Connector with integral seal

1. A connector comprising:

a tubular connector body with a mating end, an end face at said mating end, an outer diameter, and a center axis, said end face being generally perpendicular to said center axis;

a circular groove within said end face defining a ring with a sealing surface, said ring located radially outward from said circular groove; and

a coupling member mating with said sealing surface, said coupling member having a threaded section configured to connect with a separate device.

2. The connector of claim 1 , further comprising a void in said tubular connector body at an intersection of said outer diameter and said end face.

3. The connector of claim 1 , wherein said ring extends outward from said center axis to help establish a proper sealing contact.

4. The connector of claim 1 , wherein said ring further comprises a compressed state and an uncompressed state, and at least one bend toward said center axis in said uncompressed state.

5. The connector of claim 1 , wherein said ring is elastically deformable such that compressive force can be applied to said seal while connecting said coupling member to said separate device and disconnecting said coupling member from said separate device without permanently deforming the shape of said seal.

6. A connector comprising:

a tubular connector body with a mating end, an end face at said mating end, an outer diameter, and a center axis, said end face being generally perpendicular to said center axis;

a circular groove within said end face defining a ring with a sealing surface, said ring located radially outward from said circular groove, said sealing surface defining an annular outer wall of the ring; and

a coupling member having an annular inner wall mating with said sealing surface, the sealing surface having a diameter larger than a diameter of the annular inner wall, the ring compressing such that the sealing surface flexes into the circular groove to allow a compression fit within the annular inner wall of the coupling member, said coupling member having a mating end configured to connect with a separate device.

7. The connector of claim 6 , further comprising a void in said tubular connector body at an intersection of said outer diameter and said end face.

8. The connector of claim 6 , wherein said ring extends outward from said center axis to help establish a proper sealing contact.

9. The connector of claim 6 , wherein said ring further comprises a compressed state and an uncompressed state, and at least one bend toward said center axis in said uncompressed state.

10. The connector of claim 6 , wherein said ring is elastically deformable such that compressive force can be applied to said seal while connecting said coupling member to said separate device and disconnecting said coupling member from said separate device without permanently deforming the shape of said seal.

11. A connector comprising:

a tubular connector body with a mating end, an end face at said mating end, an outer diameter, and a center axis, said end face being generally perpendicular to said center axis;

a circular groove within said end face defining a ring with a sealing surface, said ring located radially outward from said circular groove; and

a coupling member mating with said sealing surface such that no portion of the coupling member is located within the circular groove, said coupling member having a mating end configured to connect with a separate device.

12. The connector of claim 11 , further comprising a void in said tubular connector body at an intersection of said outer diameter and said end face.

13. The connector of claim 11 , wherein said ring extends outward from said center axis to help establish a proper sealing contact.

14. The connector of claim 11 , wherein said ring further comprises a compressed state and an uncompressed state, and at least one bend toward said center axis in said uncompressed state.

15. The connector of claim 11 , wherein said ring is elastically deformable such that compressive force can be applied to said seal while connecting said coupling member to said separate device and disconnecting said coupling member from said separate device without permanently deforming the shape of said seal.
