Parker Aerospace’s 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. Parker’s pressure refuel cap is designed in accordance with military specification MIL-C-8605B (for technical requirements) and MS29526-2 (for envelope requirements). The cap can be used with all aircraft fuels, and also features an aluminum base and handle, a fluorosilicone O-ring seal, and an anti-sparking 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.

Parker Aerospace pressure refuel caps are 4.5 inches in diameter, with a refuel coupling indexing feature. They fit into a 2.5 inch pressure refuel adapter per military specification MS24484. 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.

Parker Aerospace offers over 3,000 active, certified parts, including market-leading fuel caps and adapters. From flame arrestors to fuel caps, Parker Aerospace components are meticulously designed to meet the highest military and commercial specifications and standards.  Our on-site development, qualification, and test capabilities are just further advantages to partnering with Parker.
