eheim 1262 tubing sizes?

saltyfun · 04/27/2006, 09:59 AM

What size is the tube on the pressure side, 5/8" ?

How do I get that hooked up to my 1" return line?

Thanks,
Dave

If I recall correctly you can plumb the pressure side with the 1" barb, or the 3/4" barb. I used 1" tubing and the 1" barb. You can get a 1" barb for your return pipe at home depot to plumb it in. Alternatively, the threads are 3/4", and you can screw in a 3/4" to 1" fitting and then plumb normal schedule 40 or schedule 80 to the bulkhead. I'd recommend flexible because it is a lot quieter than when I had it plumbed with pipe. I'd also recommend using a union in the plumbing regardless of whether you go with flexible tubing or hard pvc.

I thought they were metric?

me too???

I found some 5/8 tubing that fits great and some 5/8 barb to 3/4 thread at Menards.

I bushed my 1" down to 3/4" , it looks and works great!

Thanks

Are you sure you are talking about the 1262? They have odd sizes (metric?) on the smaller pumps. The 1262 has 3/4" threading on the input and the output. Both barbs are 3/4" threaded but one is 3/4" on the barb end, and the other is 1" on the barb end. I think I used 5/8 on my 1250.

crumbletop · 04/27/2006, 04:00 PM

Yes. I just checked. My 1250 uses 5/8 OD, 1/2 ID tubing.

Jack

saltyfun · 04/27/2006, 04:03 PM

1260 and 1262 came with a 3/4 barb inlet which I used 1" ID tubing

The outlet on both takes 5/8 ID tubing perfectly.

crumbletop · 04/27/2006, 04:09 PM

You've got me confused. I have both the 1262 and the 1250. Here is a marinedepot link that shows the input and output sizes:

http://www.marinedepot.com/aquarium_...ds.asp?CartId=

I have the tubing right in front of me, and the 1262 (a 900+ gph pump) uses either a 3/4" or 1" barb on the output end (they are interchangable with the same size threading), or you can plumb using 3/4" threaded fittings (I tried both). The 1250 (a 300+ gph pump) uses 1/2" output barb. The barbs are not interchangable on this pump (threads are different sizes on input and output), and thus the 5/8 OD tubing is the right size.... If you purchased a 1262, it looks like you we given a 1250. I'd return it if you are expecting 900+ gph...

saltyfun · 04/27/2006, 04:31 PM

I hear what you saying. Maybe I got the wrong fittings?

I got 2 - 1262's and they each came with a 3/4 and a samller 5/8"? fitting.

I call MD(thats where they came from) and ask them whats up.

crumbletop · 04/27/2006, 04:53 PM

It sounds like they sent you 2 1250's. The 1250 comes with 3/4" and 1/2" fittings. Those fittings are threaded too small to fit the 1262, so I'll bet they shipped you the wrong pump

Jack

saltyfun · 04/27/2006, 05:01 PM

No the name is printed on the back of the pumps, they are right.

I got 2 - 1262's and 1- 1260

All the treads are 3/4",suction and pressure sides.

Marine Depot had know Idea so they gave me Eheims number. I'll call in the morning as they are closed.

crumbletop · 04/27/2006, 05:20 PM

One other thing just to check, then. Are you putting the tubing _inside_ the barb or over the barb? The tubing should go over the barb.

Jack

-=DieselDave=- · 04/27/2006, 05:21 PM

The watt's is printed on the back plate 80W for the 1262 and 65w for the 1260.

"All the treads are 3/4",suction and pressure sides." Yep

trmiv · 04/27/2006, 05:29 PM

I'm using 1" on my 1260. I have a 3/4" MPT to 1" slip adapter going to 1" spa flex that naturally curves to get outside my stand, then a 1" slip to 1" threaded with a hose barb, and then 1" vinyl tubing to my tank.

Zoom · 04/27/2006, 08:52 PM

Eheim 1260-1262 it is the same size pump.

I use a 3/4" MPT to 1" insert S#80 on both ends, you need to use 3/4" mpt S#80 it has longer threads yes it is Metric but it is very close to 3/4" US MPT use some Teflon tape and you are good to go.

sjm817 · 04/27/2006, 09:05 PM

Here is the stock, sched 80 and sched 40 3/4" MPT fittings. As above, use sched 80 and some teflon tape.

saltyfun · 04/28/2006, 08:31 AM

OK, I just got off the phone with Eheim.

They said all the - NEW - 1260,1262's Have the same 3/4"(well its really metric) size thread sized fittings but,

The hose barb is different on the new pumps.

Like I said the intake takes a 1"ID and the pressure side is a 5/8"ID.

They said it does NOT change the flow rate of the pump but creates more pressure.

crumbletop · 04/28/2006, 04:19 PM

That's the same as my 1262 (it's a month old). FWIW, the ID of a barb is always going to be less than the ID of the tubing you'd use. It sounded like from your original post that you used 5/8 OD tubing. The OD of the barb is what you use to figure out what size ID tubing you need to go over the barb...

Jack

saltyfun · 04/28/2006, 04:42 PM

Yeah, I guess I wasn't clear but I thought everyones outlet excepted 1"ID tubing and I was wondering why mine was only 5/8 ID.
