The New Hotness

Replacing the sun-rotted hose for Mary’s garden called for a new grip, because of course all hose fittings are different:

Garden Hose Fitting Grip - installed — Garden Hose Fitting Grip – installed

The ridges on the fitting looked close enough to half-cylinders and the fitting wasn’t tapered enough to worry about:

Hose Fitting Grip - simple - solid model — Hose Fitting Grip – simple – solid model

The OD came from the original grip, because it neatly fits Mary’s hand, and the nubbles are round-end cylinders.

Got it done the day after the old hose split, glued it on the hose with E6000+, installed it the next morning, whereupon the weather delivered three inches of rain. It’ll get screwed onto the faucet in a few days …
