Our hydraulically operated vapor recovery adapters are
manufactured from 316L stainless steel investment castings and are electropolished for easy cleaning. The standard unit can be supplied with a 3” straight threaded female swivel outlet for mounting on a 3” clean-out nipple and one or two 2” NPT outlets to allow for both top and bottom vapor recovery. The adapter is closed in transit and opens consecutively with the tanks’ hydraulic internal valve using the existing hydraulic hand pump. The external hydraulic cylinder is completely isolated from the tanks’ lading. The main sealing surface is a Teflon® encapsulated O-Ring (Tef-O-Sil), which is compatible with most chemicals. The adapter is designed to be “Cleaned-In- Place” without removing the assembly from the tank trailers pipework. The unit can also double as an air-unloading device.
