Blue Sea Systems 4136 White Push Button Circuit Breaker Boot, 3/8-27 Thread, Pack of 2

The Blue Sea Systems 4136 is a white waterproof boot made to protect thermal push button circuit breakers from spray, rain, and washdown water. It replaces the standard mounting nut on the panel-mount bushing of a thermal push button circuit breaker, sealing the button and threaded stem so the breaker can be used on exposed or waterproof panels without letting moisture reach the internal contacts. The boot is molded from a UV-resistant material that resists discoloration and cracking from sun exposure, making it suitable for open helms, flybridges, and other weather-exposed mounting locations. It threads onto a 3/8-27 stud using a nickel-plated brass thread insert for a corrosion-resistant, durable connection that will not seize or strip with repeated use. Each retail package includes two boots, so a single order covers two breaker mounting points. This boot is designed specifically for mounting on thermal push button circuit breakers and is not intended as a general-purpose nut replacement for other breaker or switch styles. It is a simple, low-cost way to extend the service life of push button breakers installed anywhere they may be exposed to water.
