Please confirm the CCB-39600-1 quick drain hose’s compatibility with your aircraft using this document:
Curtis quick drains hoses are designed to work with the Curtis quick drain valves. In most cases, a simple push and twist action locks the quick drain hose in place. Waste liquid flows through five feet of high grade vinyl tubing, preventing messy spills and making a safer, cleaner environment. Tubing will not harden in sub-freezing temperatures.
