About this product
The 1904135043 is a service seal supplied with EASA Form-1 traceability. It is a precision-made sealing element intended to fit the OEM gland, groove, or cover called out in the aircraft IPC/AMM. In service, the seal prevents fluid or air leakage, keeps contaminants out of equipment housings, and restores the original clearance and sealing function after maintenance or overhaul.

PRODUCT DESCRIPTION

1904135043

  • EASA Form-1 certified: Supplied with traceable paperwork for inclusion in certified maintenance records.

  • OEM form-fit: Manufactured to the dimensions called out, so it installs without modification.

  • Aerospace-grade compound: Made from the elastomer or material specified on the Form-1 for aircraft use.

  • Tight dimensional control: Precision molding ensures even compression and reliable sealing.


  • Seals rod and piston glands in hydraulic actuators during actuator overhaul and routine maintenance.

  • Provides a leak barrier in pump and gearbox covers to retain oil and prevent contamination during bench tests.

  • Seals fuel-system service ports and couplings where the AMM specifies this OEM part.

  • Forms a pressure-tight joint on pneumatic valves and manifolds in ECS and pressurization systems.


  • Will it fit my unit?

Use only where the aircraft IPC/AMM or OEM parts list specifies 1904135043.

  • How should I inspect the seal before fitting?

Check for cuts, nicks, flat spots, discoloration, or contamination, and verify the Form-1 and part number match the job card.

  • Can I reuse the seal after removal?

Generally, seals are replaced when disturbed. Reuse only if the AMM explicitly permits it and the seal passes a strict inspection with no permanent set.
