Product Introduction
These FKM hammer union lip seals are specified for the actual union manufacturer, figure, nominal size and groove. Match the lip profile and backup arrangement to the original component drawing. Review the supplied compound against the fluid and operating conditions; complete-union documentation determines pressure and service acceptance.
Product Specification
Material Properties
FKM (fluorocarbon) is the material family listed for this lip seal. Specify the actual grade and hardness for crude oil, drilling-fluid formulation, additives, temperature and exposure duration. H2S, CO2 and decompression duty require particular compound qualification; the FKM name alone does not establish gas or chemical acceptance.

Material Comparison: FKM vs. NBR vs. HNBR
NBR: Review grade-specific fluid, temperature and mechanical requirements. Specify the compound grade and required qualification for the actual gas composition, pressure, temperature and decompression conditions.
HNBR: Confirm compound grade and required properties for actual duty. H2S, CO2, temperature and decompression acceptance require qualification for the supplied grade.
FKM: Review grade-specific compatibility, temperature limits and gas-exposure qualification rather than assuming universal chemical superiority or sour-gas acceptance.

FAQ
Question: Why is the lip design important for hammer union seals?
Answer: Match lip geometry and orientation to the original union drawing. Follow manufacturer requirements for groove condition, assembly and acceptance; lip design does not replace complete-union pressure qualification.
Question: Can I use FKM seals in H2S (Sour Gas) environments?
Answer: Provide gas composition, pressure, temperature and decompression conditions. Review the particular compound qualification and complete-union service class before acceptance.
Question: How do I identify which seal fits a Fig 1502 union?
Answer: Provide the actual manufacturer, Figure 1502 reference and nominal size, then verify seal dimensions, groove and backup arrangement against the original drawing. A nominal 2-inch label alone does not prove cross-brand interchangeability.
Question: What is the shelf life of FKM hammer union seals?
Answer: Follow the supplied compound’s storage and shelf-life instructions. Record batch and manufacture dates, protect from contamination, sunlight and ozone, and inspect before installation. Use the shelf-life limit stated for the supplied compound and batch.
Question: Are these seals compatible with acidizing fluids?
Answer: Provide acid formulation, concentration, inhibitors, temperature and exposure duration for review of the actual FKM grade. A generic chemical chart alone does not qualify the complete sealing configuration.
FKM Lip Seal Replacement: Nominal Size and Actual Groove
Use the nominal pipe size to identify the union, then use the original seal drawing to confirm the replacement geometry. Record seal diameter, axial dimensions, lip profile and backup arrangement against the manufacturer’s component reference. Keep Figure 206 entries and swivel repair kits in the related lists as separate order configurations. Agree compound grade, quantity and inspection requirements for each figure-and-size combination.
