Oakum Spun Tar
Oakum is made up of short lengths of shredded rope or hemp fiber that has been oiled or tarred. It is used in pipe patching operations as caulking or as a gasket when applying soft patches. In plugging operations it is used to plug holes and wrap around a plug or wedge prior to inserting into a split seam or crack in damaged decks, bulkheads and overheads. Oakum is supplied in either a box of three 5-pound rolls or one 50-pound roll. Only one pound is required in the pipe patching, plugging, and repair locker tool kits and should be stored in a protective package. |
What is this? Define.
|
|
