Sleeve-within-a Sleeve


Siftex Sleeve-within-a-Sleeve™ connectors provide better dust control,
easy installation, longer life and are more cost-effective.

Traditional flexible sleeves may allow product to become trapped between the inside
of the sleeve and the outside of the pipe. Hose clamps at the sleeve bottom and steady product build-up may combine to cut the sleeve material causing leaks and premature sleeve failure. The result is more dust, lost product, more housekeeping and replacement sleeve expense.

Siftex’s Sleeve-within-a-Sleeve design eliminates leaks resulting in longer sleeve life!

  • Eliminates dust and product leakage.
  • Reduces housekeeping and maintenance.
  • Reduces sleeve wear.
  • Increases safety.


Our sleeve-within-a-sleeve design eliminates product build-up. It combines an outer dust-control sleeve with a free-end inner sleeve to keep powder, pellets
and other loose materials flowing. The inner sleeve extends a few inches into the inside of the spouting. Only the inner sleeve is in contact with the product.
The outer sleeve is clamped top and bottom for dust-free seal.
Siftex sleeve-within-a-sleeve connectors come in a variety of materials and sizes.
