Hammer union replacement seals must match the connection design rather than nominal pipe size alone. This listing focuses on clarifying line-pipe size references in a seal enquiry: provide the union manufacturer, figure and part number or drawing together with the nominal connection size. Composite insert arrangements apply only where specified by that design.
The ring is a sealing component of the union hardware, rather than a complete threaded or welded connection. Confirm the required lip or O-ring profile, actual dimensions, groove arrangement and any backing component. Figure references such as 602, 1002, 1502, 2002 and 2202 require individual matching review.
Catalogue references include 1, 2, 3, 4 and 5-inch nominal connections. Confirm availability for the exact union and supply the actual seal dimensions; a line-pipe size does not establish the ring outside diameter or cross-section.
Specify the exact NBR/Buna, FKM or HNBR compound, Shore A hardness and tolerance. Review the fluid and operating temperature with the selected compound. The older 1-to-4-inch material reference does not define coverage for every figure or establish a material rating.
Application: replacement sealing at specified oilfield hose or pipe union connections. Pressure and test limits belong to the complete rated assembly under its service conditions. Sour-gas suitability requires material and equipment-specific qualification. Inspect grooves and mating surfaces using the equipment procedure, and retain the part drawing and compound identity for repeat orders.
