7" hammer union seal with stainless-steel anti-extrusion ring, supplied in 85 Shore A NBR for compatible oilfield flowline and pressure-service union equipment.

Construction

  • NBR (Buna-N): general oilfield service with petroleum oils and compatible water-based fluids.
  • Stainless-steel anti-extrusion ring: commonly selected where compatible corrosive liquids or gases make stainless steel preferable to brass.

Ordering

Selected hammer union seals are available with brass or stainless steel anti-extrusion rings. Material, hardness, and insert type should be selected according to pressure rating, temperature, fluid media, and service conditions.
