Rubber Union Seals with Brass or Stainless Steel Anti-Extrusion for Durability

Rubber Union Replacement Seals with Brass or Stainless Steel Backing Options

Matching rubber and backing construction for repeat orders

For repeat replacement orders, keep the approved rubber profile and metal backing specification together as one part reference. Record the union manufacturer, figure, nominal size and drawing revision, then confirm the NBR, HNBR or FKM compound and hardness. Specify brass or stainless steel grade and ring dimensions when backing is required. Compare the supplied samples with the drawing rather than identifying a seal by color alone. Agree batch labels and inspection requirements before production; service life depends on the actual assembly and operating conditions.
