Icyitonderwa: kubera ko umuyoboro wimbere ari NBR rubber tube na elastique, nibisanzwe ko amakuru yapimwe agira kwihanganira runaka (Ndetse nibicuruzwa byuma bikoreshwa muri roketi zo mu kirere bifite kwihanganira, nyamuneka ubyumve).
Reba indangamuntu mu mbonerahamwe ikurikira kugirango ubone ibisobanuro birambuye (igice cyindangamuntu ID ni santimetero, kandi niba ihinduwe muri sisitemu ya metero, ikenera * 25.4mm, ni yo mibare yatanzwe hejuru)
