go, designed to limit the downhole travel of the seals in a packer or profile nipple. The Seal Sub is made up to the packer and usually has a tailpipe and other accessories such as nipples, wireline re-entry guides or other equipment installed with it. Coiled tubing is normally landed in compression to prevent seals from moving upward, and additional seals can be added to ensure sealing in the Seal Sub.
