Designed to fit precisely into standard 3-inch Weco-style hammer unions, including the widely used Figure 1502, this heavy-duty elastomer seal ring acts as the primary pressure barrier between the male and female subs, preventing fluid bypass and protecting the integrity of your large-bore flow control system.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eConstructed from high-grade \u003cb data-path-to-node=\"5\" data-index-in-node=\"28\"\u003eBuna-N (Nitrile \/ NBR)\u003c\/b\u003e, this seal is the reliable industry standard for general-purpose oilfield applications. Buna-N offers exceptional resistance to petroleum-based oils, synthetic lubricants, water, and abrasive drilling muds. The seal features a highly effective lip design that is pressure-energized; as internal line pressure increases, the lips of the seal are forced outward against the metal mating surfaces of the union, tightening the seal and preventing leaks even under the severe vibration and high flow rates common in 3-inch lines.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eIdeal for standard service environments, this 3\" hammer union seal provides excellent extrusion resistance and durability, ensuring your flowline equipment operates safely and efficiently during high-capacity cementing, fracturing, circulating, and well-testing operations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
