Gukaraba ni ibyuma cyangwa plastiki.Ihuriro ryujuje ubuziranenge risaba gukaraba ibyuma bikarishye kugirango wirinde gutakaza mbere yumutwaro bitewe no gukonjesha nyuma yumuriro.Gukaraba nabyo ni ingenzi mu gukumira ruswa ya galvanike, cyane cyane mu kubika imigozi y'ibyuma hejuru ya aluminium.Bashobora kandi gukoreshwa mugusimburanya porogaramu, nkibisobanuro.Imashini isunika ikoreshwa mugihe ibintu bizunguruka bidakenewe haba mubiciro-byerekana imikorere cyangwa kubera umwanya uhagije.Ipitingi irashobora gukoreshwa kugirango igabanye kwambara no guterana amagambo, haba mu gukomera hejuru cyangwa gutanga amavuta akomeye (ni ukuvuga kwisiga wenyine).
Inkomoko y'ijambo ntiramenyekana;ikoreshwa rya mbere ryanditse ryakoreshejwe muri 1346, ariko, ubwambere ibisobanuro byayo byanditswe ni 1611.
Ibikoresho bya reberi cyangwa fibre ikoreshwa muri robine (cyangwa robine, cyangwa valve) nk'ikidodo cyo kumeneka kw'amazi rimwe na rimwe bavugwa mu mvugo nk'abamesa;ariko, mugihe zishobora kuba zisa, gukaraba hamwe na gasketi mubisanzwe byateguwe kubikorwa bitandukanye kandi bikozwe muburyo butandukanye.
Abamesa benshi barashobora gushirwa mubwoko butatu bwagutse;
Gukaraba neza, bikwirakwiza umutwaro, kandi bikarinda kwangirika hejuru yubutaka, cyangwa bigatanga ubwoko bumwebumwe nkamashanyarazi.
Amamesa yo mu masoko, afite imiterere ihindagurika kandi akoreshwa mukurinda gufunga cyangwa kurekura kubera kunyeganyega
Gufunga ibikoresho byo gukaraba, birinda kwizirika cyangwa kurekura mukurinda kuzunguruka kudacometse kubikoresho bifunga;gufunga abamesa mubisanzwe nabo bakaraba.
