A device for a hose fitting having at least one cartridge housing with a first connecting piece or a spray plate with a second connecting piece and a hose, which can be connected at least to the first connecting piece or the second connecting piece, whereby further a clamping sleeve is provided, which clamps an end region of the hose on the outside at least to the first connecting piece or the second connecting piece and with an inward directed collar encompasses a projection of the first connecting piece or of the second connecting piece. A non-metallic, inseparable snap connection is formed with two clamping sleeves toward the cartridge housing and toward the spray plate.

An expander tool (1) includes a tool head (2) which includes expanding means (3) insertable inside the end of the pipe (P), and which includes a plurality of spreading elements (4) that are radially movable in relation to a center longitudinal axis (x) of the tool head (2) between a starting position (I) and an outwardly extended expansion position (II), and that have an outer spreading surface (5) configured to press against an interior surface of the end of the pipe (P). Expander tool (1) includes a piston (6) to spread spreading elements (4) by moving along the axis (x) from a retracted piston position (III) to a fully extended piston position (IV) against interior surfaces of the spreading elements (4), and an actuator (7) for moving piston (6). Outer spreading surfaces (5) include a circumferential groove (8) that leaves an undamaged smooth and intact surface to the inner surface.

A joint is connected to a tube and includes a joint body, nut, and ring. The joint body has a tube coupling part and a main body thread part. The nut has a nut thread part and a constricted diameter part. The ring is arranged in a space radially inward of the nut thread part. The ring abuts an abutted part of the nut. The ring has a Young's modulus greater than the tube. The ring has a curved surface part at least at a radially inward portion of the ring axially on the joint body side, the curved surface part bulging radially inward of the ring and axially toward the joint body side. A maximum thickness of the ring in a radial direction is defined as 2r, an axial length of the curved surface part of the ring is defined as h, and α=h/r being 0.5 to 1.2.

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.

A shield assembly for logging tool sensors includes a single piece cylindrical shield and first and second cylindrical end clamps deployed about opposing axial ends of the cylindrical shield. The cylindrical shield is deployed about a logging sensor disposed on a logging tool collar. At least one of the first and second end clamps includes one or more keys for engaging a corresponding slot in the shield and a corresponding pocket in an outer surface of the tool collar. Engagement of the key with the corresponding slot and the corresponding pocket is operative to prevent relative rotational and relative axial motion between the cylindrical shield, the first and second end clamps, and the tool collar.

An apparatus comprising a sleeve. The sleeve has an outer surface and a flange extending from the outer surface. The flange has a first surface for engaging an edge of first flexible hose and a second surface for engaging a union. The first surface of the flange has a radial length substantially equal to a thickness of the edge of the first flexible hose. The sleeve counteracts a deflection of the first flexible hose and the second flexible hose into a flow path created through the first flexible hose and the second flexible hose when the first flexible hose and the second flexible hose are coupled together using the union, the sleeve, and a pair of fittings.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

A sealed sleeve installed at an insertion coupling portion in a state in which a first pipe and a second pipe are insertion coupled to each other in order to seal couple the first pipe having a first outer diameter and a first inner diameter and the second pipe having a second outer diameter and a second inner diameter larger than the first outer diameter includes: a pillar shaped-main body having a main body central shaft; a through-hole formed using the main body central shaft as a central shaft on the main body and having an inlet as a second pipe side opening in an installation state and an outlet as a first pipe side opening in an installation state, wherein in the through-hole, a pressing portion that applies a sealing pressure to the insertion coupling portion is formed in a portion of an inner wall, and an inner diameter of the pressing portion is smaller than the second outer diameter.

A connecting kit for an irrigation hose includes a hollow male body having, at a relative end, a connector including an end head and a hollow female body, including a second seat for the end head and having a second longitudinal extension greater than a first longitudinal extension of the end head.
