Description

Created this adapter to blow out our pool's clogged in-floor leaf canister line which has a 2 ½" female threaded connection.  Was able to hook up a blower that had the standard 1 ½" pressure fitted hose connection and it worked great.  Saved us a $350 service call.

Hi, do you have a version with the 1-inch threaded part as well?

2 1/2" male threaded to 1" male threaded or what were you needing? Don't think I have anything like that modeled already but might be able to take a look if you confirm both ends.

Hi, 2" male thread to 1" male thread. I need one that is as strong as possible to withstand water pressure.

Hello, Just uploaded it to the download section. Give it a try and let me know if it'll work for your needs. Not sure how strong it''ll be but use a stronger/more durable filament and keep a high number of walls and infill.

I created this but not sure if it'll work for your needs. 1 1/2" threaded to a dual pressure fitted choice (1 1/2" or 2"). This way I could use it either with a blower hose of my shop vac. I never got around to printing it though as my other solution worked. I made it long because it connected at the bottom of my skimmer. Let me know and I can post it in the raw download section.

I created 1 1/2" to 1 1/2" and uploaded it and the dual option to the file section. Let me know if these work for you.

Wouldn't let me upload a Fusion file for some reason but added 3mf and step files. Hopefully those will work for your needs.

@user_1472621541 , I just uploaded a step file for the 1 1/2" to 1" model you wanted. It is under this model so just navigate to the "Download STL/CAD files" section.
