3" TTMA sightglasses and Flanges

The BF3 series of sightglasses and flanges are made to suit 3" TTMA flanges/piping. 

Flanges provide the ability to make a removable connection between two points.They have a chamfered bore to clear the disc, fitted beside a butterfly valve.

Sightlgasses offer 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 BF3 sightglasses as single units or in "Kits". A Kit is a part that combined two or more parts e.g. a BF3-SGZ is a  sightglass supplied with a mating 3" TTMA gasket. Please see ordering information tab for further detail.
