Designed for a seamless fit into standard 2-inch Weco-style hammer unions (such as the widely used Figure 1502), this composite seal ring provides superior protection against fluid bypass and seal blowout in demanding oilfield environments.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThe foundation of this seal is molded from high-grade \u003cb data-path-to-node=\"5\" data-index-in-node=\"54\"\u003eBuna-N (Nitrile \/ NBR)\u003c\/b\u003e, providing excellent resistance to petroleum-based fluids, water, and abrasive drilling muds.

During extreme pressure spikes and high-velocity flow, the softer rubber lip can be pushed into the union's clearance gap. The brass backup ring acts as a structural reinforcement, effectively blocking the elastomer from extruding and ensuring the pressure-energized lip maintains a tight, dynamic seal against the metal mating surfaces.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eAdditionally, the brass construction offers a non-sparking metallic option, making it an excellent choice for environments where safety and blowout prevention are paramount.
