Which is thinner a 30G or 27G1/2 syringe plunger?
Answers:
30 G is smaller- 1/2 is all along the needle Source(s): RN
The gauge of a syringe is used to designate the size of the lumen.
The higher the gauge number, the smaller the lumen of the needle.
Example:
10 G (largest) ----->27 G----> 30 G---> 33 G (smallest)

30G
When you are speaking of needle gauges, you are looking at the bottom part of a fraction, so it is really 1/30 or 1/27. Thus, the bigger the number, the smaller the syringe. The 1/2 refers to the length of the needle.
27G1/2
