Abstract: A load limited connector that is calibrated to fail at a predetermined approximate tensile load. The connector includes a main body, within which a pin chamber is received, and a secondary body having a shaft that is releasably secured within the pin chamber. At least one breakaway pin, positioned in a pin passageway passing through the pin chamber and into the main body, secures the pin chamber within the main body. When the connector is subjected to tensile loading that exceeds the yielding point of the breakaway pin, failure of the pin occurs resulting in separation of the main body from the secondary body. A pair of torsion pins extend through the pin chamber into the main body to prevent rotation of the pin chamber relative to the main body.

Abstract: A harsh environment swivel is disclosed. The swivel is of the type having first and second swivel heads located at opposite ends of a generally hollow swivel body. A swivel shaft is attached to the first swivel head and secured within the hollow body by a locking nut. The swivel shaft rotates about tapered roller bearings which transmit tensile loading from the swivel shaft to the hollow body. A plurality of progressively more restrictive seals restrict the passage of debris into the interior of the hollow body. A method of flushing debris from the interior of such a swivel is also disclosed.

The swivel shaft rotates about tapered roller bearings which transmit tensile loading from the swivel shaft to the hollow body. A plurality of progressively more restrictive seals restrict the passage of debris into the interior of the hollow body. In a further embodiment, a swivel having independently rotating swivel heads at either end is disclosed. A method of flushing debris from the interior of a swivel is also disclosed.
