Product Introduction
1. Operating Envelope
FKM is specified at the boundary where other elastomers stop being useful. Heat above 120°C, contact with aromatic solvents, or prolonged immersion in jet fuel will harden, swell, or crack NBR and CR - yet an FKM rubber grommet retains its dimensions, flexibility, and clamping force. The fluorine atoms along the polymer chain create an inert barrier that few chemicals can attack, which is why the material appears in fuel systems, chemical plants, and engine bays worldwide.
2. Why Designers Choose It
- Survives fuels, oils, and solvents that cause competing rubbers to swell 20%+
- Keeps sealing at 200°C continuously - no embrittlement, no compression set
- Blocks gas permeation, making it suitable for vacuum and pressurized enclosures
- Resists ozone and UV, so exterior or under-hood placement is safe
- Bonds well to metal inserts and engineering plastics for over-molded assemblies
- Predictable long-term behavior - decades of field data in automotive and aerospace
3. Industries & Installations
- Diesel common-rail injectors, fuel pumps and EGR cooler wiring
- Aircraft fuel cells, engine pylon harnesses and avionics bay penetrations
- Petrochemical refinery instrumentation, analyzer sheds and valve actuators
- EV battery pack high-voltage entries and thermal-management fluid lines
- CIP (clean-in-place) food machinery where caustic cleaners are used
- Marine diesel engines, fuel manifolds and below-deck electrical boxes
- Defense ground-vehicle electronics exposed to fuel, oil and battlefield heat
4. Tailoring Options
- Any ID, OD, gland width, and section from your 2D print, 3D model, or physical sample
- Durometer tuned: 50A for easy assembly, 70A general, 90A for high pressure
- Grade selection: standard bisphenol-cured, low-temp FK, high-fluorine, peroxide
- Color: black, brown, green, or custom match for coding or aesthetics
- Geometry: blind, split for retrofit, multi-bore, stepped shoulder, thin-wall
- Post-mold: slit, notch, trim flash, bond to metal ring, bag & label per SKU
5. Production & Conformance
- Molding method chosen per part: compression for simple/low-volume, transfer for intricate, injection for high-volume precision
- Tool room in-house: design, machining, texture and first-shot sampling
- Every lot checked for ID/OD, durometer, visual defects, and flash
- Raw polymer lot numbers tracked through to shipped cartons
- Certificates of conformance, material data, and immersion test reports available
