Abstract
A nut for joining conduits includes a body having a generally cylindrical shape and defining a central opening. A plurality of lugs can extend outwardly from an outer surface of the body and provide one or more strike surfaces. The central opening can include a threaded portion proximate a first end of the nut and a tapered portion extending from the threaded portion. The tapered portion defines a frustoconical surface that expands the central opening beyond the threaded portion. The tapered portion may terminate at an undercut or flange proximate the second end of the nut.
Claims20
A nut comprising:
- a body having a generally cylindrical shape extending along an axis from a first end to a second end, the body including a sidewall defining an outer surface of the body and a central opening around the axis, the central opening comprising:
- a first surface extending a first distance from the first end of the body;
- at least one thread formed on the first surface;
- a second surface adjacent the first surface and extending away from the first surface and toward the second end, the second surface being angled relative to the first surface;
- and
- a third surface proximate the second end, the third surface being disposed radially inwardly of the first surface and the second surface;
- and
- a plurality of lugs extending radially outwardly from the outer surface of the body.
A nut comprising:
- a body having a generally cylindrical shape and extending along an axis between a first end and a second end, the body defining a central opening including a threaded surface proximate the first end and a tapered surface extending between the threaded surface and the second end, a first radius at a first axial position of the tapered surface relatively closer to the first end being smaller than a second radius at a second axial position of the tapered surface relatively closer to the second end;
- at least one thread formed on the first surface;
- and
- a plurality of lugs extending radially outwardly from the outer surface of the body.
A nut comprising:
- a body having a generally cylindrical shape along an axis between a first end and a second end, the body defining a central opening including a substantially cylindrical threaded portion proximate the first end, a frustoconical portion extending from the threaded portion toward the second end, and a third substantially cylindrical surface proximate the second end, a radius of the frustoconical portion being relatively smaller proximate the threaded portion and relatively larger away from the threaded portion and the third substantially cylindrical portion having a radius less than a radius of the threaded portion;
- at least one thread formed on the first surface;
- and
- a plurality of lugs extending outwardly from the outer surface of the body.
