Mechanical branch outlet

1. A mechanical branch outlet comprising:

a housing having an outer surface and an inner surface and defining an outlet bore extending between the outer surface and the inner surface; and

an insert having a first end and a second end, the insert defining an axis aligned with the outlet bore of the housing, the outlet bore of the housing sized to receive the second end of the insert and retain the first end of the insert, the insert comprising a rim positioned between the first end and the second end of the insert, a surface of the rim angled with respect to the axis of the insert, an outer diameter of the rim greater than each of the outlet bore of the housing and an outer diameter of the first end of the insert; and

a gasket defining an inner diameter, the inner diameter sized to receive the first end of the insert, the gasket of the mechanical branch outlet comprising a first sealing leg and a second sealing leg, the first sealing leg positioned to contact a pipe when the housing is installed on the pipe, the second sealing leg and a bore of the gasket defined thereby contacting the insert, the gasket further defining a recess in the bore, the bore sized to receive the rim, the rim positioned between and in contact with each of the second sealing leg of the gasket and an inner surface of the housing.

2. The mechanical branch outlet of claim 1 , wherein the gasket defines a lower surface, the lower surface having a cylindrical contour.

3. The mechanical branch outlet of claim 2 , wherein the cylindrical contour of the lower surface of the gasket is substantially coaxial with a longitudinal axis of the mechanical branch outlet.

4. The mechanical branch outlet of claim 3 , wherein the rim of the insert also has a cylindrical contour.

5. The mechanical branch outlet of claim 4 , wherein the cylindrical contour of the rim is substantially coaxial with the longitudinal axis of the mechanical branch outlet.

6. The mechanical branch outlet of claim 1 , wherein the housing is an upper housing and includes ductile iron.

7. The mechanical branch outlet of claim 1 , wherein the rim is sized to retain a first end of the insert inside the housing, the rim being integral with the material of the insert.

8. The mechanical branch outlet of claim 7 , wherein:

the recess is defined between the second sealing leg and an upper surface of the gasket, the upper surface of the gasket in contact with the housing.

9. The mechanical branch outlet of claim 1 , wherein the gasket defines a pocket between the first sealing leg and the second sealing leg, the pocket facing radially inward and angularly away from the housing and configured to strengthen the seal formed by the first sealing leg against the pipe.

10. A pipe system comprising the mechanical branch outlet of claim 1 , the pipe system further comprising

a pipe, the pipe defining a transverse bore in an outer wall of the pipe sized to receive the first end of the insert, the mechanical branch outlet being assembled to the pipe.

11. The pipe system of claim 10 , wherein the insert extends from the pipe at an angle to a longitudinal axis of the pipe that is substantially equal to 90 degrees.

12. The pipe system of claim 10 , wherein a curvature of the gasket and a curvature of an outer diameter of the pipe share a common axis when the gasket is in a non-assembled state.

13. The pipe system of claim 10 , wherein the housing is isolated from a fluid path defined through the pipe and through the insert when the pipe system is in an assembled state.

14. The pipe system of claim 10 , wherein the gasket defines a recess between the second sealing leg and an upper surface of the gasket, the upper surface of the gasket in contact with the housing.

15. The pipe system of claim 10 , wherein the first end of the insert extends through the transverse bore defined in the outer wall of the pipe.

16. The pipe system of claim 10 , wherein the insert extends through the outlet bore of the housing, the pipe system further comprising a piping system element having a crimped joint crimped to an exposed portion of the insert.

17. A method for assembling the mechanical branch outlet of claim 1 to a pipe, the method comprising:

positioning the first end of the insert of the mechanical branch outlet into a transverse bore defined in an outer wall of the pipe; and

assembling the housing of the mechanical branch outlet to the pipe, the housing being isolated from a fluid path defined through the pipe and through the insert when the pipe system is in an assembled state.

18. The method of claim 17 , wherein the pipe is a first pipe, the method further comprising connecting a piping system element to the insert, the piping system element being a crimp fitting.

19. The method of claim 17 , further comprising:

assembling the gasket to the pipe between the housing and the pipe by contacting the first sealing leg of the gasket with an outer surface of the pipe;

contacting the second sealing leg of the gasket with an outer surface of the insert of the mechanical branch outlet; and

inserting the rim of the insert into the recess of the gasket, the recess defined between the second sealing leg and an upper surface of the gasket, an outer diameter of the rim being greater than an outer diameter of a second end of the insert, the second end of the insert distal from the first end of the insert; and

contacting the housing with each of the upper surface of the gasket and the rim of the insert.
