Stage I Vapor Recovery Adaptors are installed in spill containment manholes on the vapor recovery riser pipe
from an underground gasoline storage tank. They mate with the vapor recovery elbow on the delivery transport truck when recovery
of gasoline vapors is required.
The OPW 61VSA Vapor Swivel Adaptor is a poppeted adaptor, designed to mate with a vapor recovery elbow, featuring
a top section that rotates with hose movement while the bottom section remains securely sealed to the 4-inch tank riser. The
61VSA is rated at 10 psi maximum working pressure.
