    Tank Vent Valve (threaded, NPTF)

    Product description

    Tank Vent Valve (threaded, National Pipe Thread Female)


    • Machined Aluminium
    • Yellow Polymer Valve
    • Tank vent valves are designed to direct vapours generated during the diurnal cycle. Vent lines from TVVs generally run to carbon canisters. Properly installed, TVVs help protect canisters from liquid fuel.
    • Perko's TVVs are sometimes referred to as rollover valves (since they offer rollover protection) and as grade vent valves. They also include a over-pressure relief feature.
    • Mounting options for tank mounted ICVs include flanged (for plastic tanks), threaded (for metal tanks) and swivel (for both plastic and metal tanks).
    • Flanged valves match the SAE 5-bolt level sender flange. Gasket is not included.
    • Threaded valves mount with a 1" NPTF thread.
    • Swivel valves include valves, valve housing, o-ring, snap ring and tank insert.
    • Internally mounted versions are available for both plastic and metal tanks on a custom basis.
