A tubular connector, such as used with a liquid sight monitor, having a plurality of internal deformable ridges for bearing against the external surface of the tube of the monitor. Hence, it accommodates to a range of sizes and irregular tube shapes. The connector is made of a material that in a thick dimension is not deformable, but in a small dimension is deformable, such is Teflon FEP. The body is thick enough to be rigid, whereas the ridges are complaint, more so in a direction toward the mounting end of the connector or end of the tube. Pressure leakage form the liquid system to which the sight monitor is attached increases the pressure seal of the ridges with respect to the surface of the tube. Concentric tube sight monitors are connected to their systems using a connector having, in addition to the set of ridges for accommodating to the internal tube in the manner just described, a second set of ridges for conforming to an external tube. This second set of ridges can be either outwardly directed or inwardly directed from a concentric slot in the connector and into which the end of the concentric tube is inserted. Other embodiments are also described.
