Oil cooler fittings

This is for Gaz, who's putting an oil cooler in and he's not familiar with fitting types....

(I can't figure out how to attach to a PM)...

What prompted my question to Carolyn was there's a bit of snow under the car & I wanted an opinion from someone who 'could draw the oil fiter housing blindfolded' sort of thing. The sandwich plate I'm buying has the hose connections pointing downwards.... looks approx 30 degrees off vertical. I'm going to use a connector that the hose pushes onto & a jubilee clip, rather than the type Carolyn's pictured.
They are cheaper from China (as was the sandwich) so I wondered if I should get a straight connector like

or would an angled one of some kind be better just for the ergonomics of fitting. I am thinking of locating the cooler at the bottom of the bulkhead, but won't decide until I physically try it.

I'd trial fit everything and then decide on the fitting. Get the best result that way.

Can you imagine building this any other way?:

Gulp!

Only way to do it as Carolyn says.
I worked in a drawing office, in the days before CAD. A part of what my Company produced were hydraulic power units. The major elements were relatively straight forward to position and detail supports in 2D but the interconnecting pipe work was a nightmare and so this was done on the job and a record drawing produced for future reference and repeatability. I guess it would be easier now with 3D systems and a bucket load of pre detailed drawing elements.
Tthe pressures in car lubricating and cooling systems are lower than in a hydraulic power unit so the "hose bib" connection your looking at could suit your situation, maybe @Carolyn has experience of this.

I see one big flaw with this design, where does the keg of beer go .... :withstupid:

Yep at 100 psi, good quality hose clamps will suffice. Hydraulics tend to run at up to 3,000 psi and my rocket systems from 1,000 to 2500 (depending on what part of the system). Crimp connectors are then a must.

I think you'll find you want angled fittings. The hose isn't very flexible.
At China Inc prices, just buy 60 deg angle fittings for your trial fitting and don't worry much if it doesn't work out.

Gaz mr-s · January 31, 2019, 18:46

Jonbill what angle do your oil connection come out of the sandwich at, & where did you locate your cooler?

I think you'll find that's a picture of his Datsun!!

I'll say it again, offer the parts up loosely and see where they fit best.... it really is the easiest way. You can't pre-judge this. Of course, you will want some air-flow over the cooler. Take your time, 'cos it's not going to be 'obvious'.

I realised it wasn't a 2... "what's the mess....." Lol

If I order from China then I need to order soon....yes there's some impatience involved....

Cooler location idea may not work....I won't know 'til I try, but I thought it'd be easy to recommend the best sandwich exit angle.

Carolyn · January 31, 2019, 19:20

I'd go with Jon's recommendation of 60 degrees... 60 plus 30 = 90, so it should get the hoses tucked in somewhat.

jonbill · January 31, 2019, 20:17

That's not mess, that's patina.

By all means use the China Inc Fittings for mock up, but I wouldn't trust them for long term use
