Designed for a precise, drop-in fit into standard 4-inch Weco-style hammer unions—including standard Figure 602, 1002, and 1502 profiles—this high-performance seal acts as an impenetrable pressure barrier against volatile, high-volume, and corrosive fluids.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eA critical feature of this extra-large-bore seal is its \u003cb data-path-to-node=\"5\" data-index-in-node=\"56\"\u003eindustry-standard Green color-coding\u003c\/b\u003e. In fast-paced, high-stress field operations involving massive 4-inch flowlines, visually distinguishing between elastomer materials is paramount for site safety. The bright green color allows operators and inventory managers to instantly identify the seal as severe-service Viton (FKM), entirely preventing accidental swapping with standard black Buna-N seals in aggressive environments where inferior materials would rapidly degrade and lead to catastrophic leaks.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eMolded from heavy-duty \u003cb data-path-to-node=\"6\" data-index-in-node=\"23\"\u003eViton® (Fluorocarbon \/ FKM)\u003c\/b\u003e, this seal provides unparalleled resistance to elevated temperatures, synthetic drilling muds, sour gas (H2S), and aggressive completion chemicals. Combined with a highly efficient pressure-energized lip design that actively expands against the union’s mating surfaces as line pressure increases, this green Viton seal guarantees a blowout-proof connection under the most demanding, large-scale well-servicing conditions.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
