Abstract
A sub-sea coupling comprises a female coupler which accommodates a conical metal seal and an adjacent striker constituted by a sliding ring. The female coupler also includes a U-section seal outwardly of the striker. A male coupler has a forward probe with an intermediate part of slightly greater diameter than the extreme forward part. A shoulder between the intermediate and extreme parts of the probe engages the striker to cause the conical seal to flatten and thereby to provide a metal-to-metal radial seal between the female coupler and the male coupler. The U-section seal provides a seal against the intermediate part of the probe before the striker is engaged and is also configured to provide no significant resistance to the ingress of seawater when the couplers are disengaged.
