90 Degree Forged Elbow

Do they make this item in 3/4 x 3/4?

https://smile.amazon.com/Anderson-Me.../dp/B006PKL03A

Or something similar?

I can't seem to find it anywhere (aside from a couple of terribly reviewed ones on Amazon).

Thanks!

Yes, they do exist. I searched online for "3/4 x 3/4 male elbow" and many sellers appeared, including Amazon.

Hi newbie -

Here is a link to one. But if you are using it for a potable water application there may be some kind of regulation where you live requiring low lead brass. I donít see any in low lead 3/4 elbows MNPT x MNPT.

That would be an expensive fitting to use in basic plumbing. What are you connecting ?

Thanks and yeah, I don't want to pay $50... It's to possibly connect a hose to a dehumidifier (if I don't go the route of vinyl tubing). The hose is probably flexible enough to come straight out of the unit and just turn it to the side, but I figured a 90 degree elbow would make it that much easier...

If you read those reviews for those it doesnít sound good. Also, it sounds like they are saying those are straight threads not NPT. But maybe straight threads would be OK and although the original post referenced MNPT maybe NPT isnít necessary or appropriate in this case. The post didnít really specify how the 90 would be used.

I think dehumidifier drains use straight thread to connect to a hose Ė so I guess we would need to know how and where a 90 elbow would be used in that case.

I just went down the basement to see how I set up the drain for my dehumidifier (couldnít remember anything Ėlol). I used an old washing machine hose with the end hanging over a floor drain. I guess it works OK Iíve never seen any leaks.

Thanks everybody. I saw that one on Amazon and reviews were bad. I can't seem to find a good 3/4 x 3/4 anywhere.

I'm looking for a 'regular' threaded (to use with a garden hose) elbow, just like the one here: https://smile.amazon.com/Anderson-Me...006PKL03A?th=1 (which gets good reviews but isn't available in 3/4 x 3/4).

In terms of the washing machine hose, not a bad idea. Is that more flexible than a garden hose?

Hi newbie -

The washing machine hoses arenít very long. I donít even know why I keep old ones around (lol Ė nuts), so my dehumidifier was close enough to a drain, so thatís why I used it.

But the fitting you are referring to I think would not work to connect into a garden hose. National Pipe Thread (NPT) is tapered thread. A garden hose instead uses Garden Hose Thread (GHT) which is straight thread. When you connect using straight thread, like connecting your garden hose to an outdoor hose bib for example (which are also straight thread), the connection is made water tight with a washer.

But when you are connecting tapered threads together, like a male pipe which has MNTP threads, into a female fitting which has FNPT threads, the idea is as you tighten, the threads themselves make a watertight connection. You use tape or pipe dope also on the threads in that case to complete the connection.

You can read a lot of debate about whether the tape/pipe dope in that case is just a lubricant so you can push the threads deep enough and thus make the connection tight enough and thus watertight, or whether tape/pipe dope is actually the sealer. That debate is above my pay grade.

Here is a little info on threads:

This looks to me like it would work if you wanted to make a 90 degree turn for some reason.
