DESCRIPTION
A 12 inch full face gasket in 1/8 in. red rubber, cut to ASME B16.21 for 150 lb flanges. Pipe size is a name, not a measurement — 12 in. pipe is 12-3/4 in. across the outside, which is why the bore reads 12-3/4 in. and the outer edge 19 in.
Measure across your flange face — if it reads 19 in., this is your gasket.
- Fits pipe size — 12 in. nominal
- Outside diameter — 19 in. (matches the flange face)
- Bolt holes — 12, at 1 in.
- Bolt circle — 17 in.
- Bore — 12-3/4 in.
- Thickness — 1/8 in.
- Material — red rubber (SBR), 70 Shore A, -20°F to 180°F
- Flange class — 150 lb steel or 125 lb cast iron
Fits 150 lb steel and 125 lb cast iron flanges — Class 125 and Class 150 share the same bolt pattern, so one gasket covers both. A Class 300 flange is wider on a different bolt circle and takes a different gasket. Red rubber (SBR) suits water, brine, air and low-pressure service; for oil, fuel, solvents or acids ask for Buna, Viton, EPDM or non-asbestos.
Where a 12 in. goes. Municipal and industrial water mains, treatment plant and lift station discharge, fire service mains into buildings, cooling tower headers and large irrigation trunk lines. It carries the same twelve 1 in. bolts as the 10 in., but on a 17 in. bolt circle instead of 14-1/4 in. — so measure the circle, not just the hole count, if you are deciding between the two.
Flanging up a whole pump?The suction flange is normally a size or two bigger than the discharge, so a 12in rarely goes in on its own.
- 10in Full Face Flange Gasket — 16in OD, 12 bolt holes at 1in
- 8in Full Face Flange Gasket — 13-1/2in OD, 8 bolt holes at 7/8in
12in is the largest we hold as standard stock. Above that, or in a different thickness, oversize bore, Buna, Viton, EPDM or neoprene, we cut to print — call or text 561-414-1046 with your flange dimensions.
