ProGrow Connectors for 4/6mm hose with 1/8 inch thread

Metal ProGrow coupling with a nut for fixing 6mm diameter hoses.

Thanks to the cap, we have the possibility of fixing in such a connector also more flexible hoses, eg silicone hoses and those most commonly used in the CO2 technology for the aquarium – polyurethane (PU) hose. The fitting has a 1/8 “outer thread.
