The present technology generally relates to devices, systems and methods for providing robust sealing between surfaces in a pressurized system, such as a chromatography system. In particular, the devices, systems and methods relate to compliant and resilient parts that can be reused and/or reinstalled while providing a pressure tight sealing surface even within a high pressure environment (e.g., 1000 psi or greater).

A drain-pipe interface device is disclosed. The drain-pipe interface device may include a hollow profile defining a threaded portion located on an outer surface the hollow profile. The threaded portion is configured to engage with an opening associated with a drain-pipe, to couple the drain-pipe interface device with the opening. The drain-pipe interface device may further include a handle provided on the hollow profile. The handle may be used to rotate the drain-pipe interface device couple with the opening.

A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

Example aspects of a tight-seal piping component, a tight-seal piping assembly, and a method for preventing leaking in a piping assembly are disclosed. The tight-seal piping component can comprise a fitting body defining a fitting inner surface, a fitting outer surface opposite the fitting inner surface, a first fitting end, and a second fitting end opposite the first fitting end, the fitting inner surface defining: an interior channel defining a fitting axis; a seal stop surface within the interior channel; and internal threading between first fitting end and the seal stop surface, the internal threading defining straight threading extending in a direction about perpendicular to the fitting axis; and a seal received within interior channel and abutting seal stop surface.

A modular connector system is designed and configured for setting various building material members in place prior to construction of a wall. The modular connector system includes a base plate, a vertical riser member, at least one horizontal arm, and a connection member for each of the at least one horizontal arms. The base plate is configured to support the modular connector system. The vertical riser member is affixed to the base plate in a vertical orientation. Each of the at least one horizontal arm is configured to be adjustably positioned along the vertical riser member. The connection member on each of the horizontal arms is configured to attach to one of the building material members. Wherein, the disclosed modular connector system is designed and configured for setting the building material members in place prior to construction of the wall.

A connecting apparatus for creating a connection to a measuring instrument or to a valve block/valve with a measuring instrument, and a connection to a pipeline or to a metering orifice device installed in a pipeline comprises: a first connecting device that provides a sealing connection to the pipeline or to the metering orifice device with a first recess extending through in the longitudinal direction, and a second connecting device that provides a sealing connection to the measuring instrument or to the valve block/valve with a second recess extending through in the longitudinal direction. The first and second connecting devices are interconnected with sealing effect. The connecting unit is designed so that the sealing connection can be created solely by rotation of the connecting unit without rotating the first and second connecting devices.

A tube adapter for a pipeline for conveying a medium includes a pipeline section having a tubular, first channel for inserting the pipeline section into the pipeline, and a tubular, second channel, which is arranged at a first predeterminable angle to the first channel and connected with the first channel. In a transition region between a wall of the first and a wall of the second channel, at least one hollow is present in a wall of the first and/or second channel. The present disclosure further includes an arrangement having a measuring device and a tube adapter according to the present disclosure as well as to a method for producing a tube adapter according to the present disclosure.
