14J34 Series

Design Features

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.

Easily Inspected

Visual inspection from a distance provides positive indication that the closure is fully engaged and securely locked.

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 1/4" angular misalignment is ±4° for full couplings.

Meets Military/Commercial Requirements

Coupling design conforms to and has been qualified to all applicable military and commercial specification requirements for flexible fuel couplings, environmental control systems or potable water systems.

Lightning

Protection is provided to at least 1500 amperes when tested per MIL-STD-1757A, 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.

Product Notes

1. Coupling flanges and seals are not furnished with these assemblies and, for clarity, are shown in phantom outline. Seal material is selected and seals are separately procured by user. For additional information see notes 1 & 2 under "Ordering Information".
2. The 14C34-(SIZE)A Clam-shell Assembly material is 2024-T851 aluminum alloy or equivalent, anodized, dyed magenta. Latch pawls, hinges, rivets, latch springs: 300 series CRES, passivated. Bonding springs: beryllium copper wire, tin coated. Safety strap: nylon.
   The 14C34-(SIZE)C Clam-shell Assembly material is 300 series CRES, passivated. Latch pawls, hinges, rivets, latch springs: 300 series CRES passivated. Bonding springs: beryllium copper wire, tin coated. Safety strap: nylon.
3. The 14J34-(SIZE)C is the same as the14J02 with the addition of the safety device.
4. The coupling assembly has been fully qualified to Aerospace Standard AS1650 and meets the performance requirements of MIL-C-22263.
5. Coupling assembly weights shown in table below do not include flanges and seals.
6. Consult factory for pressure ratings for particular applications.
   Temperature rating -65°F to +450°F.
   example: Lockheed Martin C7551
