Fittings problems.

Unread postAuthor: ALIHISGREAT » Wed Sep 26, 2007 3:47 pm

i ordered some fittings off the internet and they arrived yesterday but in my cannon setup i have a 3/4" plain/bsp threaded barrel nipple going into a 1.5" to 3/4" reducer but the barrel nipple is wayyy too lose in the reducer so i can't use regular pvc cment to join it, does anyone know if them is another kind of glue i could use or if there is a way to fix the problem without replacing the part??

and i forgot to mention its the plain end of the nipple going into the plain reducer that is the problem not the threaded end.

It is indeed hard to read, but he explained it just fine.

He has a 3/4 "barrel nipple" (whatever that is) I'm assuming. BSP/Slip. He also has a 3/4" x 1 1/2" bushing I'm hoping (and not a bell reducer which is DWV) and that is slip/slip.

He is trying to connect the slip part of the "barrel nipple" to the 3/4" side of the bushing and the tolerances are off so it's a loose fit.

My advice to you would be to return the faulty fitting and get a new one, instead of "Afro-Engineering" it to work.

Right, your brand new and are giving people crap because you can't comprehend what he said.

I suggest you use JB Weld, or an epoxy equivalent.
be sure to lightly sand both surfaces/

Where did you order the parts from? If you are dealing with a reputable dealer or website, I would return the fittings for new ones. There is a range of sizes that is represented by one nominal size.

You could try the jb weld or plumbers putty, but you would get a stronger joint by returning the parts for better fitting ones. If you ordered from a plumbing specialty shop or something like McMaster you shouldn't even have to pay for shipping for the return and stuff.
