Has anyone used this swagelok hoses ???

Philippe GERIN

I don't know about these ones, but the ones from Subaqua (http://www.subaqua-products.co.uk/products.htm) will definitly work with the Swagelok PB-4 hoses. Both ends work: 3/8 unf and 9/16 unf.

BSR-Aerotek sell a good range of UNF to BSP/NPT adapters and hose tails with online ordering. They're a motorbike parts company in the UK.

I've got these hoses on the O2 side of my CK. They work fine, and are a lot easier to deal with when screwing regs into tanks, unlike the braided SS hoses a KISS comes with.

Cut them to the right length (get the missus to check up on your measuring abilities), clean 'em and Bob's your uncle.

That's what I'm looking to do as well. Would you have the part numbers readily available that I'd need? It would be much appreciated.

Paul, as long as you're in the US. Here you go:
3/8-24 unf reusable: Oxycheq or M&J Engineering (Hose repair kit) part#HPK-1000-4
link: http://216.234.178.228/shop/index.ph...9b2dd197b4a6da
Swagelok push-on fittings: You'll need 3 of them.
Link: http://www.swagelok.com/search/find_...TA4&PG=0&RPR=5
Hose: PB-4 is the blue. That's the one they usually have in stock.
PB-4-BK is black; -GR is green and -RD is red. Get about 20ft of it and you'll have spare LP hose handy anytime together with the reusable fittings.
link: http://www.swagelok.com/search/find_...B-4&PG=0&RPR=5

If you add M&J part ADT-2002B to the manifold and one Hose repair kit part#HPK-1000-4 you'll be able to replace the braided hose on the dil side too.
Part ADT-2002B link: http://216.234.178.228/shop/index.ph...3c5cc4299711e7

You can also do this with a BC hose and a BC quick-connect fitted to the manifold: http://216.234.178.228/shop/index.ph...3c5cc4299711e7

Hope this is complete and helpfull

Excellent, thank you.

OK, maybe I'm not quite getting the whole Swagelock thing. I get how the hose connects to the fitting but how does the other end connect to the KISS? Being at work right now and not being able to put my hands on the Rebreather maybe is making it difficult to visualize. There are no threads of any kind on the end that will be sticking out of the hose...

Philippe GERIN

It's because it's a tube fitting and yes, I forgot to mention that you need to get the nuts and ferrules separately because the one you have will stay on the braided hose.
nut: SS-402-1
front ferrule: SS-403-1
Back ferrule: SS-404-1
You need one nut+one back ferrule + one front ferrule per tube fitting.
They usually sell the back and front ferrules by 10 "on a stick".
Nuts can be bought by the unit.
If you cannot put that together, PM me. I might be able to help with a few spares that I have in my drawers.

Thanks Philippe I've already got an account set up with my local Swagelock distributor so I'll just add those to my order. This is the first I'll be messing with Swagelock fittings so still trying to work it all through in my head, the lack of nuts/ferrules had me a bit baffled as I didn't think they came off the fittings on my KISS but, not having it to look at I couldn't say for sure.

Thanks again. I think I should be set.

In a word yes we have tested this type of hose IMHO I don’t think this is a good choice for oxygen there is a much better option with the SAE 100 R7 and stainless crimped ends. Using nitrile is the poorest option, Swagelok were well advised to suggest changing the hose each year. In oxygen nitrile is a pretty poor material and will age quickly become brittle and crack.

Also consider that push on fitting are not allowed in divers breathing hoses offshore or with military as not an effective closure for critical use. Re-useable type fittings for commercial divers umbilical and bail out whips were banned some 20 years ago.

The other consideration for breathing hose is the fitting pull test (push ons failed this) and a tension test were a sample hose is loaded with a 50Kg weight over a 2 inch tube for 24 hours, the hose is then tested for elongation and deflection by length measurement and by shooting a steel ball through the hose. If it passes this the sample is then subjected to a hydraulic burst test within 12 hours. Agreed not all “divers” equipment is tested to this standard showing once again the difference between standards for Diving and Scuba. Iain Middlebrook
