HNBR FKM Hammer Union Seals 1-4 Inch for Oil and Gas Industry

HNBR and FKM Hammer Union Seals for 1-4 Inch Oilfield Connections

Royal Way® HNBR and FKM hammer union seals are offered for replacement enquiries covering 1, 2, 3 and 4 inch nominal union sizes. Identify the union figure, manufacturer and seal drawing before selecting the elastomer option for oilfield piping or service equipment.

For mixed-size maintenance orders, specify each seal as a separate line item with its compound, dimensions and assembly reference. HNBR and FKM designations identify material families; the selected formulation and complete union construction must suit the actual fluid and operating conditions.

Product Specification

1. Assembly Pressure: State the complete union working-pressure rating and service conditions. FIG 602, 1002 and 1502 are identification references, not standalone seal pressure ratings.

2. Compound Requirements: Include process fluids, additives and cleaning exposure in the HNBR or FKM enquiry. Confirm the specific compound rather than relying on a general rubber-family description.

3. Maintenance Fit: Check the seal profile, pocket condition and any reinforcement against the equipment drawing. Agree replacement inspection and assembly test requirements.

4. Size References: The original table retains the nominal union-size and material references. Confirm actual seal dimensions separately for each figure and union manufacturer.

5. Service Acceptance: Define temperature exposure, pressure cycles and any gas-service requirements for the intended assembly. Qualification must apply to the supplied compound and construction.

Organizing a Mixed-Size HNBR and FKM Replacement Order

List nominal union size, FIG designation, manufacturer and drawing revision for every replacement line. Include the seal dimensions and any brass or stainless anti-extrusion components shown on the approved drawing. A shared nominal size does not establish interchangeability.

Specify HNBR or FKM by the approved compound reference, nominal hardness and tolerance. Provide the operating fluid and cleaning sequence so each line can be reviewed against its own service conditions. Keep different compounds identified during receiving and storage.

For repeat maintenance supply, retain the approved drawing and sample reference with the order line. Agree dimensional inspection, material documentation and the required assembly acceptance checks before quantity production. The retained FIG 206 and related swivel references below require separate selection.
