I-Fin icindezelwa ngomugqa wokucindezela we-fin bese kuthi ipuleti lokugcina licindezelwe ngomugqa wokucindezela wamandla njengokwelashwa kwangaphambili, ngenkathi kugotshwa, kunqunywa, futhi kusontwa ithubhu le-aluminium ngomshini wokugoba we-Auto Al Tube kanye nomshini wokugoqa ogoqekayo. Bese kuthi ipayipi lifakwe futhi linwetshwe ngomshini wokungeza we-Double Station Station kanye nomshini wokunweba ukuze kulingane ipayipi ne-fin. Ngemuva kwalokho, i-interface ishintshwa nge-Cooper Tube kanye nomshini wokuwelda we-Aluminium Butt bese kuthi ipuleti lokugcina lihlanganiswe ngomshini wokuhlanganisa we-Side Plate. Ngemva kokutholwa ngomshini wokuhlola ukuvuza kwamanzi, iyunithi isuswa amafutha ngomshini wokuwasha kanye nedivayisi yokufutha.
