HNBR Hammer Union Seals for 2, 3 and 4 Inch Nominal Connections
This HNBR hammer union seal listing focuses on replacement enquiries for 2, 3 and 4 inch nominal oil and gas connections. Confirm the union manufacturer, FIG designation and actual seal profile for each size. Specify the HNBR compound and required service qualification with the equipment drawing.
Product Specification
1. Pressure Requirements: Supply the rating of the complete union assembly and its maximum operating conditions. Nominal connection size and FIG designation do not provide an independent seal pressure rating.
2. HNBR Compound: State the process-fluid composition, cleaning agents and temperature conditions. HNBR naming alone does not establish chemical compatibility or sour-service qualification.
3. Installation Matching: Verify the seal pocket and sealing faces against the equipment drawing. Use the union manufacturer’s replacement procedure and agree the assembly inspection and test requirements.
4. Size References: The table below retains multiple union figures and rubber options. Select the HNBR part for the specified 2, 3 or 4 inch assembly and identify any brass or stainless anti-extrusion construction.
5. Service Qualification: Gas composition, pressure, temperature and decompression conditions must be supplied where gas service is required. Review documentation and tests for the exact HNBR compound and selected assembly.
Match HNBR Seals to the Correct Figure and Section Profile
Separate each 2, 3 or 4 inch replacement request by union maker, FIG number and seal part number. Provide a profile drawing with dimensions and tolerances. Confirm the required anti-extrusion part and whether the quotation includes that component or only the elastomer.
The retained FIG 206 entries include AS568-228, AS568-236 and AS568-346 references. Check those original references against the specific FIG 206 gland drawing before use. They do not identify the seal profile for FIG 602, 1002 or 1502 connections.
Specify one nominal Shore A hardness and tolerance within the listed 70–90 Shore A options. Include fluid exposure, operating temperatures and any gas qualification requirements. For repeat orders, retain the approved HNBR compound identifier and drawing revision for each size.
