Abstract
Official abstract text for this publication.
A tube connector comprising a male portion having a male portion thread on an outer surface, a first tube having a first tube surface disposed at a seat angle (θ) of approximately 37° to a tube connector centerline, the male portion having a clearance engagement with the first tube, a nut having a clearance engagement with a second tube, the nut engagable with the male portion thread, the second tube having a second tube surface disposed at a seat angle (θ′) in the range of (θ′)=(θ+x)°, were x=+0° up to 1°, and the first tube surface compressed by the nut and the male portion against the second tube surface for a sealing engagement between the first tube surface and the second tube surface.
First claim
Opening claim text (preview).
We claim: 1. A tube connector comprising: a male portion ( 10 ) having a male portion thread ( 11 ) on an outer surface; a first tube ( 30 ) having a first tube surface ( 32 ) disposed at a seat angle (θ) of approximately 37° to a tube connector centerline (A-A); the male portion having a clearance engagement with the first tube; a nut ( 20 ) having a clearance engagement with a second tube ( 40 ), the nut engagable with the male portion thread; the second tube having a second tube surface ( 41 ) disposed at a seat angle in the range of (θ+x)°, where x is 1°; and the first tube surface compressed by the nut and the male portion against the second tube surface for a sealing engagement between the first tube surface and the second tube surface. 2. The tube connector and in claim 1 , wherein the male portion further comprises a male portion shoulder having an angle (φ) in the range of approximately 30° to 50°. 3. The tube connector as in claim 1 , wherein the nut further comprises a nut shoulder for engaging the second tube. 4. The tube connector as in claim 1 , wherein the male portion comprises a hex portion for engaging a wrench. 5. A tube connector comprising: a male portion ( 10 ) having a male portion thread ( 11 ) on an outer surface; a first tube ( 30 ) having a first tube surface ( 32 ) disposed at a seat angle (θ) of approximately 45° to a tube connector centerline (A-A); the male portion having a clearance engagement with the first tube; a nut ( 20 ) having a clearance engagement with a second tube ( 40 ), the nut engagable with the male portion thread; the second tube having a second tube surface ( 41 ) disposed at a seat angle in the range of (θ+x)°, where x is 1°; and the first tube surface compressed by the nut and the male portion against the second tube surface for a sealing engagement between the first tube surface and the second tube surface. 6. The tube connector and in claim 5 , wherein the male portion further comprises a male portion shoulder having an angle (φ) in the range of approximately 30° to 50°. 7. The tube connector as in claim 5 , wherein the nut further comprises a nut shoulder for engaging the second tube. 8. The tube connector as in claim 5 , wherein the male portion comprises a hex portion for engaging a wrench.
