Bluecctv CN SB133 BNC coupler

This Bluecctv CN SB133 is a BNC male-to-male coupler designed for surveillance installations. It joins two female BNC cables to extend a video run without replacing the existing wiring. The adapter suits installers and system owners who need a quick, low-cost link between coaxial segments. It is not for users who require a gender changer to female or a different connector standard.

Tool-free coaxial installation

The coupler installs by hand with a simple push-and-twist onto each BNC jack, requiring no crimp tool or solder. A common issue is a loose connection if the knurled nuts are not fully seated, which can introduce signal loss or intermittent video. Ensure both centre pins are straight before mating to avoid bent contacts. The nickel-plated brass construction resists corrosion in indoor and sheltered outdoor runs.

Male-to-male BNC interface

The single specification that decides fit is the male-to-male BNC interface, compatible with RG-59 and RG-6 coaxial cables. This gender determines whether the coupler matches the female ports on your existing cables and equipment. Verify that both ends of your run present female BNC jacks before ordering.

Questions about this item

How can I verify the CN SB133 coupler is passing video correctly after connecting two cables?

Check the camera feed on your monitor or recorder; a stable, clear image without flicker confirms the BNC male-to-male connection is working as intended.

What comes with the Bluecctv CN SB133 and do I need extra parts to join two RG-59 or RG6 cables?

The package includes one BNC male-to-male coupler; both cables must already have female BNC ends, so no extra parts are required if your cables are terminated.

Which version of the Bluecctv coupler should I choose for RG-59 and RG6 coaxial cables?

The CN SB133 model is a single BNC male-to-male version designed to join two female BNC cables, compatible with both RG-59 and RG6 types.
