22-20 GA PURPLE SEAL WP/MP

22–20 AWG Purple Wire Seal — Weather-Pack and Metri-Pack Connector Sealing

The 22-20 GA Purple Seal WP/MP (SKU 15324985) is the colour-coded cylindrical wire seal for 22 to 20 AWG conductors used in Weather-Pack and Metri-Pack sealed connector assemblies. This small but critical component is the element that creates the environmental seal around the individual wire entry point in each connector cavity — without it, or with an incorrectly sized seal, the connector loses its IP-rated protection against moisture, dust, and fluid ingress.

Wire Seal Colour Coding in Sealed Connector Systems

Weather-Pack and Metri-Pack sealed connector systems use colour-coded wire seals to allow the assembler to quickly identify the correct seal size for the wire gauge being used. The purple colour designates 22–20 AWG — the most common fine signal wire gauge range used in engine management, sensor circuits, and ECU harnesses throughout motorsport and automotive wiring. Using the wrong size seal — even one that fits over the wire — results in a poor environmental seal that allows moisture ingress and eventual connector corrosion.

Key Features

• Purple colour coding — designates 22–20 AWG wire gauge range
• Compatible with Weather-Pack (WP) and Metri-Pack (MP) sealed connector systems
• Creates the environmental seal at the wire entry point in each connector cavity
• Must be installed over the wire before terminal crimping
• Correct seal is essential for IP-rated connector performance
