4" to 1 1/2" threaded Bushing reducers

Unread postAuthor: Hayseed_Andrew » Wed Nov 29, 2006 4:49 pm

Probly gonna get flamed for this, but. Do all fittings this big have to go into a coupler, or can I find some that fit into the pipe itself, if so, where?

P.S. Don't say Home Depot. or dont say that I should use the search function because I have been looking for stuff for over 7 months and I'm kinda getting tired of it.

yes, they do have to go into a coupler.
go to here, http://www.sprinkler.com/buy/4_40_fittings . pressure rated, reliable shipping. decent price.

spudstuff, dont open your mouth. we all know you can get them for
"half that" from your "sources" on ebay, but this place always has them in stock, and they are all pressure rated for sure.

Yes. They manufacture the pipe itself so that the outside is perfectly smooth and the right diameter, while the inside isnt made with as much presicion. If they made pipe fittings to go inside it wouldnt always fit perfectly. Basically, you need a coupler

Like Schmaman said, you have to use a coupler/tee/threaded adapter or a bell end to stick a bushing into. No getting around that. As to the fast shipping, there are stores online that you can buy from and they'll ship quick with cheap prices. I think there's one here in Utah that ships in 2 days.

For all pipe connections consist of a male connection fitting into a larger female slip connection. If comparing this to the human reproductive system helps you remeber this, so be it. Anyway, the smaller male connection is either going to be a pipe, or a fitting with a extruding male slip connection this being reffered to as 'spigot'. The female slip joint accepting the male connection is referred to as 'socket'.

The reason why they dont make fittings to fit the interior of a pipe is that they change from manufacter to manufacter, and change in thickness to accept different applications. So any commerically aviable socket fitting is only intended for accepting the exterior of a pipe. Now I must note that 2" sch 80, and 1.5" SDR-21 are close in size allowing you to slide one in the other. So naturally you can fit a 1.5" spigot fitting into the interior of a 2" sch 80 pipe. Although this was never intended by the manufactuers.

Your two means of reducing/ increasing to a different size pipe is threw a 'reducer' or 'bushing'. Reducers generally have a shorter socket depth so they are not commonly used in pneumatics. A reducer consists of two 'socket' connections, while a bushing has a 'spigot' connection on the larger connection, and a 'socket' on the smaller connection.

As to where to purchase it, Id first suggest a local plumbing house. Just a bit of advice, dont do business with ACE hardware. There PVC sucks, and so do there prices. Also when buying fittings dont buy any extremly shiny, yellowish, or fittings with a unsmooth surface finish. Usally you can sort threw the bins of fittings to get the ones you want. Hope that helps.

One last thing.

They don't make a 4x1-1/2" bushing with any type of outlet connection. Smallest they go is 2". You'd have to combine a 4x2" spigot x socket bushing and then a 2x1-1/2" spigot x FNPT bushing to get what you want.

Unless he uses the trick where 3" couplers fit in 4" pipe. Then he can stick a 3x1.5" bushing in there. That would also take care of your request for putting this all inside the pipe.

Take a look at my <a href="http://launchpotatoes.com/index.php?act=viewProd&productId=6">Streamlined Simple Combustion</a>. I use that nifty trick on there and it works beautifully. <a href="http://www.spudfiles.com/forums/viewtopic.php?t=2430&">(More info here.)</a>

Special care needs to be taken when doing this with pneumatics though. Also be sure the lips of the pipe and fitting are bevelled before your glue or else they can jam up and not slide together.
