These Gilmour hose menders and couplers are absolutely brilliant. I discovered them last season, after messing around for years with regular brass fittings and hose clamps. Made of nylon, with stainless steel screws, they’re light, durable, and feel like precision parts. Inserting and screwing tight are both smooth and straightforward. They’re no more expensive than brass couplers, and they eliminate having to use a separate clamp. I use mainly the couplers, to make up custom pieces of hose (the top row is for 5/8″-3/4″ hose, the bottom for 1/2″), while the menders can be lifesavers if you accidentally slice a hose. I’ve yet to install a full drip irrigation system, so my small-scale irrigation is intimately connected with regular garden hoses. I suspect even with a fully installed irrigation set-up, hoses on the tiny farm will still play a part, and these will come in handy. I have tried one other plastic connector of similar design, but it broke. I’d recommend this particular brand since it’s the one I’ve field-tested with great success.
