Has anyone replaced the DIL manifold feed?

Dave Crampton

The hose which feeds the manifold on my CK051 has about 5 different swaglock (sp?) connections from the 1st stage to the braded hose which then routes up the inside of the case past the DIL CL to the manifold (older O2 on LHS model). I'd like to remove this hose as its only an IP feed and put a rubber one in its place. removing a number of connections with 2 or 3.

Does anyone know what type of hose I need to go from the Apex 1st Stage to the inlet of the Manofold. I'm also thinking I perhaps need an elbow to interface between the hose and the manifold to accomodate the sharp right angle.

Cheers, Dave C

Dave; Why not get rid of the manifold entirely? I run one LP hose from the DIL first stage to the ADV. I run a second LP hose to a splitter and then to my BOV and wing inflator.
I run the hoses up through the CL case. If you do that you may need larger CL's as some space within the case is used by the hoses.
Makes getting the CL in place a bit tougher though.

I think I saw your Y splitter in a previous post. Looks good. Supplies by MJ engineering isn't it? I might look into this.

I do like the idea of keeping the manifold though as it has a spare port at the moment which I can use to add external DIL from. I'd plan to use a quick conection so I could pass off the cylinder if diving from a RHIB. I think I'd need one way flow valves to stop the two cylinders from trying to equalise through the manifold though if they were both accidentally turned on at the same time - although they are fed at IP so I'm not sure if that would be a problem.

I'd like to get a way to add external DIL to the whole lot soI can still use the DSV / BOV , wing and suit feed though off the manifold.

IIRC the braided hose into the manifold uses one of two tapered swagelock'esque compatibile ports on original Jetsam manifold. (Don't quote me on that though) I think its one end and the last one on one side... if you catch my drift.

If you swap that out for a rubber hose (which you can do and several people have) then you need another tapered blanking plug and to use another port in the manifold. Several people who've done this have swapped the manifold out for a 3rd party effort with all "normal" ports.

Depending on the type of 1st stage you have and the size tanks your using it is also possible to run the hoses up the outside of the case between tank and scrubber. If you decide to reroute the hoses in this section then you leave yourself with alot of test fitting and fettling/faffing to do, but once sorted it can be really neat.

You can get suitable hoses, hose and fittings as well if you wanna make your own from AP spares, a 1st stage to dil hose from an Inspiration would work fine, you may even need to shorten it slightly.

PS- I'm toying with either doing away with it or reducing its use considerably, think running the BOV off inboard tanks might be abit restrictive... only leaves ADV and wing, can do that with a splitter... anyway, future plans

I went down this route with the SK, see- http://www.rebreatherworld.com/class...html#post49579

Not sure it was so well thought out in hindsight....... (see the comments)

All you need to add offboard dil is a BOV fed from offboard.

You need to have the- "how many eggs in one basket debate" with yourself!

If you run everything through a manifold and it or any of the many hoses has a problem, you have a problem. Running just wing and ADV is minimalist but reduced the failure points to a minimum (if you believe that'll make a difference)

BOV should (many might say) be fed from the larger offboard tank, mix chosen for the depth obviously and the suit fed from a suit bottle or offboard as well (the suit being pluggable by design anyway, you can swap with the wing feed if required, so long as your suit and wing feeds match ala DIR )

Therefore you have-
Dual/redundant DIL feed- ADV and BOV (open breath in, close breath out into loop etc)
Dual/redundant Suit and Wing feeds (each other but from two sources)
Voluminous BOV supply- offboard pluggable/handoffable tank

...and if you make sure your buddies have a feed hose (you could buy a spare and ask them to add it if you don't have a regular buddy) then you can steal BOV gas/dil from them.

Erm, Yes.... I think that was roughly the plan I eventually came too.... might not be brilliant but it was all about minimising hoses and risk, may still need some refining, see what you can do!!!

Not sure that I'd really want to do this with the Paragon regulator. Sure it works but, for me, just for enough time to have a think and go on to something else.
Dave - a few of us have replaced the manifold with one that uses all 3/8"UNF fittings made by a friend of a friend. Let me know if you'd like more details.

Dave Crampton

I've pm'd you my details for you to get in touch.

Ben Field

Agreed, but then I don't consider the Paragon equipped BOV as a BOV, its more a PITABOV I have a Mares on order, will see how that performs.

However, conceptually- should you have a decent BOV running it offboard from a reasonable sized tank is still IMVHO preferable.

A couple of KISS guys here upgraded, and it is a lot nicer in real life than in the picture... I believe you will enjoy it.

I saw this at last years Brum Show. It looks great. How much doe it cost? I don't see it on the parts list yet.
