KarlKers Solar Connector Caps IP67 Dustproof MC-4 End Caps (5 Pairs)

Overview

When solar connectors are idle, they come under exposure to the elements. KarlKers Solar Connector Caps provide practical protection for MC-4 connectors, guarding against debris, moisture, and oxidation. This set includes five pairs, giving you flexible coverage across multiple lines or components in a single install.

Weatherproof and Dust-Resistant Design

With an IP67 rating, these caps seal securely to keep dust and water out while stored or disconnected. They help keep the connectors clean and dry, supporting a longer service life for your MC-4 assembly.

• IP67 waterproof and dustproof performance for reliable idle protection
• Protects enclosure interfaces from dust, moisture, rust, and oxidation
• Helps preserve connector integrity between maintenance cycles

Material Durability and Temperature Readiness

Crafted from environmentally friendly silicone, the caps stay soft, flexible, and elastic. They resist cracking under temperature swings, with a wide range from -40°F to 212°F (-40°C to 100°C). This resilience helps the caps perform in diverse outdoor environments without stressing the connectors.

• Soft, flexible silicone that cushions the connector interface
• Flame retardant and high-temperature resistant characteristics
• Operating range: -40°F to 212°F (-40°C to 100°C)

Compatibility and Easy Use

The caps are precision-molded for broad MC-4 compatibility, offering a seamless fit that’s easy to install or remove without tools. The design ensures a snug seal across various MC-4 configurations, reducing the likelihood of accidental exposure when not connected.

Versatile Applications
