Oil rig help!

[TF Leary]

i have a small perk tech oil rig. I need to buy a new nail and dome. I measured the section of the piece where the dome would slide down onto and it measures 12mm...with that being known, could someone tell me what size nail I would need or can that not be figured by knowing the outside diameter? The reason I ask is because the caliper, or whatever theat tool is called is a little plastic one and won't give me an accurate measurement of the inside diameter! Thx....

Have not heard of 12 mm. Typical sizes are 10-14-18mm

Find something else that fits inside the dome pretty well, take it out and measure it's outside diameter. Something tapered would be good.
