Product overview
Union-Nut Tank Port and Bracket-Mounted Cylindrical Tube Lamp
This union-type tank sight glass welds onto a vessel nozzle or head and retains its circular viewing glass with a slotted sanitary union nut. Unlike the hinged-lamp variant, it mounts a vertical cylindrical stainless steel tube lamp with a cable gland atop a dual-leg support bracket fastened to the union ring.
Material Grades and Seal Options
Manufactured from 304 (1.4301) or 316L (1.4404) stainless steel (with SS304, SS304L, SS316, and SS316L listed in the table), the assembly uses silicone, EPDM, Viton, or NBR seals.
Nominal Size and Series schedule Scope Note
The specification table lists Specification: DN150 across SMS, DIN, 3A, IDF, RJT, BS, and ISO standards. Several rows in the series specification and body text (such as 360-degree inline flow viewing, 3/4"–6" sizes, and polycarbonate/acrylic tubing covers) are generic inline tubular sight-glass text carried over in the series documentation.
Pre-Weld Disassembly and Ordering Notes
Unscrew the union nut and remove the tube lamp, glass disc, and gasket prior to welding the base neck onto the vessel. Confirm nominal port size and lamp electrical specifications when ordering.
