The hose to tank connector leaks. The seal is an exposed o ring. It's only air tight when the o ring is squeezed at the perfect point. If the hose screwed in too tight, the o ring deforms and leak. If wiggled the hose, it will leak. I plan to use this as alt during scuba diving, and mount at my back. So it can totally leak all the air during a dive. ## Features - 【HOUVAN S400】The HOUVAN S400 scuba tank breathing valve adopts the latest constant pressure design, which can also be adjusted by opening and closing the control valve, which is safer than the previous direct suction breathing valve. The diving tank is made of 6061 aviation aluminum, which is extremely strong. At the same time, when the body of the diving cylinder is separated from the valve head, it can be safely carried on the plane and follow you to where you want to go. - 【Approximately 75 breaths 】HOUVAN S400 mini scuba tank is CE/DOT certified, with a capacity of 1.0L, which provides approximately 75 breaths at 200 bar pressure (tested at a depth of 16 feet).The specific use time is determined by factors such as breathing rate and diving depth. Note: Do not dive in waters over 16 feet and below 50 degrees Fahrenheit. - 【Multiple Filling Methods】The scuba tank has an 8mm inflatable interface and can be inflated in most professional dive shops. Use a scuba adapter to introduce compressed air from the big cylinder into the scuba tank, which can be filled in just 10 seconds. It takes about 26 minutes to use an HOUVAN air compressor.The manual pump takes about 50 minutes to inflate, which is quite laborious and is recommended as a backup.The working pressure is not more than 3000PSI/200bar/20Mpa. - 【Applicable multiple scenarios】 The HOUVAN S400 scuba tank can be used as both a beginner diving practice and a backup source for professional divers. The same applies to dangerous underwater rescue and fire rescue operations. This mini scuba tank is easy to carry and easy to operate, and can be used for a variety of scenarios such as boat bottom cleaning, pool search, underwater photography, underwater exploration, etc., which is a must-have perfect equipment for outdoor diving. - 【Our Service】You can get: S400 diving cylinder, 1.0L cloth bag, scuba adapter, mini hand pump, user manual and some other extra accessories.
