Durable Hammer Union Seal Designed for Ring Seals and Weco Seals Suitable for Fig206 602 607 1002 1003 and 1502 Applications

SHQN hammer union seals are replacement sealing components for identified flowline connections used in cementing, manifolds and drilling service. Match the actual union figure, nominal size, manufacturer reference, seal groove and construction before ordering. Working pressure and temperature limits depend on the complete union assembly and selected compound; a replacement ring does not establish structural integrity or a universal pressure rating.

To meet different wellhead conditions, we offer various high-performance materials:

• NBR (Buna-N): Review the selected compound against actual oil, additives and hydraulic-fluid formulation
• HNBR (Hydrogenated Nitrile): Review compound-specific temperature, fluid and mechanical-duty requirements
• FKM: Review actual chemical formulation and temperature; sour-service suitability requires specific qualification
• Anti-Extrusion Rings: Confirm backup-ring material, profile and retained or separate construction from the actual union drawing
