100-Piece Blue B Wire Cap Connectors

This pack supplies 100 blue B-style wire cap connectors filled with corrosion-resistant silicone gel. They are designed for low-voltage splicing tasks in telecommunications, alarm and CCTV installations. Each connector accepts up to four unstripped solid or stranded 22 AWG conductors and handles wire gauges from 18 to 30 AWG. The UL-listed components provide a moisture barrier that does not harden over time.

Installers needing gel-filled splices for 18-30

Technicians who require a waterproof, insulation-piercing crimp for telephone, alarm or CCTV circuits will find these connectors match the standard B-connector profile used in those industries. The soft brass crimp and gel fill create a dependable, corrosion-resistant joint without stripping the wires. Buyers who need dry connectors, a different colour code or splices for conductors larger than 18 AWG should look at alternative products.

18 to 30 AWG wire gauge range

The single specification that determines fit is the supported wire gauge span of 18 to 30 AWG. Only conductors within this range will seat correctly in the insulation-piercing teeth and achieve a solid, gel-sealed splice. Using wire outside this span will prevent proper crimping and compromise the moisture barrier.

Questions about this item

Do the silicone-filled caps need any re-gel or replacement after installation?

The non-hardening gel stays flexible and corrosion-resistant for the life of the splice, so no re-gel or periodic replacement is required.

How many 22 AWG strands can one connector accept before it reaches its mechanical limit?

Each connector is designed to accept up to four solid or stranded 22 AWG wires unstripped, which is the maximum fill for a reliable crimp.

Does the brass crimp or gel soften when the connectors run warm all day in a telecom cabinet?

The soft brass crimp and silicone gel are rated for continuous low-voltage use and do not soften or degrade under normal cabinet temperatures.
