I've never used a flare tool before.

Or is this a special order item? | | | | | Joined: Feb 2004 Posts: 29,796 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,796 | The nut itself is the compression fitting. It has a thin tapered front section that bites into the tubing and seals the first time it's tightened. Once the nut attaches itself to the tubing, it is supposed to stay there during later removal/replacement of the tubing in the oil connector. If the nut is installed properly the first time, about 1/8" of the tube or a little more protrudes past the front of the nut, then the tapered portion of the nut crimps itself to the tube as it's tightened..
Every local parts store used to stock those nuts, but that was 50-something years ago when these engines were daily drivers. Someone posted a reference with a part number recently but it was for a 1/4" OD tubing fitting, not the 3/16" OD one that fits the oil connector line.

The copper tube through the water jacket that goes up to the oil connector on the spray-oilers uses one of these nuts to crimp down on the tube and prevent coolant leakage into the pushrod chamber. There's a mating female adapter that works with the male thread to provide the crimping action as the nut is tightened. I believe this is the female thread adapter that works with it: http://images.oreillyauto.com/parts/img/large/ede/orly_265301.jpg The early-style oil connector with the line that threads into it has a similar female thread to provide the crimp the first time the fitting is tightened onto the oil line.

What will happen if I try to re-use the nut? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Feb 2004 Posts: 29,796 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,796 | Very good info, Tim! Bookmarked!
I have re-used a nut on occasion, but the crimp doesn't work well on the second try. Ford Flathead V8's used that type of fitting on the fuel pump to carburetor line, and reusing a nut could produce a gas leak, occasionally.

They also had the tubing, but if WalMart can get it (for $16 shipped) . . . | | | | | Joined: Feb 2004 Posts: 29,796 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,796 | With a couple of those nuts and the copper line, the through-the-block oil line on a spray-oiler engine can be fabricated for a lot less than the cost of the kits the resto-parts people sell. The female fitting that goes into the block usually doesn't have to be replaced.

This was not in stock, so instead of bringing in one single nut I ordered ten. So now I have a lifetime supply of oil connector fittings! | | |
