[PSUBS-MAILIST] HP air whip

[Jon Wallace via Personal_Submersibles]

 Thanks for the response James.  I found a USA supplier at Dive Gear Express that custom make them as well.  I am still pondering whether to bring HP into the hull or put first stage balanced regulators on the tanks and bring in 150psi (or there abouts).  I'm not bothered by HP inside the vessel but LP plumbing parts such as manifolds, pipe fittings, and valves are going to be significantly cheaper and more highly available.  I'm not sure there's a real winning strategy over the other either way, but if someone wants to try to convince me I'm listening.

 HI Jon
https://undersea-centre.com/

This is a UK company, but they are really good.  Give them a call and tell them what you are trying to do and they will be able to advise.
They made up a pressure reducing manifold for me.  I have 2x scuba whips with male din connections both ends.  The 2 hoses plug in and via a regulator, are then plumbed into 6mm 300bar swagelok pipe.  I will do the same on my new boat, except i probably wont bother with the regulator as i dont really think its required.  Will probably just go full HP all round.
Kind Regards
James

Where's a good source for HP whip to connect external SCUBA tank to my 1/4 npt hull penetrator?  Are you guys using chrome SCUBA whips or hydraulic hose with SS connections?
