A swage or coupling tool is provided for use in coupling a fluid line to a compression fitting, a fluid coupler, or the like. The swage tool provides multiple degrees of freedom and/or multiple pivots or pivot joints to facilitate and maintain alignment of the jaws with the compression fitting during use of the swage tool to facilitate properly-aligned assembly of the compression fitting, and to limit bending or kinking of the fluid line when the fitting is being attached. The swage tool includes a pair of movable jaws, which may have stepped or rounded engagement surfaces, which may be forced against corresponding engagement surfaces of the compression fitting to securely assemble the fitting to the fluid line. The shape of the engagement surfaces facilitates properly-aligned assembly of the compression fitting, and limits bending or kinking of the fluid line when the fitting is being attached.

The invention relates to a hose connector system (1) for use in an agricultural spreader machine (15), which system is characterized by rapid and secure assembly, and therefore economical production and high modularity.

An irrigation hose connector and connector component includes a fixing sleeve, limiting sleeve and pipe locking sleeve. The fixing sleeve is arrange outside a water source interface. The limiting sleeve is inserted into the water source interface and the end is integrally arranged with one end of the fixing sleeve. The limiting sleeve is provided with an activity space. The pipe locking sleeve is movablely arranged in the activity space of the limiting sleeve and one end is limited to the outside of the water source interface. A plurality of slottings are provided at intervals on the side wall of one end of the pipe locking sleeve. A locking part is arranged on the inner side wall of the pipe locking sleeve and between the two slottings.

A tubing junction assembly may include a body, and a collar coupled to the body. The body may include a head portion, a base portion, and an intermediate portion. At least a portion of an outer surface of the body at the intermediate portion may define a cross-sectional width that tapers from the head portion to the base portion. The collar may have an inner surface defining a passage. A tubing may be stretched over the outer surface of the body with a proximal end portion of the tubing stretched over at least a portion of the outer surface of the body at the intermediate portion. The inner surface of the collar may be sleeved over a portion of the outer surface of the tubing and coupled to the collar such that the proximal end portion of the tubing is sandwiched and compressed between the body and the collar.

A connecting assembly for operatively and fluidly connecting at least first and second hose segments together. The connecting assembly includes at least one insert portion, and corresponding bulge(s), securing device(s) and fluid passage(s). The securing device is removably mounted onto and displaceable about a portion of a given length span of the insert portion, and configured for operation between a first release mode, where the securing device being is drawn away from the bulge and thus an extremity of the hosing segment is releasable, and a second connecting mode, where the securing device is removably and selectively displaced over an outward overlapping of the extremity of the hosing segment extending over the bulge, so as to securely maintain said extremity of the hosing segment in place, operatively against the bulge and thus, prevent the first extremity of the first hosing segment from being removed from the bulge.

A hose with a metal fitting includes a hose; a metal fitting including a metal-fitting cylindrical portion to which one end portion of the hose is connected; and a sleeve covering the hose and the metal-fitting cylindrical portion. The inside of the hose communicates with the inside of the metal fitting. The hose includes an inner-surface resin layer, a metal-wire reinforced layer, and an outer-surface resin layer which are lined up in order from the inner side of the hose. The inner-surface resin layer is formed of a single layer containing fluororesin. The sleeve includes a first cylindrical portion covering the metal-fitting cylindrical portion; and a second cylindrical portion which directly covers the hose and which is smaller in diameter than the first cylindrical portion. The length of the second cylindrical portion is 8 mm or more. The thickness of the second cylindrical portion is 1 mm or more. The hardness of the second cylindrical portion is measured in compliance with JISK6253 by Durometer Type A and is 70 or more and 95 or less. A material of the sleeve is thermoplastic elastomer or rubber. The material of the sleeve is the same as a material of the outer-surface resin layer.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

Connection for a fluid includes a hose configured for fluid to flow, has an outer layer of polymeric material, an inner layer of polymeric material, and at least one intermediate layer, interposed between the outer and inner layers, made from net, mesh, braid, spiral-wrapped wire, textile fibres, fabric, or non-woven fabric. A connector, in which the fluid is flowable is in fluidic communication with the hose. The hose is mounted around a male portion of the connector. A ring made of polymeric material, is mounted around the hose at the male portion of the connector. When mounted around the hose at the male portion, the ring is deformed and exerts compression on the hose because of such deformation.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

Disclosed are chromatography systems employing a releasable coupling 100 for holding a fluid tubing to a spigot, the coupling comprising: a cylindrical inner component 110 for accepting a fluid tubing 30, said inner component including a resiliently deflectable portion 118 arranged to urge an outer surface of the tubing toward a spigot; and a cylindrical collar 130 having and internal through-aperture 132 for slideably accepting the inner component, the aperture and resilient portion having complementary surface formations which in a first position of the collar mounted to the inner component provide for said resilient deflection in use, and which in a second different position do not cause said deflection, the coupling being characterized in that the collar comprises a collar flange 134 extending outwardly away from the aperture of a size allowing manual manipulation of the collar between the first and second positions. Chromatography systems employing said couplings is disclosed also.
