Protective caps to shield unused RJ45 ports in demanding installations

These durable RJ45 cover caps provide a simple and effective solution for sealing unused data ports in harsh environments. Sold as a matching pair, each cap threads securely onto a Wakespeed-style RJ45 field housing to block moisture, dirt, and corrosion, helping ensure long-term reliability for alternator regulator systems, CAN data networks, and marine or vehicle signal lines. Whether used during installation, maintenance, or in permanent applications, the caps help safeguard exposed terminations from environmental contamination and mechanical damage.

Key Features

• Secure threaded closure: Designed to screw directly onto Wakespeed field-installed RJ45 housing ends, fully sealing unused connectors.
• Environmental protection: Helps shield ports against water ingress, dust intrusion, oxidation, and general contamination in rugged outdoor or engine-bay locations.
• Mechanical safeguarding: Protects delicate RJ45 interfaces from accidental knocks, abrasion, or strain while not in use.
• Ideal for marine, vehicle and industrial systems: Suitable for alternator regulator networks, CAN integrations, data monitoring links and onboard communications wiring.
• Sold as a matched pair: Two caps included to cover dual unused housings or provide a spare for future use.

These protective covers help maintain cable integrity and preserve long-term reliability where exposed RJ45 terminations are present.
