We will NOT fill any tanks manufactured of 6351-T6 aluminum alloy. Please see our 6351-T6 tank policy below.

Filling scuba tanks is hazardous and to ensure the safety of our staff and our customers we will not fill any scuba tank that does not have a visual inspection completed by Jolly Roger Diving within the last year. As a full-service dive center, we conduct numerous visual inspections and hydrostatic services for customers each year. Unfortunately, we encounter many tanks that have pre-mature corrosion inside of tanks due to poor compressor systems. These compressor systems are not in proper working condition and are introducing significant amounts of moisture to the tanks internally. Due to these issues we typically condemn a few tanks each year as they have exceeded manufacture specifications.

We provide free equipment evaluations for used scuba equipment. Bring the equipment to us and we will evaluate it for free and provide you with our professional opinion of the quality and approximate value of the equipment.
We evaluate everything from regulators, BCD's, along with all types of other scuba equipment including compressors.

To ensure the safety of individuals handling or around high-pressure tanks please adhere to the following procedures.
Fill your tanks at reputable dive centers with high quality air systems that properly remove all moisture and contaminants. I personally have been subject to bad air from poor scuba diving centers and have condemned many tanks due to poor air quality which results in excess corrosion within tanks.
Tanks should never have less than 20bar/300psi of pressure: This is to ensure that no water or hazardous substances will enter the tank.
Tanks should be completely rinsed with fresh water to remove all saltwater and salt residue. Proper care of your tank will ensure that they last for many years.
Tanks should always be stored upright: Tanks stored on their sides are more likely to have issues with corrosion that can lead to rupturing. There has been documented cases in which tanks with excess corrosion on the sides are more likely to rupture than tanks stored upright.
Do not attempt cleaning or removal of paint on the exterior of a tank by mechanical (power tools) or chemical processes. Using mechanical or chemical processes to remove paint from a tank can result in an inspector refusing to re-certify the tank as it may appear to have removed material from the tank making the tank wall thinner. Loose material may be manually scraped off but please do not use any power tools.
Tank valves should always be serviced every 5 years with the Hydrostatic re-certification. This is to ensure the valve remains in proper working order and do not leak while being stored.

For the safety of our staff and our customers Jolly Roger Diving WILL NOT FILL any scuba cylinders manufactured from 6351-T6 aluminum alloy.

Scuba cylinders have been manufactured from 6061-T6 and 6351-T6 aluminum alloys. The 6351-T6 alloy is subject to sustained load cracking (SLC) and can be extremely dangerous unless tested and certified using eddy current testing according to United States legislation and manufacturer's recommendations. Due to the issues with SLC the 6351-T6 alloy is no longer utilized within the USA in scuba tank manufacturing. Many of these older cylinders are still in service, are legal to use and are considered safe if they pass the periodic hydrostatic, visual and eddy current tests as required by regulation and as specified by the manufacturer.

Below is a list of cylinders with the specific information regarding their status within our policy.
