Scuba Pro MK 25 First Stage Question

Turret up typical hose routing. If there is a wider gap between the four on the turret that usually goes towards the diver:

To add to the photo above, my preference FWIW:

Hogarthian: Long hose primary (blue in photo) and secondary on a short hose (yellow in photo).

Conventional: Primary on short hose (yellow in photo) and octopus on long hose (blue in photo).

orings torn and FLAT

Stock standard condition of orings coming out of some correctly torqued-tightened firsts on hoses

I would also add shredded, is the nature of the beast

Well I have searched on and off over many months now - and will you believe it? Nothing for $10 in my country with a slim jaw! The 4” slim jaw adjustable wrenches I can buy online are all above $40 - add $20 shipping and $30 customs duty. Now thats a $90 expense to use a tool for just 10 mins per dive trip to make things just a little more snug than finger tight!

Try a bicycle repair shop and ask for "cone wrenches".

I generally prefer turret up on a Mark 5/10/20/25 but with some occasional exceptions I may run it down.

Swapping hoses to the correct ports is awfully easy. Just do not use pliers please. Use a proper wrench. Hoses do not need to be tight, just beyond finger tight. The ongoing discussion of to lube or not to lube hose end O-rings is mostly esoteric as it really does not matter. Static O-rings, such as these are, generally do not require lubricant but whatever.

I will probably be told again, like I was with the fellow who had a very slight leak in his regulator second stage to adjust the orifice, that I would probably cause your/his death to which my reply is whatever. Nobody lasts forever and safety is way overrated IMO.
