Pressure Refuel Caps SKU:...
Filler opening caps are parts basically circular in shape, designed to cover or seal the filler-neck or inlet opening of a fuel tank, radiator, oil reservoir, liquid storage tank or the like. They are either permanently attached or provided with a means of removal and replacement.
Pressure refuel caps are used to lock, seal, and vent the pressure refuel port for an aircraft fuel tank. Pressure refueling allows for single point refueling on larger aircraft and can be used with all aircraft fuels. To fuel the aircraft, the caps are manually actuated by pressing down on the handle, which will vent and unlock the cap for removal by twisting. The cap remains attached to the aircraft by a lanyard. Once refueling is complete, the cap is inserted back onto the adapter and twisted until locked into place, which effectively reseals the pressure refuel port.
Pressure refuel caps are offered by different manufacturers such as Parker Aerospace, Eaton Coporation and others. They are designed in accordance with military specification MIL-C-8605B (for technical requirements) and MS29526-2(for envelope requirements).
Those from Parker Aerospace are 4.5 inches diameter, with an indexing feature and they fit into a 2.5-inch pressure refuel adapter per military specification MS24484. Their main features include an aluminum base and handle, a fluorosilicone O-ring seal, and antisparking brass chain lanyard (per industry standard RR-C-271) with a plastic tubing cover and corrosion resistant steel hooks. Lanyards can also be fabricated with corrosion-resistant steel or flexible plastic and fuel resistant tubing. Optional features are also available such as key lock, ventilation, hinge, visual fluid level indicator, dust cover easy-lift handle and contoured adapter.
