Ugereranije nairembo, isi ya valve no kugenzura igishushanyo mbonera, amateka yumupira wumupira ni ngufi cyane.Nubwo ipatanti ya mbere yumupira wamaguru yatanzwe mu 1871, bizatwara imyaka 85 kugirango umupira wumupira ugende neza mubucuruzi.Polytetrafluoroethylene (PTFE, cyangwa “Teflon”) yavumbuwe mu gihe cyo gutegura igisasu cya kirimbuzi mu Ntambara ya Kabiri y'Isi Yose, kizaba umusemburo wo gutangiza inganda z’umupira.Imipira yumupira iraboneka mubikoresho byose kuva kumuringa kugeza ibyuma bya karubone nicyuma kitagira umwanda kugeza zirconium.

Hariho ubwoko bubiri bwibanze: imipira ireremba nudupira twa trunnion.Ibishushanyo byombi byemerera kubaka imipira ikora neza kuva ¼ ”kugeza kuri 60” kandi nini.Mubisanzwe, igishushanyo kireremba gikoreshwa kubintu bito bito kandi bito byumuvuduko, mugihe ubwoko bwa trunnion bukoreshwa kubintu binini kandi binini byumuvuduko wa progaramu.
