hi everyone ....
out on site right now and it appears most of our hats .. KM 77 and KMB 28 are set up with NPT / 02 fittings
as there main umbilical connection. I and others believe it should JIC / NPT instead but the exploded parts
break down only lists the part as an "adapter" ... just curious if anyone else has seen this or knows of a change that I am unaware of.
This is a common problem. Both work just fine. The issue is that the ignorant will mount a hat up that has and o2 male to a JIC 6 female hose. The threads will fit, but the no seal is made.
Learn your fittings. Inspect them every time you make a coupling.
thanks guys .. I know either can work , but was curious more towards which part is typically sent from KM themselves as I mentioned it is only labelled as an 'adapter'.
Thanks for the information .
When I bought my 57 (new) 4 years ago it came with and O2 male fitting. I keep a JIC 6 in my haat bag just incase I end up freelancing with a company that uses such. O2 seems to be the most popular amongst dive companies.
