Civacon specializes in products for petroleum, chemical and dry bulk cargo tanks that help safeguard against spills, overfills, and fugitive emissions: access ports, manholes, weld rings, hatches, fill covers, swing check valves, pressure vacuum hatches, pressure relief valves, vapor valves, bottom loading equipment, delivery elbows, overfill detection devices, and vapor recovery adaptors


Our ROMLinkTM "Plug-N-LoadTM" wiring system eliminates the slow, messy, and at times unreliable cut, strip and crimp method of wiring.


CivaControlTM Air Systems bring together the control of Compartment Vents, Vapor Recovery Valves, Internal Valves, Overfill Protection and Vehicle Drive Away systems

Opti-Link Socket

The Opti-Link socket is API-compatible, allowing it to interface with any optic control monitor plugs.

Civacon’s Metro Overfill Monitor

Civacon’s Metro Overfill Detection System has been designed to provide petroleum tankers with seamless integrated communication and diagnostics capabilities. This is possible because Metro’s components feature a unique digital address that allows them to communicate through Civacon’s hassle-free Plug-N-LoadTM wiring system.

ROMLinkTM Body Harness

The ROMLinkTM "Plug-N-LoadTM" body harness is available for multi-compartment trailers.

Harness extensions are also available for many trailer options.
