FKM and Nitrile Union Seals — Equipment Fit and Gas-Service Review

Hammer Union seals:

For replacement enquiries referencing WECO, FMC or Kemper hardware, provide the exact equipment model, union figure and groove drawing. Review each mating design independently. Specify gas composition, H2S and CO2 levels, temperature, pressure and decompression cycles for gas-service material selection.
Confirm ring profile, orientation, groove dimensions and installation procedure with the hardware specification. Hammer-operated and hammerless connections need separate fit review.
Identify the exact figure and nominal size for each lip-ring or O-ring enquiry. Figures 2202, 1004, 1502, 2002, 602 and 1002 do not establish shared seal geometry without the corresponding drawing.
NBR, FKM and HNBR options require exact compound identification and compatibility evidence. Sour-gas suitability cannot be inferred from the polymer name. Brass or stainless steel backup designs need dimensional approval; PTFE alternatives require separate grade and construction review. Agree assembly acceptance criteria instead of assuming leak-free performance.
