Question Best way to clean a DIN 1 stage without getting water inside

[iointerrupt]

No doubt, from salt water. But from fresh water, that got past the dust cap, while rinising?

Some one remind me to check on these in a month:



The Mk2 went in with an IP of 142psi, and the 2950 went in with 168psi.

This discussion happens every time someone talks about rinsing first stages. I'll only say that lots of divers and lots of dive shops have collectively soaked their dust capped first stage millions of times without a problem. We've even been know to push the purge button on the seconds (gasp) as long as the first is held above the rinse water.

OTOH, there will always be people to tell you not to do it and they'll often supply pictures of corroded regs. Although somehow the outside of the regs are always a mess too which is not what you'd get from well-rinsed regs.

There's also the fact that you need to soak regs to really get rid of all the salt crystals. Rinsing is fine to clear the sand and get you to the next day's dive, but clean means a soak. Cenote/spring divers are excused here.

IMO, pressurizing the first stage only protects you from boneheaded moves likes soaking without the dust cap being in place. But if you can't concentrate enough to rinse a reg safely, adding pressurized gas to the mix changes a potential headache to a potential catastrophe.

Scubapro dust caps are just dust caps, if you want to soak it unpressurized get a screw on cap that properly engages the DIN o ring.

This ^^^^ The standard "Push-ON" DIN caps that come with the regulator are crap. They don't seal at all.

No sé qué es el bloqueo hidráulico, pero la corrosión dentro del regulador debido a la entrada de agua es algo real.

La mayoria de las veces, cuando tenemos corrosion dentro de las las primeras etapas, ( eso ocurre en todas), es debido al aire que suministra en compresor de carga, a los compresores y sus sistemas de decantacion y separacion de agua le cuesta mucho entregar aire 100 por 100 seco, por lo cual al cabo del tiempo y el uso, los reculadores presentan corrosion y depositos calcareos.

If you find a discarded sinter filter at the local dive shop you can try a small experiment. Fill it with water and it will hold it like a cup of tea without dripping any down through the other side. That sinter filter installed at the entry point or inlet in a 1st stage (whether Yoke or Din) is designed to let only pressurised air pass through.
So even if some water does leak into the inlet through the dust cap while it is soaking in a tub, it’s not going to pass through into the regulator innards.

This is only partially true.
Water won’t pass through it IMMEDIATELY, but it’s only a matter of time.
Do the experiment, grab a yoke retainer with the filter and star clip assembly, fill with water and let it sit over a piece of paper, all the water will sip through. Wether it passes through the filter or around it, I’m not sure, didn’t care to know the difference really as it wouldn’t matter. It’ll hold water for some time, I don’t remember how long it took, but once it passes through, all of it goes through, meaning that it isn’t a slow process, nothing will pass through for some time, but once it starts, then all of it passes quickly.

Well?????????

Well?????????

Not a drop into the regulator: Rubber DIN Dust Caps: Leaky Nightmare, or Master Sealer?
