    Abstract: A fitting assembly is provided with a first fitting component having a stepped wall surface; and a second fitting component radially spaced from the first fitting component when the fitting assembly is in a finger tight condition prior to pull-up. When the second fitting component is displaced into contact with the stepped wall surface during fitting pull-up, the stepped wall surface assists in separating the first fitting component from the second fitting component upon fitting disassembly.

    Abstract: The disclosure presents exemplary embodiments of a cartridge nut concept for conduit fittings. The cartridge nut concept may include the feature of loosely retaining one or more conduit gripping devices with a fitting component such as a male or female threaded nut. The cartridge nut concept may be realized using one or more geometry or shape features or characteristics of one or more conduit gripping devices. Still further, the cartridge nut concept may be realized in combination with a ferrule cartridge concept.

    Abstract: A gas flow valve having an internal valve chamber with an inlet and outlet passage, and a movable metallic diaphragm in the chamber, the diaphragm bonded to a valve stem projecting outside of the chamber. The diaphragm has a Teflon film coating which is engageable against at least one of the inlet and outlet passages in sealing relationship, and the valve stem has a spring-biasing member outside the chamber for urging the diaphragm away from sealing engagement with the inlet and outlet passages. A peripheral rib is formed in a chamber wall and the diaphragm is held in fixed relationship against the peripheral rib.

    Abstract: A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar. Alternatively, the fitting may also be pulled up by turns or may have an integral torque collar. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. In other embodiments, the non-integral torque collar may be installed onto one of the fitting components, and then deformed so as to prevent or make it more difficult to remove the torque collar after installation onto the fitting component.

    Abstract: A drive nut for a fitting includes an interior socket centered on a central axis and configured to receive at least a rearward portion of a conduit gripping member. The socket is defined by a radial drive surface positioned to engage the conduit gripping member during pull-up, a first longitudinal surface radially outward of said drive surface and a tapered second longitudinal surface between the drive surface and the first longitudinal surface, wherein a conduit gripping device contacts the second longitudinal surface upon an initial pull-up and each remake. This geometry facilitates a greater number of available remakes by reducing lost stroke, and can provide less stroke loss for fittings pulled up by torque.
