Review on 🔵 Spectre Performance 9776 Blue 4-inch Intake Coupler: Enhanced Airflow and Durability by Matthew Sutton

Just what I needed to add a waste water connector and metering valve assembly to my existing line. I had to cut out the old assembly at the linkage hub, leaving a 4″ diameter tube that I had to connect to the new assembly's linkage hub (the standard 4″ rubber linkage was too big as it's almost 1/2″ too big ). than 4"), but it fits perfectly, is tight and still hasn't leaked after weeks of watching.
