## Summary description

VALUE 21.99.3000 is an RJ-45 cable combiner/connector with female-to-female ports in black and blue. It provides simple inline coupling for Ethernet cables, preserving connector gender and allowing quick extension or reconfiguration of network patching. Suitable for Cat.6/Class E cabling environments and industrial/outdoor use where compatible.

## Long description

VALUE 21.99.3000 is a Cat.6a RJ‑45 female‑to‑female cable combiner designed for inline coupling or extending Ethernet patch cables in industrial and outdoor environments. The coupler provides two shielded RJ45 ports and a dustproof cable gland that protects the connection from moisture and soiling. It supports cable diameters from 3 to 8 mm and is compatible with patchcords having an outer diameter of 6–8 mm for best waterproofing. The unit has eight contacts wired 1:1 and a length of 121.5 mm with an overall diameter of 28 mm.
Advantages
The combiner enables quick and easy extension or reconfiguration of network patching without changing connector gender, preserving shielded connections for Cat.6/Class E cabling. Its dustproof gland and sealed design offer added protection against dirt and moisture, making it suitable for industrial or outdoor installations where a robust inline connection is required. Installation is straightforward and does not require special tools.
Suitable for
Extending or joining Cat.6a/Cat.6/Class E Ethernet patch cables
Industrial or outdoor network connections requiring dust and moisture protection
Temporary or permanent inline coupling where female‑to‑female connection is needed
When it may not be suitable
The combiner is intended for inline coupling of patchcords and does not replace a permanently installed connectorized cable or a fully sealed IP‑rated enclosure. It does not include integrated surge protection or data conversion features. For cables with outer diameters outside the 3–8 mm range or where stricter IP ratings are required, consider purpose‑built connectors or housings.
Key specifications
Connector type: 2 × shielded RJ45 female ports
Category compatibility: Cat.6a / Cat.6 (Class E)
Contacts: 8 contacts, 1:1 wiring
Cable diameter support: 3–8 mm (recommended patchcord O.D. 6–8 mm for waterproofing)
Dimensions: length 121.5 mm; diameter 28 mm
Colors: Black / Blue
How to use
Prepare two compatible shielded RJ45 patch cables with outer diameters within the supported range. Insert each cable's RJ45 plug into the corresponding female port of the combiner until it clicks. Tighten the dustproof cable gland as needed to secure the cable and improve resistance to moisture and dirt. Verify the connection by testing network continuity and performance; the combiner maintains 1:1 wiring across all eight contacts.
What to consider before purchase
Verify cable outer diameter (recommended 6–8 mm for best waterproofing)
Ensure Cat.6a / Cat.6 compatibility for required data rates
Confirm that a female‑to‑female coupler fits your planned cabling layout
Assess whether additional environmental protection or surge protection is needed
Usage recommendations
Use shielded Cat.6a patchcords with appropriate outer diameter, tighten the cable gland to maintain dust and moisture resistance, and test the link after installation to confirm performance.
