APPLICATIONS

Pre­ci­sion O-rings are used as stat­ic radi­al or axi­al seals in all sec­tors of mech­an­ic­al, plant, auto­mot­ive and equip­ment engineering.

The seal­ing action of the O-ring is achieved by elast­ic deform­a­tion of its cross-sec­tion in a suit­ably designed hous­ing. The pres­sure of the flu­id being sealed also squeezes the O-ring. The elast­omer trans­fers the pres­sure evenly in all the effect­ive directions.


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. Some of the coat­ings are also suit­able for dynam­ic applic­a­tions. FIND OUT MORE >

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.

CHARACTERISTICS

  • For wide pres­sure and tem­per­at­ure ranges 
  • For almost all liquids, pastes and gases 
  • Space-sav­ing construction 
  • Easy to assemble/disassemble 
  • Close size increments 
  • Also avail­able in a PWIS-free ver­sion (free of any sub­stances that inter­fere with paint wetting)

TEMPERATURE RANGE

From -130 to +320 °C

Ver­sions

met­ric

Due to the prac­tic­ally infin­ite num­ber of dimen­sion­al vari­ants between inside Ø (d1) and cord Ø (d2), there is gen­er­ally no con­sist­ent logic to the series structure.
Please tell us the dimen­sions you want for d1 and d2.

accord­ing to ISO 3601

Cov­ers an inside Ø range (d1) from 0,72 to 694 mm.
The cord Ø (d2) is gradu­ated in five sizes:
1,78 - 2,62 - 3,53 - 5,33 - 6,99 mm.

In stat­ic applic­a­tions O-rings can be com­pressed by 3 % and expan­ded by 5 %.

Install­a­tion information

  • Lead-in cham­fers and roun­ded edges are required for install­a­tion of the O-ring.
  • Note: The lengths giv­en for the cham­fers dif­fer from ISO 3601 to ensure smooth installation.
  • The O-ring must not be pushed over sharp edges, thread crests, cross holes, key­ways or rough surfaces.
    If this can­not be avoided for struc­tur­al reas­ons, these points must be covered, e.g. with adhes­ive tape.
  • Do not twist the O-ring dur­ing install­a­tion and avoid any rotary motion!
  • An uncoated pre­ci­sion O-ring must not be stretched more than 100% for installation.
