In understanding how a hygienic seal works, it’s becomes important sometimes to understand why a hygienic seal fails. Either Over-Tightening or Under-Tightening a seal will cause serious problems to a sanitary system.
An over-tightened gasket will:
- Extrude into the I.D. obstructing flow and collect soil
- Extrude beyond the O.D.
- Crack, tear and rip and hold bacteria
- Become permanently deformed jeopardizing sealing surface and product integrity
