A30-CIR is a screw threaded fuel cap the will fit almost flush to a skin, with the riveted flange on an adjacent tank or the back of a 'wet' skin.
This was designed to be fitted after painting, reducing the likelyhood of dirt/dust in the cap and the cost of masking/finishing operations. It is available with a locking or non locking cap. A30 L-CIR (05-06838) Locking A30 S-CIR (05-06837) Non-Locking |
I was pleasantly surprised to see that this thread is the same as 05-01056 flange that I originally purchased with the bayonet fuel cap and filler neck. I need a lower profile cap and this threads into the flange that is already glassed into the tank.
