Abstract: A plunger lift lubricator having an internal bypass configuration which enables a plunger to be reliably captured and while still allowing the flow of fluid up through the lubricator before the fluid is directed radially outward and down the internal bypass passageways. The lubricator can comprise both an upper flow path and a lower flow path and can be configured such that a plunger can travel all the way up to shift a valve in the plunger if needed.

Abstract: A strong connection that ensures alignment between components and which is capable of being used for high-pressure applications. The connection is held together with one or more pins that are positioned tangentially along the interfacing plane of the components and which pins are positioned such that they are placed in sheer along a significant portion of their length instead of merely across their diameter. The pins can be held in place with one or more structures, which can include threaded fasteners, to prevent the pins from being inadvertently removed.
