Return fittings

Anyone familial with these fittings?

My question is just if the 1/2" ratings on these are the same for 1/2 pvc fittings?

 

nope totally different! they are nothing more than cimcool fittings use for milling machines and lathes the 1/2 - 3/4 and so on is based on their own class

 

"K" is the one you want to begin off of the internaly threaded bulkhead (if you have that)

you begin with that and continue on flares,ends,ball socket/s ( to entend the length )
they "pop" apart ,add as needed to fit your requirements .

to my knowledge they are the same thread as run of the mill "pipe threading"

what is your application ?

 

The 3/4 is a little over 1/2 I.D the 1/2 is like 5/15 I.D but that will increase the flows pressure .. If you use them don't buy the pliers worthless and not needed its will snap right together and apart . A slight smear of light oil I use Vaseline in and on the ball and socket will make then slip together and less cracking . They all have a Standard NPT on the male adaptors

 

Have four returns to my tank but they are hard plumbed with 1/2" PVC. Plan on buying one of Oceans Motions devices and hooking it up. Just need to find a way to direct the flow.

As always a thanks to everyone who responded.

 

This is what I got. It comes in black too.
