Chemical Resistant 2 1/2 Inch FKM Swab Cup for Sour Well Fluid Recovery Services

This 2-1/2 inch SV swab cup listing identifies an FKM compound option for application-specific well service. Use the nominal size and SV profile as identification references, then confirm the actual dimensions and mandrel interface. For chemical or sour-well conditions, provide the fluid or gas composition, pressure, temperature and decompression cycle. Compound-specific qualification is required before claiming suitability for H2S or CO2 service.

1. Temperature Selection: Provide continuous and peak temperatures, exposure duration and operating cycles for compound selection.
2. Chemical Selection: Identify acid type, concentration, inhibitors and other additives. Compatibility must be confirmed for the specific FKM grade.
3. Exposure Review: Specify the fluid or gas composition, pressure and exposure conditions. Check swelling and deterioration against agreed test requirements.
4. Assembly Fit: Confirm the SV profile, cup dimensions and mandrel interface for the required bore and fluid-load configuration.

Question: Why should I choose FKM over HNBR?
Answer: Compare specific compounds against the actual medium, temperature and mechanical conditions. Neither FKM nor HNBR is universally preferable for every acid or sour-gas service.

Question: Does the FKM material affect the flexibility of the SV design?
Answer: Lip flexibility depends on compound, hardness, profile and temperature. Confirm the selected cup against its installation and operating requirements.

Question: Is this product suitable for CO2 injection wells?
Answer: CO2 service requires compound-specific review of gas composition, pressure, temperature and decompression conditions. FKM identity alone does not establish suitability.
