Exactly the part I was looking for. As this restrictor fitting is hard to find, I was glad to see that Aircraft Spruce stock it. On our Cherokee 180, this restrictor fitting goes in the oil pressure line that runs from the engine to the oil pressure gauge in the cockpit.

Q: Is the flared end a -3 or -4? Looks like -3, but your description is modified -4.

The 05-11908 is an AN823-4 fitting, but has a .040" restrictor bushing on the pipe thread end of the fitting. The flared thread end is a -4, and pipe thread end is 1/8" NPT, just like a standard AN823-4 fitting.

Q: Is there an R or any other engravings/markings on the part?

There is a marking D on the fitting.

Q: Is this a steel fitting?

Yes, the fitting itself is steel.

Q: Will this fitting also work for manifold pressure?

Yes, per the vendor.

Q: A restrictor fitting will lengthen the time before exhausting oil to about 1 minute.

Thank you for your comment.
