Hmm, maybe my 1262 came with a different adapter, because it fits perfectly into the 1" spa-flex I use.

Those dimensions are for I.D. hose.
Spaflex and such are measured by the O.D. of the rigid PVC used, so not a good match.

Easy, use a section of vinyl hose from the barb on the pump to a Spigot-Slip adapter like these:

The vinyl hose is a good idea anyway as it helps to isolate the pump's vibrations from the rest of the plumbing.

Agreed, but it's nicer to use spaflex as there is no need for hose clamps

For 1262's you can use a 3/4 male to female PVC piece . I then use a link of 3/4 spa flex to get rid of any vibration despite there being pretty much none.

thanks for all the feedback. I just ordered a bunch of 3/4" and 1" spa-flex so hopefully it should be here this afternoon and I can continue with the plumbing.

Nate, the slip - threaded reducer you are talking about bottoms out in the pump well before it starts to tighten up. The short nipple I linked does tighten some so I feel would be a better seal.

Use Teflon tape or cut off some threads works just fine on my last 5 installs of 1262's

Where did you order the spa-flex from?
