Dextube sika amashubhu umfutholuketshezi futhi instrumentation amashubhu e olubandakanya ukugqwala ukumelana lezinsimbi engagqwali futhi nickel Alloys esehlanganise diameters ngaphandle kusuka (OD) 3.175 ukuze 50,8 mm (1/8 "2"). Zonke osayizi ayanikezelwa nge evele bushelelezi naseduze tolerances ntathu ekunciphiseni ingozi ukuvuza uma kuxhunywa amashubhu nge couplings.
