Darton Dry Sleeves 85mm - 86mm

Dry sleeves are named so because the sleeve body is not exposed to any cooling liquid within the block and is always installed in a block with an interference fit. The usual interference value depends on the application and method of install. Darton recommends .001 - .002 interference on like material, i.e. iron sleeves in an iron block. When dissimilar materials are involved such as iron sleeves in aluminum blocks, and interference of as much as .003 can be used, however, differential temperatures must be used for installation and the block must be perfectly prepared both dimensionally and surface finish.
