A fuel fitting assembly includes a monolithic fuel fitting formed by additive manufacturing. The fitting includes a first end, a second end, a conduit extending axially through the fitting from the first end to the second end, and a first sealing element. The first end is to be connected to a fuel line. The second end is to be connected to a device requiring or providing fuel. The first sealing element includes a sealing seat circumferentially surrounding the conduit at the second end of the fitting. The fuel fitting is integrally formed as a stack of layers of material.

A shower head adapter includes a body part, which has one side connected to the inner circumferential surface of the inlet side of a main shower head body and the other side connected to a hose. The shower head adapter also includes a first circular groove formed along the outer circumferential surface thereof and a main body connecting part, which has an end on the other side protruding inwards from the inner circumferential surface thereof. A part of the inner circumferential surface is coupled to the outer circumferential surface of the inlet side of the main shower head body. A snap ring is inserted in the first circular groove. The diameter of the outer circumferential surface of the snap ring is larger than the diameter of the protruding inner circumferential surface of the main body connecting part.

A connector assembly for an adhesive dispenser is provided and includes a drum fixture seated into a drum containing an adhesive material. The drum fixture is configured for fluid communication with the drum. A hose fixture is connected to the drum fixture and configured for fluid communication with the drum fixture. The hose fixture is configured for insertion and rotation to form the connection with the drum fixture. The hose fixture includes a latch assembly configured to prevent rotation of the hose fixture. A seal member is disposed between the drum fixture and the hose fixture. The seal member is configured to facilitate fluid communication between the drum fixture and the hose fixture. The seal member is configured to prevent leakage of fluid materials between the hose fixture and the drum fixture. The latch assembly requires manual intervention to remove the hose fixture from the drum fixture.

A fitting nut made of a resin material includes: a hollow, large-diameter tube portion having a female thread formed on its inner peripheral wall; and a small-diameter tube portion that is continuous to the large-diameter tube portion and having a hollow cylindrical shape with a smaller diameter than the large-diameter tube portion. The small-diameter tube portion includes, in the outer peripheral wall thereof, a plurality of engagement grooves that are depressed inwardly in the diameter direction of the small-diameter tube portion and extend along the longitudinal direction that is orthogonal to the diameter direction.

An arrangement is disclosed having a clamp body configured in a cylindrical shape and having four penetrations that each have a bolt hole penetration with a first side penetration and a second side penetration and at least four jaws, each of the at least four jaws configured to be inserted into one of the at least four penetrations, each jaw having a first side and a second side.

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.
