It combines one‑way pressure relief with two‑direction venting so tanks neither overpressurize nor collapse when fuel is dispensed. Constructed from corrosion‑resistant materials and fitted with an internal gasket and spring, the cap offers reliable sealing on rough roads and in outdoor work environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cap keep a diesel transfer tank safe on the road?\u003c\/h3\u003e\n\u003cp\u003eThe cap vents excess internal pressure as the tank warms, releasing vapors before they can overstress the tank shell or fittings.
