Vapor Pin® Sieve– Brass

Sieves are attached to extensions or the Vapor pin^® sampling device itself to allow air to enter from the sides. They are used to avoid clogging the pin or extension when samples are collected beneath the slab. Sieves are very robust and can be hammered into the gravel bed or concrete debris beneath the slab. Sieves also allow the Vapor Pin^® devices and extensions to be tightened with a wrench.
