3 Foot Extension Tube for Vacuum Relief Nozzle

This is an all-aluminum extension that can be attached to the end of the Vacuum Safety Shutter Nozzle. This allows you to insert the Vacuum nozzle underwater or in areas where you need extra distance. They connect to the Safety nozzle by way of the 4” or 6” clamps. See part numbers 690-077 and 690-078.
