P valve hose size

[ScubaShagy]

Im building my own p-valve. I’m having issues finding what the hose dimensions are, and the measurement of the male to male (hose to condom) fitting. Does anyone have this information?

I think 1/4” is the barbed fitting size.

Here’s what I used. Comes with a nifty adapter for rinsing the valve. Can’t beat the price.

Some sizes need building.

Are both sides the same diameter?

The barbed end is the side that goes into the condom correct? Does the smaller hose cause a restriction when relieving yourself? I would think the hose should be the same size as the end that fits into the condom.

the smaller size goes into the condom for that one.

1/4" seems to be the standard size in the US though some use 3/8", doesn't really matter. I use 3/8" and 3/8" barbs on everything though it makes the condoms a PITA to get off at the end of the day. Europe uses 1/8" for some reason. Your urethra is ~1/4" so no need to go any bigger.

For the hose, use 1/4" or 3/8" Norprene hose
For the quick disconnects, I use Colder PLCD series acetal shutoffs which are what the manufacturers sell.
I use female on the suit side, and male on the cath. I use shutoffs on both sides and carry a spare female straight thru so I can go topside since some urine seems to stay in the condom after you disconnect. Most use a straight-thru on the condom side, and a shutoff on the suit though. Advantage of the shutoff on the suit though is that you don't need the ability to shut the p-valve off when not plugged in

Re Norprene, you can also use gas line (in a pinch) which is available everywhere, Lowes etc.
