Filter issue

I have 300L tropical tank and I’ve been using a Aqua One Nautilus 1100 since I got the tank around 4 years ago. The only issue I’ve found is the end cap for the spray bar is constantly dislodging from the tube to the point where I am having to physically block the end cap from coming out. I have replaced the spray bar and cap multiple times and am getting tired of having to buy replacements. I know I could probably just glue the cap in but I was wondering if it would just be better to get a deferent filter??
