A method for manufacturing a resin pipe joint with a joint body includes the following steps. Preparing a mold and a supply device configured to supply molten resin. The mold includes a first mold for an outer shape of the joint body and a second mold for an inner shape of the joint body. Combining the second mold with the first mold to form a cavity, into which the molten resin is injectable, inside the mold. Supplying the molten resin to the cavity in the mold. Solidifying the molten resin in the cavity after stop of the supply of the molten resin from the supply device. The second mold has a gap that connects the cavity to a discharge space outside the cavity and allows gas to flow.

Provided is a connection structure of a metal corrugated pipe, including: a first connection member including a first connection member inner guide straight pipe and a first connection member inner inclined pipe; the metal corrugated pipe inserted into the first connection member inner guide straight pipe and the first connection member inner inclined pipe of the first connection member; a second connection member fitted on an outer side of the metal corrugated pipe, and screw-coupled to the first connection member; a metal packing fitted on the outer side of the metal corrugated pipe, and inserted into the first connection member inner guide straight pipe and the first connection member inner inclined pipe so as to be pipe-reduced to form a curved surface; and a separation prevention ring configured to fix the metal packing to prevent the metal packing from being separated.

A fluid-tight hose connection for a surgical instrument including: a hose having an inner hose and an outer protective hose surrounding the inner hose, wherein the inner hose has a coiled hose portion at an end portion of the hose; and a sleeve having a wedge-shape in a longitudinal section, the sleeve being arranged between the coiled hose portion of the inner hose and the outer protective hose.

A fluid fitting includes a nut, a sleeve, and a union. The union and the nut may include corresponding stops. Corresponding stops may engage with each other when the nut is sufficiently connected with the union. A method of designing a fluid fitting including a union may include determining a gauge diameter of the union, determining a plane perpendicular to an axis of rotation of the union that includes a center point of the gauge diameter, determining a point of intersection of threads of the union with the perpendicular plane, and/or determining a position of a stop according to an angle from the point of intersection.

A detachable faucet connector can be used with a faucet to allow easy connection of hoses to the faucet. The detachable faucet connector can include an aerator, a funnel, and a hose adapter. The aerator can connect to a faucet to replace the faucet's existing aerator. The funnel can be inserted in to the aerator prior to the installation of the aerator in the faucet. The hose adapter can be connected to the funnel. The hose adapter can be attached to a hose.

A system for a self-recoiling hose provides an expandible-length hose that automatically condenses to a smaller size upon completion of usage. The sheath includes a set of elastic fibers that is interwoven with a set of rigid fibers, thus allowing the expandable hose to elongate to a maximum length that is within a reasonable predetermined length range. This prevents the inner tube from expanding beyond its intended length. The apparatus further provides a connection mechanism for expandable hoses. The apparatus is designed to prevent any possible leakage between one or more expandable hoses and the apparatus. A threaded connector enables chain attachment of the expandable hose to other hoses. Another unit fits inside the inner channel of an expandable hose, while a third part surrounds the inner channel of the expandable hose. An annular fastener secures the outer channel of the expandable hose to the inner channel.

A convertible hose connector assembly includes a clamping nut, a crimp sleeve, a hose insert, and a replacement pipe. The crimp sleeve is coupled to the hose insert and the hose insert is coupled to the replacement pipe. The replacement pipe replaces a coupler coupled to a convertible top hydraulic cylinder prior to being remanufactured to produce a remanufactured convertible top hydraulic cylinder. The remanufactured convertible top hydraulic cylinder including at least one of the hose connector assembly.

A magnetic duct access door provides for frequent access to a variety of different kinds of duct. The access door allows for an efficient magnetic attraction to a metallic duct and easy manual removal of the access door by tilting the access door via handles on its front surface. The access door includes: an access door base; a plurality of magnets arranged around the periphery of the back surface of the access door base; a compressible sealing member located between the magnetic attachment pads on the back surface of the access door base; at least one handle portion extending from the front surface of the access door base.

A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.

An apparatus comprising a sleeve that comprises a tubular portion, a receiving portion, and a coupling portion. The tubular portion has an outer diameter that is substantially equal to an inner diameter of a flexible hose such that the tubular portion is capable of being inserted within the flexible hose. The receiving portion extends outward from the tubular portion to thereby define a channel between the receiving portion and the tubular portion for receiving an end portion of a flexible hose. The coupling portion is for coupling the sleeve, and thereby, the flexible hose, to a component.
