Carrier 1800 receiver rotalock fitting

[niko0807]

Hi All,

I have a carrier 1800 receiver p/n 65-000181-02.

I looking for a suitable rotalock to solder fitting, but I just can't the right one.

According to the manual it should be a "1/2" Nut & Sleeve", but the thread measures 20.3mm OD.

I've taken a few photos and really hope you can help.

1/2" nut, the expression is probably for 1/2" pipe.
