■ ■ ■ ■ ■ ■■ ■
Meets or exceeds the requirements of MIL-C-25427A and ARP 1709, C lass 1000. Streamlined flowpath provides unsurpassed flow. (e.g. -08 size: .6 PSID at 5 GPM) Design minimizes air inclusion and fluid loss. Nipple poppet seal also serves as the interface seal, eliminating spillage when connected or disconnected. O-Rings are not exposed. This reduces contamination and eliminates the problem of shearing of exposed O-Rings. Simple latching mechanism increases reliability, y et provides a smooth, positive latch eliminating partially-locked positions. No snap rings are used. Relief valve available in nipple half. Designed to minimize weight, envelope size, and the travel length required to connect.
The exposed interface sealing surface in the coupler is recessed to protect it, and to prevent it from being scratched. The nipple poppet/interface seal is enclosed and protected. Since the outside diameter of the nipple is not a sealing surface, the problem of leaks caused by scratches on this surface is eliminated.
