The threads on what I can find aren't deep enough. Thanks. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Jerry A, I'm not really sure if 57 still used the "threaded sleeve" setup that was used on older models, the p/n for the nut for 1/8" tube is 6100X2 which is a Weatherhead number, hope that helps. | | | | | Joined: Apr 2004 Posts: 375 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2004 Posts: 375 | Thanks. It's male and it's compression style. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Jerry A, if it's compression here are the Weatherhead p/ns for the compression sleeve and the nut for the line, you didn't tell us what size tubing so here are a few numbers
compression sleeve nut
1/8" 60X2 61X2
3/16" 60X3 61X3
1/4" 60X4 61X4
I'm sure you get the idea, hope that helps. | | | | | Joined: Apr 2004 Posts: 375 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2004 Posts: 375 | I'd bet it's 1/8" (very fine). I ordered a pair of 6100x2's from Aircraft Spruce today for $.44 each. They'll ship on Monday. Thanks again.
I checked the dimensions of the ones I ordered vs. what I took out and found that the thread went a bit deeper on the new part. That should solve the problem I had with the old one. | | |
