Is there a source for new engine end oil line fittings ?

CycleX makes them I think.

More like adapters than replacements though.

They have 'replacements' that aren't as internally large, gimmicky IMO. If your hoses leak just get a set from one of us members, they rarely leak. I use black spray paint to freshen the fabric cover so they don't look dingy and gray anymore. Others use fabric dye but that is overkill IMO and doesn't work all that great anyway

Was looking to make my own out of copper or something to go on the sacrilegious Rat Racer  I'm workin on.

Probably not a great idea because it will most likely crack in a short amount of time from vibration. Gonna have to be function before form in this case

If you need oil lines, I have a spare set of stock ones

Thanks!!! I have plenty. Just doin something different with this one. I see stainless lines and wonder how they're made if someone isn't making new factory type fittings.

I make my own from SS hose, reusing original fittings.

The threads at the tank are M22 and M24?  Not that easy and common to find tooling for that.

Really!! Do you have thread in tip n tricks or anything like that? How to take apart without damage and reusing. I'd like to see that!!!

When assembling the Amen and other chopper frames, we cut off the fabricpart, then welded on an AN fitting.... A -6 or -8.=

[bjbuchanan]

The stainless is a sleeve, stainless braided, not solid like copper lines...

Grind off the crimped portion and it has a barbed fitting then use rubber hose.

I use hacksaw to cut through the crimped ferrule.  Hoses from hydraulic shop - the pressure is very small, but the hose needs to be able to handle hot oil - and ferrules from McMaster Carr:

The crimp easiest is to find a shop that will crimp it for you.  Only one of the hoses needs to be indexed - i.e. ends have to be in certain position against each other.

My house doesn't roll around much with a hard mounted engine so I can't compare notes but I still think it is a lousy idea.

Bikes with this kinda stuff on it usually don't get ridden anyway so it shouldn't matter in the end huh

He could adapt these hoses:



 

For some reason I think the rigid copper tubing would do just fine as oil lines; I used copper for air distribution in my shop and it is holding up well even the connection to the compressor.

But it would be a pain to install.

Edit:  I just remembered, the oil pressure gauge in my jeep is hard connected to the engine by copper tube.  I installed it many years ago, because it is more reliable than electrical pressure sensor and electrical gauge. The tube goes from engine to the dash and as I said it works without issues for 15 years now.

Nonferrous metals do work harden. If annealed it would work fine on a motorcycle or car. As for riding hope that wasn't aimed my way.

I've seen lots of examples of copper being used for oil lines. Wrenchmonkees have used it on a few of their builds.

So nobody makes replacement fittings ?? Seems there would be a market. So many after market parts for these bikes I m a little surprised
