PRODUCT DESCRIPTION

D2127400720400

  • Fluorocarbon Elastomer (FKM): Outstanding compatibility with jet fuels, hydraulic fluids, and oils.

  • Low Compression Set: Maintains sealing force after thousands of thermal and pressure cycles.

  • Smooth Surface Finish: Minimizes friction and wear on reciprocating or rotating shafts.

  • EASA Form 1 Certified: Supplied with full trace paperwork for European airworthiness compliance.


  • Seals between the pump housing and cover in maintenance bays.

  • Provides static sealing in fuel metering units on the ground and in‑flight.

  • Maintains leak‑proof joints in gear‑bay plumbing during taxi and landing.

  • Prevents leaks in air‑conditioning pack connections under bleed‑air pressure.


  • How do I verify the correct seal size before installation?

Measure inner diameter and cross‑section thickness with calipers and compare to the OEM groove specifications.

  • Can this seal be used on dynamic shafts?

Yes, its low‑friction finish and FKM compound suit low‑ to medium‑speed rotary applications up to 500 rpm.

  • Can the seal be reused after removal?

For best reliability, always replace with a new seal. Reusing can compromise integrity due to the compression set.
