Utica-Dunkirk 43300977 Push Nipple 318172-701 or visible "bulging" and leakingThe Utica Dunkirk 43300977 Push Nipple is a heavy duty, cast iron 4 inch push nipple engineered specifically for sealing the cast iron sections of Dunkirk D249 and ESC Series IV boilers. Unlike standard rubber gaskets or steel nipples that can fail under extreme thermal cycling, this machined cast iron nipple shares the same expansion coefficient as the boiler sections themselves. This ensures a leak proof boiler seal that maintains structural
