Product Data Sheet
Conductive Composite
Connector Covers 4270 Series are permanently volume conductive and free of carbon
black particulate. The Connector Covers 4270 Series do not leave black marks and are
more suited to clean situations. Meets the requirements of NASM5501 31/32.
Noncorrosive
Connector Covers 4270 Series are noncorrosive and produce no visible corrosion
when tested to Federal Test Method 101C using Kovar test plates.

The material used in the covers were also selected for its resilience. Properly sized,
the covers provide a snug, secure fit. This helps keep connectors clean and prevents
the cover from accidentally falling off.
