NEWTRY 10pcs Springs for NEWTRY All Kinds of Water Powered Flow Dosing Pump Hydraulic Chemical Fertilizer Injectors

I highly recommend completely disassembling the injector pump to simplify spring replacement.

Got my injector back up and running with these! Easy to install once I took apart the injector fully.

as described but overpriced

Worked perfectly to replace broken spring in my fertilizer injector pump. Very quick delivery!!

I use this product for over a year with no problems and finally a spring broke inside I love you but it had a lot of wear from use, they were quick to respond and showed me what I need to fix it, it has been a great product for my greenhouse

dont know what type of metal these springs are made off, but it's not adequate to dosing pumps. only last one day that brake.
