BtS Drysuit Inflation Set - 1L Steel

A complete BtS Drysuit Inflation Set including 1L Steel Cylinder, BtS Suit Inflation Mounting Straps and First Stage with built-in Over Pressure Relief Valve. All ready to go - just add a drysuit hose.

Dry Suit Inflation Cylinder

The steel 1L Drysuit Inflation Cylinder, available in white, is popularly used with air as an alternative suit inflation method and sometimes with argon for additional warmth. It is an ideal size for any twinset diver or CCR diver who doesn't need a larger capacity 1.5L inflation cylinder.

• Working pressure: 230 bar
• Weight without valve (empty): 1.72 kg
• Height (without valve): 28cm
• Diameter: 8cm
• BtS M18 valve: M18

BtS Suit Inflation Mounting Strap

A set of two BtS Suit Inflation Mounting Straps for drysuit inflation cylinders perfectly secures a suit inflation cylinder to your backplate. The steel book screws mount a drysuit inflation cylinder to the holes on the side of the backplate. The friction pad prevents the cylinder from sliding accidentally.

First Stage

The included piston first stage, featuring a built-in overpressure relief valve (OPV), is reliable and compact. 

• Built-in OPV set to 12-14 Bar
• Two LP ports - one used for the above OPV
• One high-pressure port

Recommended practice for suit inflation systems

• Never allow the suit inflation cylinder to fully empty underwater
• Storing cylinders with at least 2 bars of pressure in them
• Keeping/transporting any empty cylinder with the valve closed
• Drying and capping valves when the regulator is not attached
• Periodic check against moisture/water buildup in the cylinder

Do suit inflation cylinders need testing?

Cylinders that may, during normal use, lose all gas pressure above ambient when underwater, such as side-mount, bail-out, marker buoy, buoyancy compensator, and suit inflation cylinders, are at a greater risk of water ingress and internal corrosion when empty.

If fresh water is present inside a cylinder, it can cause the wall to lose more than 2mm of its thickness within six months. In salt water, this loss can exceed 5mm. (Diving cylinder walls are typically between 2 and 5mm thick).

While testing of the diving cylinder remains at 2.5 years for an internal visual and 5 years for a full hydrostatic test in the UK, a more frequent visual inspection by a certified test centre for suit inflation cylinders is recommended.

Deliveries outside the UK


Due to aviation regulations, the cylinder and valve will be shipped disassembled. It will be the customer’s responsibility to have the cylinder and valve reassembled.
