1" Strainers don't fit 1" pipe

So my 1" strainers don't fit my 1" standpipe. Am I supposed ot use 1/ 1/4 coupling. I'm a bit lost. I tried test fitting the strainer with a 3/4" pipe inside it, but that wasn't a snug fit. I'm talking about these.

well that sounds odd. I wonder if someone shipped you the wrong item.

I've never used those before. Are they the same diameter as your 1" pipes? If so, I'd say a coupling would work.

Here is a picture. What size coupling would it be. 1" or the next size up. I guess i'll take a drive over to Lowes to see what matches.
 

You just need a 1" coupling.

It looks like the outside diameter of the strainer is exactly the same as the outside diameter of the pipe.  Is that true?  If so, then you would need 1" couplers (Schedule 40, just like the pipe).

You just need a 1" coupling.
 

Got it. Lowes had a pack of 10. Test fit it in the store.... why do i always feel weird bringing plumbing parts to lowes in my pockets... then I have to put them in my pocket so I don't pay for them..I always feel like someone is going to think I'm stealing them.

Hahaha...put them in a bag from a different store.  That's what I do.

The 3/4" strainers will fit in the 1" pipe.  That is what I use out in the clownhouse.
