A tubing coupler. The coupler includes a tubular body and a a stock body portion that is grooveless. The tubing coupler also includes a first engagement end with a first set of grooves disposed thereon to engage with an inside portion of a first piece of tubing. A method of making a customized part with the tubing coupler. The method includes securing at least a portion of the tubing coupler inside a first piece of carbon fiber tubing.

A device for axially connecting two pipe elements, including a coupling means with a first coupling means part assignable to a first pipe element, a second coupling means part and an intermediate connecting part arrangeable between the two coupling means parts, wherein a first articulation element formed on the first or second coupling means part is configured to cooperate with a second articulation element formed on the intermediate connecting part, in particular in a positive manner, forming an articulated connection between the first or second coupling means part and the intermediate connecting part, or a second articulation element formed on the first or second coupling means part is configured to cooperate with a first articulation element formed on the intermediate connecting part, forming an articulated connection between the first or second coupling means part and the intermediate connecting part.

A seal assembly includes a connector body having an open end configured for receiving a free end of a pipe and an adaptor for securing at the free end of the pipe. The adaptor has a first ring, configured to be mounted around the circumference of the free end of a pipe, and a second ring configured to cooperate with the first ring in order to drive the first ring into engagement with an outer surface of the pipe. A mechanical interlock arrangement is configured for driving the adaptor in the direction of the connector body, when the adaptor is secured at the free end of the pipe. The mechanical interlock arrangement is further configured for preventing or limiting axial movement of the pipe relative to the connector body, when the adaptor is secured to the outer surface of the pipe and when the free end of the pipe is in sealing contact with a metal seal surface of the connector body.

Example embodiments of the present disclosure relate to an assembly for sealing a rigid pipe, a furnace, and a gasket for use in an HVAC fluid conduit. Some embodiments include a furnace with an inducer blower drawing combustion air through the furnace, and the assembly is used to connect one or more flue conduit(s) and an exhaust pipe. In one embodiment, the gasket used in the assembly includes a tubular body, at least a portion of which is engaged along an inner surface of the fluid conduit, a rim extending outwardly from a tubular body end, and two or more ears extending from the rim, wherein the ears are spaced apart from the tubular body and extend in substantially the same direction as the tubular body. The ears further include a first rib located proximate a distal end of the ear.

A fluidic connector to connect two ducts of a system such as an air conditioning system. The connector includes at least one elastic material, and includes a duct surrounded by an adjustable clamping collar which, when tightened, serves to deform it to reduce the internal space of the duct. The clamping of the collar makes it possible to easily and quickly regulate the rate of flow in the ducts.

A medium connector including a passage configured to allow for the flow of medium, and a multi-portion engagement surface positioned about the passage. The multi-portion engagement surface includes a first surface portion, and a second surface portion. The first surface portion is configured to provide an interference fit with a corresponding sealing surface of a mating connector. The second surface portion is configured to provide a clearance fit with the corresponding sealing surface of the mating connector. The ratio of the first surface portion and the second surface portion is selected to regulate an engagement force between the medium connector and the mating connector.

Methods, devices, and systems for a universal pipe sleeve junction for an aspirated smoke detection system are described herein. In some examples, one or more embodiments include a sleeve body having an outer surface and an inner surface, the inner surface defining an opening through the sleeve body, wherein the sleeve body further includes a first end surface and a second end surface opposite the first end surface, and a nozzle having an outer surface and an inner surface, the inner surface of the nozzle defining an opening through the nozzle and extending through to the inner surface of the sleeve body, where the nozzle opening is configured to couple with a pipe sleeve attachment mechanism.

An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.
