This is 1/8 OD brass tube very nice tube BRAND NEW with a wall thickness of 0.36mm (0.014 inches) The great thing about this tubing that the next size up(5/32) fits the 1/8 inside it and this is the same for all the tubing by K & S.

All the tubing the size below fits inside each other.

This is for a 12" length posted same day as purchase next day delivery please check my feedback.
