Camlock gender convention?

[julianf]

Im sure i asked this once before, but cant find the post -

Is there some sort of convention in industry as to gender of camlock fittings?

For example -

Do all hoses use, say, male?
Is male the direction of flow?

etc?

I thought id probably use female on the pumps (as theyre the more expensive fittings) and male on the hoses - unless someone tells me otherwise?

The only fittings of those types I've used are on tractors and diggers.Generally, the female is connected to the machine, while the male is connected to the attachment, on the end of the pipe, so your picking up the male, and shoving it into the bolted down female. In fact, I can't think of anything I've used which is the other way.
It's not really the flow, because the oil flows both ways in those pipes. I guess it's more the fact that the male end is lighter, with less moving parts, and if it gets dropped in the dirt, it's easier to clean.
I'll avoid making jokes about how it's just more natural to pick up the male end and ram it in the female......

Edit: As you say, it could be about price too. The female is more complex, so it stays with the pump/ machine, then the cheaper male can be fitted to a variety of attachments.

Also if you have multiple potential connections you can, with some planning, arrange things to exclude the possibility of making a connection that could cause a problem.
e.g. connecting a veg oil line to your bio storage tank (extreme example, but you get the idea)
