doesnt dura make those new pvc fittings that have the barb elbow built in? or is that dawn? those are cool...

 

We use a mix, but we don't use insert fittings (PVC)

When we do any poly work, all fittings are brass.

 

you talking about those new manifold fittings that are swivel and have the o rings in them?

Dura makes those

but i was talking about regular insert

I think Koster is talking about these, from Dawn:

 

anyone have any opinions?

I'm only really interested in the insert fittings... I've almost always used spears fittings but another supplier has recently opened up and sell Dura.

they swear by Dura being a superior product but I like Spears more. I don't know why though... it might just be because I'm used to them.

I work at a distributor and to be honest with you it's just a fitting. I personally like Dura...and we sell both...the barbs they have on them I think grip better. But I this is preference.

As far as Irrigation goes I would say #1 is heads,valves controller brands, #2 Customer Service, #3 Stock (what you need,when you need it) #4 Price

You just have to weigh the differences. Is a brand of a fitting that important to you?

 

thankd bdb....

yea it wasn't anything I was considering when deciding which distributor to go with... I was just wondering if people had a preference.... in the picture attached, the dura fitting is on the right...

i like the fact that the spears fittings is shorter because you need less room to work with... if you look though... the barb length is the same the dura fitting just has more room in the middle

 

OK we must have older parts. There are more barbs and they are closer together on the other spears parts. Must mean Dura has something....but shorter would be nice!

 

Dura has some Sch 40 fittings that will nest into other fittings, in tees and elbows.

We use a lot of them, SCH 40 male adapters nested into a tee for tighter manifolds etc.

 

I just started using dura, and have been using spears for years. So far the dura fittings seem to be made with every bit of quality I have seen in spears. The jury is out in my opinion. Time will tell.

 

Can anyone supply a side-by-side photo of their 3/4 Marlex elbows? Spears has made theirs thinner, which bothers me a bit. Haven't seen what Dura and Lasco are doing with theirs.

I don't have any side X side pics but we get both Spears and Lasco. I can't tell much of the difference between them except for one freaky thing. The Spears is much easier to thread onto our SCH 80 nipples in the 3/4" size only. The 1/2" and 1" sizes thread on with about the same ease.

 

We just installed a 12-valve irrigation manifold using Dura swivel multi port manifold components, supported every 2 valves.
This has got to be the softest plastic ever - particularly at the ends where interfacing to non-Dura MPT and FPT: you touch it and the threads leak or let go. We had to use lots of teflon tape at the ends - to stop the leaks. Even Several dura-to-dura connections leak, and one cannot tighten too much or the threads pop. i didn't measure the depth of the threads, but perhaps they are more shallow than other MPT/FPT threads.

 

We fix a lot of those manifolds that others have installed.
Im old school, I still glue together a manifold

 

17 year old thread.....17 years......

 

My experience with the Dura manifolds, is that the male adapters used for threaded into valves, dont rely on the threads for leak prevention... theres an o-ring that seals to the threads facing. So its designed to be shallow threads that sink all the way in, so the faces of the two fittings get sealed with that o-ring.

And you shouldnt be putting any teflon tape on the threads at all, since that's not the sealing surface.
