The core of the mini sight glass is the 5/16 in. bore glass tube that fits into the cage. This is the replacement for the glass only and does not include any gaskets, ends, or the cage body.

The Female NPT 1/4 inch end is one of several adapters available with our mini inline sight glass. The 3/4 inch MNPT connection threads into the cage body sealing the gasket against the glass core. Each sight glass will support two same or different ends.

The Male JIC 1/4 inch end is one of several adapters available with our mini inline sight glass. The 3/4 inch MNPT connection threads into the cage body sealing the gasket against the glass core. Each sight glass will support two same or different ends.

Mini Sight Glass

The long awaited customizable mini sight glass is finally here. The ideal solution for inline reading of fluid flow, color, or opacity; using NPT or JIC fittings. Or, if reading a Tri-Clamp port coming off of a tank or pressure vessel, then transitioning to a JIC or NPT hose. We offer 8 connection options to fit your needs. We also use standard 3/8" Tri-Clamp Gaskets to seal the glass inline, so if your process needs more chemical resistance, changing from a Silicone to an FKM gasket is a simple switch. The high quality borosilicate gauge glass has a through bore of 5/16", maximizing the connection options and visibility, while being short enough to not drastically affect fluid flow from its bore size.
