Item/Items are being sold For Parts or Not Working. Only the items shown in the photos are included. Unfortunately we don't have any information to go on as far as capabilities for these cylinders and cannot identify brand or a part number. Also we are unable to bench test the item(s), so they are being sold as-is, untested, and for parts.

The 3 silver cylinders appear to be the same size and shape, while the white one is a little over an inch shorter for the tube length.

All items sold at Max Marine Outlet come as you see in the pictures provided, with only the parts and accessories stated in the description section named “What’s Included”. IF YOU DO NOT SEE SOMETHING YOU EXPECT TO BE INCLUDED IN THE DESCRIPTION WE PROVIDE, IT WILL NOT BE INCLUDED. Read all descriptions thoroughly. There are times when a display is used only to show the item being sold is functional and working properly. In this case, these displays are not included. If you have any questions feel free to reach out. We always want to be transparent with our customers and fully disclose any information regarding the products we sell.
