Black NBR hammer union seal ring for specified union hardware
Hammer Union Seal
This black NBR hammer union seal listing focuses on identification and repeat-order matching. Specify the exact union manufacturer, figure number, nominal connection size and seal part number or drawing; black color alone does not identify the rubber compound or profile.
Buna/NBR, FKM and HNBR compounds, unreinforced lip seals, brass-backed rings and stainless-backed rings are separate configurations. PTFE parts require their own design review. Confirm the selected profile, dimensions and backing against the actual union hardware; catalogue size families do not establish that one seal fits every hammer union.
For black NBR enquiries, provide the fluid, temperature, pressure conditions and required Shore A hardness. Review compound compatibility rather than assuming that every black ring has the same oil resistance or service limits.
Hammer unions use mating ends and a hammer nut to assemble the connection. The required seal profile depends on the equipment design. Inspect the sealing surfaces and groove using the manufacturer's service procedure before replacement; damaged hardware is not corrected by changing a rubber ring.
For repeat orders, retain the approved drawing revision, compound specification and packing label. Pressure limits are confirmed for the complete rated union assembly and operating conditions; a rubber seal has no independent universal pressure rating. Production is managed under an ISO 9001 quality management system; agree any material or inspection documents required for the order.
