LC501 Series

Design Features

High Temperature

Designed for high temperature environmental control and engine bleed air applications. Couplings of CRES material using high temperature seals are suitable for 650°F operation.

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.

Quick Disconnect

Quick disconnect action of the latch simplifies and facilitates assembly and removal by one hand.

Easily Inspected

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

Flexible

Axial adjustment is 1/4" nominal; angular misalignment is ±4° for full coupling.

Lightning Protection

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.

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".
