The seal­ing action of these stat­ic seals is achieved by elast­ic deform­a­tion of their cross-sec­tion in a hous­ing designed to DIN 11864. This type of seal is suit­able for all auto­mat­ic and manu­al clean­ing processes.

In food pro­cessing, joint­ing of pipes and flanges always rep­res­ents a weak point in rela­tion to hygiene. There­fore aseptic pipe joints are stand­ard­ized in DIN 11864.

Seal­ing between pipes and flanges

By apply­ing that stand­ard, it is pos­sible to use the groove geo­metry and groove dimen­sions for non-stand­ard pipe or flange dia­met­ers irre­spect­ive of the nom­in­al size of the pipes.

The con­struc­tion is shown oppos­ite as “flange seal­ing”. Because the groove geo­metry is com­plex in these cases, this type of stat­ic seal is only spe­cified for cross-sec­tion dia­met­ers of 3.5 and 5 mm.

Seal­ing between rods and pistons

To enable the point of con­tact between pis­ton and pis­ton rods to be sealed on the same prin­ciple, a vari­ant of this seal not spe­cified in the stand­ard is pos­sible. It is shown oppos­ite as “pis­ton rod sealing”.

Com­pounds and coatings

Manoy­De­tect® – Met­al detect­able materials
In food pro­cessing and pack­aging industry applic­a­tions Manoy­De­tect® enhanced mater­i­als will allow detect­or equip­ment to identi­fy for­eign mat­ter in the pro­cessed mater­i­al res­ult­ing from a dam­aged seal. Depend­ing on the sens­it­iv­ity of the met­al detect­or fit­ted this offers a high degree of safety and will pre­vent con­tam­in­a­tion of the pro­cessed material.

Manoy­Coat® – Anti-fric­tion coating
Manoy­Coat® coated O-rings offer spe­cial assembly and dis­as­sembly advant­ages due to their anti-fric­tion prop­er­ties. For auto­mated assembly, the coat­ing provides smooth feed­ing. Vari­ous coat­ing types are avail­able for stat­ic applic­a­tions (103, 105 and 110). Coat­ings 101, 102 and 106 are suit­able for O-rings in dynam­ic applications.

ManoyPer­fluor® – For aggress­ive chemicals
The ManoyPer­fluor® O-ring com­bines the typ­ic­al prop­er­ties of elast­omers with the almost uni­ver­sal res­ist­ance of PTFE. ManoyPer­fluor® com­pounds are suit­able for use with aggress­ive chem­ic­als and vapours and at tem­per­at­ures up to +320 °C. Also ideal for aseptic applications.

• Com­pletely closed sur­faces without any undercuts 
• Sur­face easy to clean 
• For wide pres­sure and tem­per­at­ure ranges
• For almost all liquids, pastes and gases
• Easy to assemble/disassemble

From -130 to +320 °C

but depend­ent on the O-ring mater­i­al in each case.
