21J02 Series Flexible Coupling
21J02 Series
Locks Automatically: Clam-shell closure locks automatically when two halves are snapped together and cannot disengage accidentally since all three latch pawls must be lifted simultaneously to disengage the latch.
Super Lightweight: The complete coupling system has been designed for a minimum weight. Only welded style flanges are available.
High Strength Coupling design: conforms to and has been qualified to all applicable military specification requirements for flexible fuel coupling systems for service at pressures of:
400 PSIG (operating) @ 300Ā°F sizes -08 thru 14
200 PSIG (operating) @ 300Ā°F size -16
125 PSIG (operating) @ 120Ā°F -20 thru -64
Latch Pawl Design: The latch pawl design allows operation without damage to CBR gloves and allows operation while wearing artic gloves.
Safety Device: The safety device is provided to help prevent mis-installation. The safety device cannot be engaged unless the coupling has been completely closed.
Flexible: Axial adjustment is 1/4" nominal; angular misalignment is Ā±4Ā° for full coupling.
Lightning: Protection is provided to at least 1500 amperes when tested in accordance with MIL-STD-1757 test method T03 using current component B waveshape.
Self Bonding: Electrical bonding to class "S" of MIL-B-5087B is automatically provided when the coupling is assembled.
