Hydro FlowNetafim 17 mm Insert Coupling (25/Bag)

It does what it is supposed to. It's a very flexible system, the parts are relatively inexpensive and very robust. You need a heat gun or something like it to soften the tubing so it slides onto the fittings, but once on it won't come off. I can't see a way this system could be better

If you have a Netafim based drip irrigation system, these are the real deal. They fit great, and are less expensive here than anywhere else I could find them.

I ordered 2 packs and kept one and returned one, I used 4 on the first pack, still have 25 count left, the second one I returned has 28 counts and I returned the unused one. They seem to give you a few extra for both packages. The size labeled as 17 and fit Rainbird 1/2' dripping line very very tight, a little bit too tight that your hand hurts after just doing 4. I ended up using Rain Bird BC50/4PKS even though they cost more. It fit way easier if you need to fit a few dozens. The seller is very good on the refund, I got the refund to my account even when the return shipment is still in transit.

Fits like a glove. I originally bought the same product made by rainbird in a big box store. It would fit in but just a little too big for my netafim tubing. I should have bought this first.

Splices work great in repairing cuts to our irrigation system. A real lifesaver!
