parts

In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, 10−6), parts-per-billion (ppb, 10−9), parts-per-trillion (ppt, 10−12) and parts-per-quadrillion (ppq, 10−15). This notation is not part of the International System of Units (SI) system and its meaning is ambiguous.

    2 part reducing sets 10mm to 15mm??

    Do any of you guys use this type of reducer? It doesn’t have an olive and the bottom part of the brass compresses onto the pipe by the looks of it and the top is removable. I haven’t used them before tbh. I can only seem to find the 3 part versions by me.
