MK25UK - DIN conversion kit

[alexrib]

Hi,
i have recently acquired a MK25UL regulator (INT configuration)
is it possible to find a DIN conversion kit for this item?

Alex Haven't heard of a MK25 UL, probably you are writing about a MK20 UL. Anyway, SP offers only a universal DIN Conversion Kit,# 10.045.030 that works for all actual models and the old ones as I see it.

Tnx for your replay but I actually mean
Mk25ul. It was limited edition of this regulator manufactured and it was made of materials similar to mk20ul. Therefore I'm not convinced that standard conversion kit is suitable
Tnx

I see no reason the Scubapro universal Din connector wouldn't work fine. You could also probably use a MK18UL or MK20UL DIN connector if you could find one, but you'll probably find that they are near identical to the universal connector.

You better ask Scubapro.

The UL is made of anodized aluminum and is known to corrode easily. The part number for the DIN retainer of the Mk20UL is 10.715.123, whereas the one for the straight Mk20 is 10.400.126, same as the Mk25. They may be made of different material.

The torque spec is the same for the MK25, MK25TA and the MK20UL. That makes me think its unlikely they used an aluminum alloy. I see that the part number for the MK25TA DIN retainer is 10 760 123, it's possible the UL regulators use a titanium alloy DIN retainer. I don't know if titanium is more or less likely to have a corrosive reaction with aluminum than brass or stainless steel but would be interested to know.

Wikipedia has a good chart that shows the galvanic compatibility of different metals. I think titanium is out of the question because there is to much difference in the Anodic indexs of aluminum and titanium. If the MK25UL's DIN retainer is not made of an aluminum alloy the best alternative appears to be chrome plated brass.
