4" TTMA Sightglasses and Flanges

The BF4 series of sightglasses and flanges are made to suit 4" TTMA flanges/piping.

Flanges provide the ability to make a removable connection between two points.

Sightglass flanges bolt directly behind an outlet adaptor and provide the ability to view product in piping to ensure if a compartment/tanker has product present or if it has been drained.

Liquip can supply BF4 sightglasses as single units or in "Kits". A Kit is a part that combined two or more parts e.g. a BF4-SG-25Z is a sightglass supplied with a mating 4" TTMA gasket. Please see ordering information tab for further detail.
