The Sea Elite Octoflate comes with the inflator hose, the BCD air tube (not shown), and plastic coated pull cable for the dump valve. I integrated this high quality unit onto my MARES Pegasus BCD. However, it was not a direct fit. I had to use the MARES BCD air tube and pull 'rope'. The tube barely fit onto the Octoflate port. Also the inflator hose has a custom quick disconnect, so it is not compatible with BCD's not equipped with the Octoflate. The Sea Elite Octoflate is amazingly good for the price. It has a fine degree of control over inflation and exhaust. It also breathes better than most separate Octopuses! Although this unit is not as attractive as some others it is a great performer. I highly recommend it!
