High-Performance FKM NBR HNBR Hammer Union Seal for Oilfield and Industrial Applications
FKM NBR HNBR Hammer Union Seal Compound Selection
Shanghai Qinuo offers hammer union replacement-seal enquiries in FKM, NBR and HNBR. Choose a specific compound against the fluid, temperature and pressure-cycle requirements while retaining the correct union seal geometry. Changing the polymer family does not by itself establish an equivalent replacement or a service rating.
Product Specification
1. Pressure specification: Provide working pressure, transient peaks, temperature and pressure direction. The complete union assembly and selected seal design require qualification; a figure designation is not a standalone seal pressure rating.
2. Compound selection: Provide fluid composition, additives, cleaning chemicals and exposure duration. Review NBR, HNBR or FKM compound data against those conditions; polymer family alone does not establish chemical or sour-service suitability.
3. Installation fit: Confirm seal dimensions, lip orientation, mating surfaces and any brass or stainless steel backup ring against the equipment drawing. Follow the assembly installation procedure.
4. OEM dimensions: Send seal OD, ID, axial height, section profile and dimensional tolerances, together with nominal union size and figure. Include insert geometry and hardness where applicable.
5. Inspection requirements: Agree dimensional, material and leakage-test acceptance criteria for the selected design. Verify the complete assembly before service; no blanket pressure or leakage guarantee is implied.
Comparing FKM, NBR and HNBR for a Union Seal Order
For a compound comparison, keep the union figure, nominal size and seal drawing fixed. Specify fluid formulation and additives, continuous and peak temperature, pressure cycles and exposure duration. Include any cleaning fluids and gas decompression conditions so that the selected compound can be reviewed for the actual application.
Request compound identification, specified hardness and relevant test data with the quotation. Buna is an NBR designation and HSN is used for HNBR in the existing selection list. Color and polymer name alone do not establish fluid compatibility, sour-service qualification or compression-set performance.
Confirm seal OD, ID, height and lip section, plus any brass or stainless steel backup-ring dimensions. Compare quotations by the same drawing revision, compound requirements, quantity and inspection criteria. Manufacturing uses an ISO 9001 quality management system; any application-specific qualification must be agreed for the selected seal and assembly.
