The car's on the road so I'm back on other projects.
Does anyone know where I can get a square section O ring 1/8th inch section, 2.25 inches I.D.
It's for an internal seal in the fuel injection pump on the Bombardier engine for the Auster

for a plane engine that looks rather robust, built like a lathe really

Hav you tried the square o-ring shop?

seriously though, a very very long shot ... take a look at oil filters - it does sound like the sealing ring on those could be the right size ....

I should have one knocking around somewhere so can measure when I get home and if I remember.

Square section O rings are pretty difficult to find. Can you not use a round standard round section? The normal round O rings are designed to go into a square housing.

Found some for you

Square O rings

It could also be worth giving the IWM at Duxford a call, see if you can get put through to the maintenance section - find out where they get their o-rings and bits from.....

Cheers

If all else fails try brake caliper seals, I've just measured some I have, which are 1/8" square, but only 2 1/8" id.

Try giving Pirtec (Hydralic hose company a call ) they may have the square section rubber that you cut to your required radius and then supperglue the ends together.

Edited to add I think its called 'O ring Cord'

If not let me know and a freind may have some on his VAN

Hi

Scary stuff !!!!!

Parts will be listed in the OEM's IPC or CMM. Sourcing unapproved parts will, if declared, void the C of A / ARC and if not possibly comprimise the safety of the aircraft, crew and public.

Not advised.

Regards Mick

If my contact at Duxford IWM comes up with anything it will be C.A.A. approved .

Hi

EASA approved I hope,

Regards Mick
