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

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

Ver­si­ons

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.
