Deutsch ASU Gasket Shell Size 3 — Environmental Sealing Gasket for Autosport Circular Connectors
The Deutsch ASU Gasket Shell Size 3 — SKU: GV-3 is a precision moulded environmental sealing gasket for Deutsch Autosport ASU series circular connectors at shell size 3. The gasket seals between the mating connector shell faces when the connector is fully engaged, providing IP-rated protection against moisture, dust, fuel, oil, and contamination ingress through the connector interface in professional motorsport wiring harnesses across Norway, Sweden, and Denmark.
What Does the Autosport Connector Gasket Do?
Deutsch Autosport circular connectors achieve their environmental sealing rating through a combination of individual contact seals, rear insert sealing, and the front-face shell gasket. The shell gasket compresses between the plug and receptacle shell faces when the connector is locked — creating a positive moisture barrier around the entire connector interface perimeter. Without a correctly fitted gasket, moisture can track between the mated shell faces and reach the contact area, causing corrosion and contact resistance increases that degrade electrical performance in the damp and wet conditions common at Scandinavian motorsport events.
Shell Size 3 — Connector Family Context
This gasket is sized for a small shell size used with ASU series compact Autosport connectors. It is a wear item that should be inspected and replaced if damaged, compressed, or deformed during connector servicing — a damaged gasket compromises the connector’s IP sealing rating regardless of the condition of the connector shells and contacts.
