SIZE of male and female quick disconnects

Anyone know the technical size for the male/female quick disconnects used on most of the penis enlargement cylinders?

I want to order some but not from any of the regular penis pump makers—theirs are twice of the price of a lot of plastic retailers on the net.

The threaded part that screws into the cyllinder is 3/8” in diameter. Make sure it comes with a rubber o-ring.

The few I have seen look like these: Page Not Found : CPC

Are they what you have in mind? I have also seen no-name "import" knock-offs of these too.

Hope I have helped.

I ordered these parts but:

Quick disconnect male fitting 5012k251 $1.42—not the same thing that VACUTECH uses

Quick disconnect female fitting with shut off valve 5012k31 $6.74—did not have an O-ring and tap size appears to be different than what VACUTECH uses

I would like to know the technical sizes for the Colder parts that VACUTECH uses?

I thought this was going to be a thread about which sex loses their temper faster. It is women.
