MARS brass and steel flanges

MARS flanges are made from close grained, high tensile iron. Our method of core manufacture produces a casting that’s smooth and clean inside and out, free of imperfections.

The threads are precision tapped to ABS standards, each opening chamfered for easier assembly. When installed, they take up easily and draw tight.

On your next order, specify MARS flanges for optimum performance and easier installation.

NOTE: MARS flanges conform to ANSI B16.1 Class 125 and 250 Standards. ANSI B 16.5 Class 150 and 300 also available.
