A wing nut includes a body having a sidewall that surrounds a central opening. The central opening is threaded along a threaded portion having a threaded length extending from the back end towards the front end of the body. At least two wings are integrated with the sidewall and extend away from the sidewall in a radial direction relative to the centerline. A rib extend peripherally around the sidewall in a radially outward direction such that a wall thickness of the sidewall increases to a maximum value moving along the centerline away from the rear end, and decreases along the centerline moving towards the front end from the maximum value.

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.

Nut for joining conduits

A swivel joint includes a first pipe section and a second pipe section. The pipe sections may define a flow path via which fluid passes through the swivel joint. One or more surfaces proximate a junction of the first pipe section and the second pipe section may be selectively coated to resist wear from erosion, corrosion, and or abrasion.
