Designed for a precise, drop-in fit into 2-inch Weco-style hammer unions, including the widely used Figure 1502, this high-performance seal acts as the ultimate pressure barrier against abrasive, high-temperature, and chemically aggressive fluids.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThe defining characteristic of this seal is its \u003cb data-path-to-node=\"5\" data-index-in-node=\"48\"\u003eHNBR construction\u003c\/b\u003e. Through the hydrogenation process, standard Nitrile is upgraded to provide vastly superior mechanical strength, excellent abrasion resistance, and enhanced thermal stability. This makes the HNBR seal highly resilient against synthetic oil-based drilling muds, harsh completion fluids, and elevated temperatures. Furthermore, HNBR provides excellent resistance to sour gas (H2S), making it an ideal choice for moderate sour service applications where maintaining a blowout-proof connection is critical.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eFeaturing a pressure-energized lip design, the seal utilizes internal flowline pressure to actively push the elastomer lips outward against the union’s mating surfaces.
