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.

RAPCO OEM Replacement...

Modern reciprocating-engine aircraft (especially large and high-performance ones) use electrically operated auxiliary fuel  boost and transfer pumps  to keep fuel moving toward the aircraft engine or move fuel between tanks to balance aircraft weight. Centrifugal boost pumps,  electric motor driven,  are the most common type and  are used to supply,back up the engine-driven fuel pump or transfer fuel between tanks if the aircraft is so designed. They are  most frequently  submerged in the fuel tank or located just outside of the bottom of the tank with the inlet of the pump extending into the tank. Cartridge/canister or in-tank mounted pumps supply fuel to the aircraft engine while reverse flow through the pump is prevented by check valves. The cartridge/canister design allows removal of the pump cartridge without draining the fuel tank. If the pump is mounted outside the tank, a pump removal valve is typically installed so the pump can be removed without draining the fuel tank.

The RAPCO FAA-PMA approved pumps are offered as direct replacements of the respective pumps by OEMs  such as PARKER AIRBORNE or DUKES (please refer to their separate product presentations).
