A joint is used to connect two hoses to each other without having to rotate the hoses relative to each other. The joint includes two connectors, an adapter and a ring. Each of the connectors is connected to one of the hoses. The first connector is connected to the adapter while the ring is located between a section of the first connector and a portion of the adapter longitudinally while the ring is allowed to rotate relative to the combination of the first connector with the adapter. The ring is engaged with and disengaged from the second connector by rotating the ring relative to the second connector.

Modular end apparatus, such as modular end fitting apparatus, and methods for flexible hoses, and associated components thereof. In one implementation, a flexible hose apparatus includes a flexible hose and a hose body coupled to the flexible hose, the hose body including a threaded outer surface. The flexible hose apparatus includes a cap including an inner shoulder protruding inwardly relative to a first inner surface of the cap. The flexible hose apparatus also includes a removable end fitting disposed in engagement with the cap. The removable end fitting includes an end body that is monolithic. The end body includes a first end, a second end opposite of the first end, and a first outer shoulder adjacent the first end and disposed between the hose body and the inner shoulder of the cap.

A split coupler, and methods of making and using such a split coupler, whereby the split coupler includes a first semi-cylindrical member, a second semi-cylindrical member, and an interlocking assembly configured to interlock the first and second semi-cylindrical members to form a substantially cylindrical coupler having a coupler inner surface which defines a throughbore. Additionally, the split coupler can include spiral threads coupled to the coupler inner surface. Furthermore, the split coupler can include a flange inwardly extending from the coupler inner surface.

A tubing nut fastener having elements that are partially rotatable with respect to each other. In between the rotatable elements, engagement members (e.g., balls) are captured within interior channels. The partially rotatable elements include permanent markings or other non-removable visual indicators, which varies spatially depending on whether the tubing nut fastener is in a torqued state or an un-torqued state, thereby providing a visual indication of the status of the tubing nut fastener.

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 fluid fitting includes a nut, a sleeve, and a union. The union and the nut may include corresponding stops and corresponding markings. Corresponding stops and corresponding marking may engage with each other when the nut is sufficiently connected with the union. A method of connecting a fitting includes connecting a sleeve of the fitting with a nut of the fitting, connecting the nut with a union, rotating at least one of the nut and the union until a stop of the nut engages a stop of the union, restricting over torque via the stop of the nut and the stop of the union, and verifying a sufficient connection if first markings of the nut align with second markings of the union.

In some implementations, a flowline connector assembly may include a first flowline member having a first cylindrical passageway, and a second flowline member having a second cylindrical passageway. The flowline connector assembly may include a pin, configured to be inserted into the first cylindrical passageway and the second cylindrical passageway, including a stop extending radially outward from an outer surface of the pin, where a first side of the stop is configured to contact a face of the first flowline member when the pin is inserted into the first cylindrical passageway. The flowline connector assembly may include a collar configured for threaded engagement at a first end with an outer surface of the first flowline member, wherein an inner surface of the collar is configured to contact a second side of the stop to connect the first flowline member with the second flowline member.

A tube fitting device for facilitating tube connection position determination includes a fitting body, a pair of fixing nuts, and an O-ring. The fitting body has a cylindrical channel portion into which a first tube and a second tube may be inserted, the cylindrical channel portion comprising an accommodation groove formed therein. Each fixing nut is rotatably coupled to a respective open end of the fitting body and surrounds the first tube and the second tube, respectively. The O-ring is mounted on the accommodation groove and has an inner diameter smaller than that of the cylindrical channel portion such that the inner surface of the O-ring protrudes inside the fitting body to facilitate determining positions of the first tube and the second tube to be inserted into the cylindrical channel of the fitting body.

A riser support assembly includes a riser support pipe comprising a sidewall defining a first end, a second end opposite the first end, and an intermediate portion extending therebetween, the intermediate portion configured to extend through an elevated support structure; and a mount extending from the sidewall, the mount configured to engage a mounting surface of the elevated support structure to support the riser support assembly on the mounting surface.
