How can I make a waterproof telephone wiring connection?
There are several types of waterproof connectors used in phone wiring. The three most common types are: EX Connectors or “Jelly Filled Beanies” Use these where you have exposed leads or corroded wires. Beanies cut through and displace the insulation on up to 3 conductors. Beanies take longer to crimp than the Scotchflex connectors below, but they have a larger contact surface area. These are filled with a waterproof gel and work well on a wide range of conductor sizes, from 18 to 30AWG. UR and UY Connectors Made by Scotchflex, these connectors are quick to install. The UR is a butt-splice type connector, and the UY is an inline connector. Use pliers for a good crimp, and make sure the red button ends up level with the body of the connector. If it is tilted, it won’t make a good connection. Scotchflex connectors work on wire sizes from 19 to 28 AWG. There are also larger connectors, such as BPTS splices which are can handle up to 200 conductors.
