1. iringi isesekeli esivame kakhulu ekufakweni kombhobho. Umsebenzi wawo omkhulu ukuvala indlela yokugeleza nokuvikela ukuvuza koketshezi noma kwegesi. Kweminye imibhobho, ibuye ibe nomsebenzi we-buffer. Imibhobho esemzimbeni yethu isetshenziswa kakhulu kuma-O-rings enziwe ngenjoloba ye-nitrile noma i-fluorine rubber. Phakathi kwabo, iraba ye-fluorine inezici zokumelana nokushisa okuphezulu nokumelana nokugqwala, kepha izindleko zayo ziphakeme kakhulu, ngakho-ke ungakhetha ngokuya ngezidingo zakho.

O-izindandatho imikhiqizo esetshenziswayo. Ukuzisebenzisa ezindaweni ezinzima isikhathi eside kuzonciphisa isikhathi sabo sokuphila. Sincoma ukuthi uthenge ezinye izingxenye zokungcebeleka zamasongo amise isikhathi uma ziqukethe ama-O-rings. Kufanele silinde isikhathi sokuyishintsha ngesikhathi ukuze sigweme ukulahlekelwa.
