Acro engines oil pipe fitting

Postby G-CIZS » Fri Jan 07, 2022 8:01 pm

Good evening,

Does anybody know the make/ name of the oil fittings used by Barry Smith on the oil tank and Ball valve pipe fittings.
We have one that the olive has disintegrated on and before looking to change it all i thought it was worth asking.

Many thanks

Hi Toby,

Do you mean the oil change-over valve to sump extension? The colour of the fitting suggest it is probably a standard automotive part. Does it match the size of the fittings on the oil cooler? They are 1/2” BSP.

Yes it is on the pipe to the sump extension. There is also 3 on the ball valve, one on the oil pump inlet and one from the breather tank to sump pipe.

I agree by colour and Barrys belief in affordable aerobatics that it would be a commercial low cost part.
It is close to a power steering fitting but they seem to have O rings rather than the plastic tip. Also they lack the compression Olive which i assume grips the pipe so the plastic tip is loaded in as the olive would never seal as its split.

Fingers crossed somebody will know or I will be reinventing the wheel!!
