Sentry’s BO-10 adapter is the solution for extreme tubing string weight applications for a coup[ling type adapter. This adapter is designed with an ACME load nut for larger trees. This allows for the tree to be made up without rotating the tree and prevents any thread galling that may occur between dissimilar NACE coupling and adapter materials. Additionally, it incorporates internal “S” seals on the upper extended neck. Like the BO-2 these adapters also employ the TC-1W wrap-around pack-off. This system is employed when an operator wants to reciprocate tubing as part of the completion process.
