Hammer Union Seals: NBR, HNBR and FKM Options for FIG 602, 1002 and 1502
This hammer union seal listing brings together NBR, HNBR and FKM material options for oilfield replacement enquiries. Select a specific compound and seal construction for the identified FIG 602, 1002 or 1502 union. Include the equipment manufacturer, connection size, seal drawing and service conditions with the request.
1. Assembly Pressure: State the complete union rating, maximum operating pressure and pressure-cycle requirements. FIG numbers identify union configurations and do not establish an independent pressure rating for a loose seal.
2. Material Review: Compare candidate NBR, HNBR and FKM compounds using the actual fluid composition, additives, cleaning agents and temperature conditions. A polymer family name alone does not qualify a compound for the application.
3. Installation Fit: Match the seal section and locating features to the union pocket. Use the equipment manufacturer’s maintenance instructions and define assembly inspection and test requirements after replacement.
4. Size and Construction: The original table below remains a reference for nominal sizes and material options. Specify the selected compound, nominal hardness and any brass or stainless anti-extrusion construction on the order drawing.
5. Qualification: Supply gas composition, pressure, temperature and decompression conditions when gas or sour service is involved. NBR, HNBR and FKM options each require their own applicable compound qualification.
Compare Union Seal Compounds by the Actual Service Specification
For a material comparison, send the same union drawing and operating specification with each candidate compound request. Include normal and peak temperatures, fluid exposure, pressure cycling and any required test method. This allows the options to be reviewed against a common set of requirements.
The listed 70–90 Shore A range represents hardness options. Define one nominal hardness and tolerance for the selected compound rather than treating the whole range as one replacement specification. Identify any anti-extrusion part separately, including material and whether it is included in the assembly.
Provide the FIG designation, union maker, nominal connection size and seal part number. The retained 1, 1-1/2, 2, 3 and 4 inch references need confirmation against the specific seal profile. For repeat orders, retain the approved drawing revision, compound identifier and inspection requirements.
