I'm starting this thread because I don't want to hijack this thread. I have always used either Rainbird MPTxBarb fittings and Marlex elbows or the Lasco Blue twisters (We now use the Lasco ones exclusively). We use Hunter swing pipe. I have never personally had any swing joint connection blow out on me. It takes only a few seconds to get the swing pipe all the way over the barb, and then I don't think 1000 psi could get it off. I have seen scary things though, thin wall 1/2 tubing like Rainbirds .700 using swing joint barbs and a hose clamp...or hose clamps on swing joint. We had one guy who would only get the fitting about a 1/4 over the barbs, and even those didn't blow out (though I caught him early on). So basically, what I'm getting at is that I don't believe using a SCH80 nipple and marlex ell's is necessary on 1/2" and 3/4" inlet heads. Thoughts?
