There is an existing Sched 40: 3/4 inch condensation line from my A/C that I need to connect to a bath sink tailpiece. This is how it was connected previously and I checked code and it's cool (a/c pun). I've been remodeling the whole bath and of course I threw away the old connections so I'm not sure what fittings they used. So, my problem is connecting the Sched 40: 3/4 inch PVC to a dishwasher hose with 7/8 ID. I cannot for the life of me find a 3/4 PVC fitting that has a 7/8 inch barb for the dishwasher hose. I can't find a barb of that kind on anything other than on a tailpipe or garbage disposal. Any ideas on how to connect 7/8 dishwasher hose to 3/4 PVC?

the connection to the 3/4 pvc does not need to be barbed.
there is no pressure involved here.
any rubber or vinyl hose that will fit over 3/4 pvc and tightened with a good quality stainless hose clamp will never leak.
then the hose may fit loosely onto the barbed tailpiece end but should snug right down with a hose clamp.
remember the key words here are 'no pressure'.

Have you tried heating the hose and see if it will stretch over the pvc? You could transition the pvc to 3/4 copper and the 7/8 will clamp to the copper with no problem.

yeah, there is one european DW out there that comes with its own proprietary hose that doesn't fit any of our barbs.
you need to eat a can of spinach for lunch to push the hose onto something.
BTW, here is a dishwasher tailpiece with no barbs.
they are common and used all the time. never have a problem.

I greatly appreciate all of you taking the time to answer my post. The answer that helped put this baby to bed? 3/4 inch Copper Pipe has the right diameter for the 7/8 ID of the Dishwasher hose. Also, the reminder that this is not under pressure. Thank you again all!

so then you want a 3/4 inch pvc female adapter and a 3/4 copper male x street adapter.
no soldering necessary.
note... the copper end of the adapter is size of the tubing. 7/8 OD.
