Nws yog ib qho tseem ceeb kom nkag siab tias O-rings yog dab tsi thiab yog vim li cas lawv thiaj li xaiv qhov kev xaiv foob.Ib qho O-ring yog ib puag ncig, cov khoom zoo li lub khob noom cookie uas yog siv los tsim lub foob ntawm ob qhov chaw hauv ib puag ncig uas muaj zog heev.Thaum txhim kho kom raug, O-ring foob tuaj yeem tiv thaiv ze li ntawm tag nrho cov kua dej los ntawm kev khiav tawm hauv ob lub xeev kua thiab gaseous.
Cov khoom siv ntawm O-rings nyob ntawm lawv daim ntawv thov, tab sis cov khoom siv rau O-rings muaj xws li nitrile, HNBR, fluorocarbon, EPDM, thiab silicone.O-rings kuj tuaj nyob rau hauv ntau qhov ntau thiab tsawg vim tias lawv yuav tsum tau ua kom haum rau kev ua haujlwm kom raug.Cov ntsaws ruaj ruaj no yog hu ua O-rings vim lawv lub voj voog lossis "O-shaped" hla ntu.Cov duab ntawm O-ring nyob twj ywm zoo ib yam, tab sis qhov loj me thiab cov khoom siv tuaj yeem hloov kho.

Thaum ntsia, O-ring foob tseem nyob rau hauv qhov chaw thiab yog compressed nyob rau hauv lub sib koom ua ke, ua ib tug nruj, ruaj khov.Nrog rau kev txhim kho kom zoo, cov khoom siv, thiab qhov loj me, O-ring tuaj yeem tiv taus lub siab sab hauv thiab tiv thaiv cov kua dej los ntawm kev khiav tawm.

Peb muaj cov qauv sib txawv xws li C-1976 / AS568 (USA size standard) / JIS-S series / C-2005 / JIS-P series / JIS-G series.
