Dielectric Hose Coupler

Many hoses come with aluminum fittings. When attaching these to brass hose bids the dissimilar metals cause a cathodic reaction (the aluminum corrodes) that causes the fitting to seize and makes disconnecting the hose difficult.

This simple insulator prevents that reaction.

Print in PET-G for better sun / heat resistance with 4 perimeters (makes the threads cleaner) and 40% in-fill.

Make sure to use a hose washer on the female end.
