I was planning to run 3/4" 160 psi IPS poly pipe from my well to the utility room inside my house, but from what I've read in other threads here, I'm concerned that the coupling from the poly to 3/4" PEX might blow out or leak badly and do a lot of damage (wood floors throughout). I understand that brass is the best of the barbed insert fittings, but I gather that pack-joint fittings for CTS poly pipe are better and that such fittings might exist for at least one kind of IPS pipe as well. Interestingly, I can't find any fittings that are rated for 160 psi; they seem to max out at 100. My well shouldn't produce more than 60 psi, but the relatively low psi ratings for the fittings make me wonder about their resistance to pulling out.
1. What would you estimate to be the percentage probability that a brass barbed fitting would fail after being installed properly, with heat and two clamps on opposing sides?
2. What would that probability be for a pack-joint fitting on CTS poly pipe?
3. Here's the poly pipe I bought, which I can still return:

Where might I buy the most secure fitting available for this pipe?
