Abstract

A tubular connector includes a first tubular member that includes a female end; a second tubular member including a male end insertable into the female end, each of the first and second tubular members including a bore that extends there through; a clamp positionable about the first and second tubular members to urge the male and female ends into sealing engagement; a housing that at least partially encloses the clamp such that a chamber is defined between the clamp and the housing; and a plate positionable between an axial end of the clamp and the housing.

First claim

What is claimed is:

1. A tubular connector, comprising:
a first tubular member comprising a female end;
a second tubular member comprising a male end insertable into the female end, each of the first and second tubular members comprising a bore that extends therethrough;
a clamp positionable about the first and second tubular members to urge the male and female ends into sealing engagement, wherein each of the first and second tubular members comprises an expanded diameter shoulder portion, and flanged ends of the clamp abut the expanded diameter shoulder portions;
a housing that at least partially encloses the clamp such that a chamber is defined between the clamp and the housing; and
a fastener engageable with the clamp through the housing.

2. The tubular connector of claim 1 , wherein the clamp comprises a first portion and a second portion, the first and second portions urgeable together by the fastener.

3. The tubular connector of claim 1 , further comprising a lock-out assembly positioned on the housing to at least partially cover the fastener.

4. The tubular connector of claim 1 , wherein the fastener comprises a manually-rotatable cap coupled to a threaded rod.

5. The tubular connector of claim 1 , wherein the housing comprises an oblong cross-section.

6. The tubular connector of claim 1 , further including a plate positionable between an axial end of the clamp and the housing.

7. The tubular connector of claim 6 , wherein the plate comprises a first plate, the connector further comprising a second plate positionable between another axial end of the clamp and the housing opposite the first plate.

8. The tubular connector of claim 7 , wherein the housing comprises a respective slot to receive each of the first and second plates therethrough, each respective slot positioned near a respective axial end of the housing.

9. A tubular connector, comprising:
a first tubular member comprising a female end;
a second tubular member comprising a male end insertable into the female end, each of the first and second tubular members comprising a bore that extends therethrough;
a clamp positionable about the first and second tubular members to urge the male and female ends into sealing engagement;
a housing that at least partially encloses the clamp such that a chamber is defined between the clamp and the housing; and
a fastener engageable with the clamp through the housing, wherein the fastener comprises a manually-rotatable cap coupled to a threaded rod.

10. The tubular connector of claim 9 , wherein the clamp comprises a first portion and a second portion, the first and second portions urgeable together by the fastener.

11. The tubular connector of claim 9 , further comprising a lock-out assembly positioned on the housing to at least partially cover the fastener.

12. The tubular connector of claim 9 , further including a plate positionable between an axial end of the clamp and the housing.

13. The tubular connector of claim 12 , wherein the plate comprises a first plate, the connector further comprising a second plate positionable between another axial end of the clamp and the housing opposite the first plate.

14. The tubular connector of claim 13 , wherein the housing comprises a respective slot to receive each of the first and second plates therethrough, each respective slot positioned near a respective axial end of the housing.

15. The tubular connector of claim 9 , wherein the housing comprises an oblong cross-section.

16. The tubular connector of claim 9 , wherein each of the first and second tubular members comprises an expanded diameter shoulder portion, and flanged ends of the clamp abut the expanded diameter shoulder portions.

17. A tubular connector, comprising:
a first tubular member comprising a female end;
a second tubular member comprising a male end insertable into the female end, each of the first and second tubular members comprising a bore that extends therethrough;
a clamp positionable about the first and second tubular members to urge the male and female ends into sealing engagement;
a housing that at least partially encloses the clamp such that a chamber is defined between the clamp and the housing; and
a fastener engageable with the clamp through the housing, further including a plate positionable between an axial end of the clamp and the housing.

18. The tubular connector of claim 17 , wherein the clamp comprises a first portion and a second portion, the first and second portions urgeable together by the fastener.

19. The tubular connector of claim 17 , further comprising a lock-out assembly positioned on the housing to at least partially cover the fastener.

20. The tubular connector of claim 19 , wherein the plate comprises a first plate, the connector further comprising a second plate positionable between another axial end of the clamp and the housing opposite the first plate.
