ScubaPro MK2/DIN leak problem

[fmerkel]

I'm in the same boat as rhwestfall. Don't have access to my stuff right now. When you remove the fitting and look in the body of the reg is there a small hole of to the side of the main hole?

Yes. Mentioned that in the original post. It clearly feeds tank pressure to the HP port. It's right on the edge. From there the main hole tapers down in a very shallow funnel shape. It is NOT FLAT like the other reg bodies I'm used to.

You have the wrong o-ring. It needs to be sealed on the exterior of the DIN fitting. There should be no oring on the bottom

That adapter works however you use the white o-ring around the body to seal and not the yellow one.

I don't have SP color O-rings to reference. Do you mean to use the [white one] in the main body groove to do the sealing? That's what I have done and it seems to be working.

Yes as that's how the MK2 is sealed.

Yep, that's what I've done. Should this be 90 hardness (poly maybe?) since it's sealing tank pressure?
I still DO put in the bottom 011 O-ring, right?

Remove the one on the bottom as it can block the SPG port.

 

[Timmy V]

Yes 90 duro is fine but make sure to remove the bottom one.

Part number is 010 501 158. Is it possible you had debris on it such as a piece of hair? Is there a knick in the sealing surfaces?

No nicks, no hair.
I just used an O-ring that would appear to fit and it worked. Looks to be an 015. The SP references are anything but helpful.
Laying the bottom O-ring in the body cavity it doesn't look like it could seal off the HP hole.

I'll leave it to you but I am a SP tech and there is not suppose to be an o-ring on the bottom.
