A diesel exhaust fluid transfer circuit providing a fluid transfer connector for securely connecting a port fitting of a diesel exhaust fluid device to a diesel exhaust fluid hose. The fluid transfer connector comprises an attachment nut attachable to a port fitting of the diesel exhaust fluid device. The fluid transfer connector further comprises a hose adapter including a fluid conduit and an annular wiper seal coaxially aligned with the fluid conduit. With the attachment nut attached to the port fitting, the fluid conduit is slidable over the port fitting and connectable to the attachment nut, and the annular wiper seal wipes any residue on the port fitting as the fluid conduit is slid over the port fitting.

A transition adapter for a conduit system includes a body having a first end, a second end, and a hollow core. The transition adapter further includes a first threaded portion configured for connection to a conduit fitting or a cord grip fitting, a second threaded portion configured for connection to a conduit body, and a flange surface for receiving a gasket of the conduit fitting or the cord grip fitting.

A kit for connecting to a processing container a device for feeding a liquid or semi-liquid food product, including at least: an internally hollow pipe having a first end and a second end, wherein at least one between the first and the second end includes an enlarged, external terminal portion; a receiving element provided with a hole for receiving at least the enlarged, external terminal portion at one end of the pipe and with an abutment for stopping the end of the pipe inside the hole; a pushing portion for pushing and locking the enlarged, external terminal portion at the end inside the receiving hole in order to allow locking the enlarged, external terminal portion against the abutment.

A first peripheral wall end portion of a conversion adapter is connected to a tubular body across a gasket, and has either an annular protrusion to be pressed into an annular groove on a side surface of the gasket, or an annular groove to allow an annular protrusion projecting from a side surface of the gasket to be pressed thereinto. The first peripheral wall end portion has either an internally threaded portion to allow an externally threaded portion of the tubular body to be screwed thereinto, or an externally threaded portion to allow a nut to be screwed thereonto. The nut also allows an externally threaded portion of the tubular body to be screwed thereinto. A second peripheral wall end portion of the conversion adapter has an externally threaded portion to allow another nut to be screwed thereonto, and then, to allow the sleeve to make contact with the inside.

A pipe joint device includes a nut defining a threaded hole and including an inward flange that defines a through hole and that has a shoulder surface facing the threaded hole, a tube body having inner and outer end portions, and a stopper detachably sleeved on the tube body. The inner end portion extends through the through hole, has an inner end surface and an outer peripheral surface connected to the inner end surface and formed with an external thread. The stopper has opposite first and second abutment surfaces and an inner surface formed with an internal thread threadedly engaging the external thread. The inner end portion further extends through the stopper, such that the second abutment surface faces and abuts against the annular shoulder and the first abutment surface is disposed not farther away from the outer end portion than the inner end surface.

A dielectric union ball valve utilizes a non-conductive separation sleeve to prevent contact between the union and the nut of a dielectric valve assembly. The valve assembly can optionally include an independently operated drain valve port to permit draining of the valve assembly. The use and positioning of a non-conductive separation sleeve mitigates potential galvanic reaction between dissimilar pipes and/or fittings that are connected to the valve assembly.

A hose connecting device has a connector, an inner locking ring, an outer connector and a tubal body. The connector has an insertion section and an engaging section, the engaging section has a size greater than the insertion section, and the engaging section further has a stopping ring at a top end. The inner locking ring is jacketed onto the engaging section of the connector and abutting the stopping ring of the connector. The inner locking ring has an outer threaded section and an abutting portion disposed at a bottom end of the inner locking ring. The outer connector has one of a female connector and a male connector, and a channel, the channel has a positioning step at a middle portion, an inner threaded section disposed below the positioning step of the channel. The tubal body is jacketed onto the insertion section of the connector.

A smart torque system includes a fitting comprising a fitting body defining a fluid flow passage from a first end to a second end, and an electronically readable element that is configured to store information about the fitting including at least a torque requirement of the fitting; an electronic reading device that reads the torque requirement from the electronically readable element; and a torque tool that is programmable by the reading device to set a torque to be applied by the torque tool in accordance with the torque requirement. The electronically readable element may include an RFID or NFC storage device, or a patterned code element, that is read by a complementary reading device. The electronic reading device may be incorporated into the torque tool. In another aspect, a fitting includes a fitting body defining a fluid flow passage from a first end to a second end, and an integrated torque sensor. The integrated torque sensor includes an electronic sensor element; a push pin that is engageable with the electronic sensor element to close a circuit connected to the electronic sensor element; and a biasing element that is configured to actuate the pushpin. When the fitting is torqued in accordance with a torque requirement of the fitting, the biasing element actuates the push pin to engage with the electronic sensor element to close the circuit, and a stored data item within the electronic sensor element changes to indicate the fitting is torqued in accordance with the torque requirement.

A torque limited fitting is provided having a head and a body, which in certain embodiments may be assembled by an operator. The body of the torque limited fitting has a passageway therethrough for receiving and removably holding tubing. The torque limited fitting may be adapted for use with a flat bottom port, such as in an analytical instrument, like liquid chromatography, gas chromatography, ion chromatography, or in in vitro diagnostic systems.
