Sub-Slab Vapor Implant Brass
The hollow vapor implant is designed to be installed into a 16 mm diameter hole through a concrete slab. It protrudes out the bottom of the slab to allow vapors to be drawn up through the middle of it. The pins can be extracted and reused.
The pins are inserted into position using a silicone sleeve. This forms a seal between the slab and soil vapor implant. A push on cap keeps the pin sealed when not in use.
