An isolation valve unit with a fusion outlet including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port from which the fusion outlet extends. In one embodiment, the thermoplastic end is composed of a PP-RCT material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to couple to a larger polymeric pipe and to control the flow of fluids in a plumbing system via actuation of the ball valve.

A hose joint assembly includes a fitting, a hose receivable onto the fitting, and an adhesive for bonding the hose and the fitting together. For example, the adhesive is a microencapsulated two-part epoxy adhesive that functions as a lubricant when assembling the hose onto the fitting before curing.

A connection for a fluid includes a pipe; a connector in which a fluid is flows, and a housing in which the pipe is at least partially inserted. The pipe and the connector are in fluidic communication. A gasket is arranged in the housing and radially interposed between the pipe and the connector to prevent any leakage of fluid between the pipe and the connector. A closing element in which the pipe is inserted, is mounted both to the pipe (2) and to the connector by two respective welds ensuring fluid tightness.

A pipe adapter includes a first tubular element having a first portion and a second portion axially adjacent the first portion defining a socket. A second tubular element has a first portion and a second portion axially adjacent the first portion, the first portion defining a distal end sized for insertion into the socket and having a radially extending stop. An annular sealing member is located between the first portion of the second tubular element and the second portion of the first tubular element and provides an axial seal therebetween. An annular securing member is rotatably disposed around the first portion of the second tubular element and located within and fixed to the socket. The annular securing member contacts the stop to secure the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and annular securing member.

A pipe adapter includes a first tubular element, a second tubular element, and an annular securing member disposed around and fixed to a second portion of the first tubular element. The annular securing member has a flange portion that contacts and secures the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and the annular securing member. An annular sealing member is located around the first portion of the second tubular element to provide an axial seal along the adapter.

A plastic coolant fitting for a hybrid module includes an upper coolant tube with a first straight section and a rounded section, and a lower coolant tube with a second straight section fixed to the rounded section by spin welding. The rounded section may include a ring-shaped groove and the second straight section may include a ring-shaped protrusion installed in the ring-shaped groove. Prior to spin welding, the ring-shaped groove and the ring-shaped protrusion may include respective complementary trapezoidal cross-sections.

An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.
