PRODUCT DESCRIPTION

1288M66P04

  • Fluorocarbon Elastomer (FKM): Exceptional resistance to jet fuels, oils, hydraulic fluids, and most solvents.

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

  • Smooth Surface Finish: Minimizes friction and wear in reciprocating shaft applications.

  • FAA 8130‑3 Certified: Supplied with full trace paperwork for U.S. and European airworthiness compliance.


  • Provides a static seal between the pump cover and body in maintenance bays.

  • Acts as a barrier O‑ring in filter heads during fuel servicing operations.

  • Prevents oil leaks at rotating shaft interfaces in engine‑run test cells.

  • Seals duct flanges in air‑conditioning packs during ground and in‑flight conditioning.


  • How do I verify the correct O‑ring size before installation?

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

  • Is any lubricant required during installation?

A light coating of system-compatible fluid eases installation and prevents pinching.

  • What shelf life does the O‑ring have?

Stored in a cool, dark environment away from ozone sources, it maintains full performance for at least five years.
