SL-J-2601 Hygienic Sealing Nut
The SL-J-2601 is a SUS316L hygienic sealing nut with a closed dome and smooth transitions that keep water, dust, and residue off exposed threads; the blue sealing ring at the base seals against the mounting surface - protection up to IP69K depending on assembly structure and sealing compression.
- SKU : SL-J-2601
Hygienic fasteners close the gaps where conventional bolts and nuts trap product residue and cleaning liquid. Smooth, rounded geometries support clean-in-place and washdown routines; SUS316L and HNBR sealing elements resist common cleaning agents. Final ingress protection depends on the installed joint - confirm by test in the application.

How To
1. Cap exposed threads hygienically
The closed dome and smooth transitions keep water, dust, and residue off exposed threads.
2. Seal against the mounting surface
The blue sealing ring at the base seals against the mounting surface - protection up to IP69K depending on assembly structure and sealing compression.
3. Support clean-in-place routines
Smooth, rounded geometries support clean-in-place and washdown routines where conventional nuts trap debris.
4. Choose SUS316L for the washdown line
SUS316L resists common cleaning agents; confirm the body against salt-spray exposure on coastal or chemical-adjacent plants.
5. Test the installed joint
Final ingress protection depends on the installed joint - confirm by test in the application.
