Abstract
A connector for a fluid conduit is provided herein. The connector includes a conduit structure and an annular seal member. The conduit structure has a frustro-conical surface and a seal groove. The frustro-conical surface may be an external surface or an internal surface, depending upon the desired configuration of the connector. The seal groove is formed into the frustro-conical surface along an axis perpendicular to the frustro-conical surface. The seal groove is preferably defined by a constant radius. The annular seal member is coupled to the conduit structure and disposed at least partially in the seal groove.

A connector for a fluid conduit, the connector comprising:
- a conduit structure having a body portion, a threaded portion, a frustro-conical surface and a seal groove, the sale groove disposed between the threaded portion and the body portion, the seal groove formed into the frustro-conical surface [and] along a place that is perpendicular [thereto] to the surface, the seal groove being defined by a constant radius;
- and
- a compressible annular seal member coupled to the conduit structure and disposed at least partially in the seal groove.
A connector for a fluid conduit, the connector comprising:
- a conduit structure having an externally threaded portion, a seal portion and a body portion, the seal portion disposed between the externally threaded portion and the body portion, the seal portion including a frustro-conical exterior surface and a seal groove, the seal groove formed into the frustro-conical exterior surface at approximately 90 degrees to [the] a plane extending along the exterior surface, and seal groove being defined by a constant radius;
- and
- a resilient seal member coupled to the conduit structure and disposed at least partially in the seal groove.
A hydraulic fitting for a fluid conduit, the fitting comprising:
- a nut having a seal portion, a body portion, and an internal bore, the seal portion including a frustro-conical exterior surface and a seal groove, the seal groove formed into the frustro-conical exterior surface and perpendicular thereto, the seal groove being defined by a constant radius;
- an annular seal member coupled to the nut and disposed at least partially in the seal groove;
- a threaded member extending through the internal bore;
- and
- a female connector engageable with the nut and having a frustro-conical surface.
A fitting for a fluid conduit, the fitting comprising:
- a fitting member having a cap, a threaded portion and a seal portion, the seal portion including a frustro-conical surface and a seal groove, the seal groove formed into the frustro-conical surface and perpendicular thereto, the seal groove being defined by a constant radius;
- an annular seal member disposed at least partially in the seal groove;
- and
- a port for receiving the fitting member.
A connector for a fluid conduit, the connector comprising:
- a body portion;
- a first conduit structure connected to a first end of the body portion, the first conduit structure having a first externally threaded portion and a first seal portion, the seal portion disposed between the first externally threaded portion and the body portion, the first seal portion including a first frustro-conical exterior surface and a first seal groove, the first seal groove formed into the first frustro-conical exterior surface at approximately a right angle thereto, the first seal groove being defined by a constant radius;
- a second conduit structure connected to a second end of the body portion, the second conduit structure having a second seal portion and a second externally threaded portion, the second externally threaded portion disposed between the second seal portion and the body portion, the second seal portion including a second frustro-conical exterior surface and a second seal groove, the second seal groove formed into the second frustro-conical exterior surface and perpendicular thereto, the second seal groove being defined by a constant radius;
- a first annular seal member coupled to the first conduit structure and disposed at least partially in the first seal groove;
- and
- a second annular seal member coupled to the second conduit structure and disposed at least partially in the second seal groove.
