Ho Khetha Mofuta o nepahetseng oa Hydraulic Fitting Thread
Ha u khetha mofuta o loketseng oa khoele ea hydraulic, nahana ka lintlha tse latelang:
✅Litlhoko tsa Tsamaiso
Utloisisa khatello, mocheso, le litlhoko tsa phallo tsa sistimi ea hau ea hydraulic ho fumana mofuta o loketseng oa khoele.
✅Ho lumellana ha Karolo
Netefatsa hore mofuta oa khoele oa fitting o tsamaellana le mofuta oa khoele ea motsoako ho netefatsa khokahanyo e nepahetseng le e sireletsehileng.
✅Lintlha tsa Kopo
