Images above show the cylinder and breathing assembly only. They are not a complete packing list.
* Breathing times are TRIMIX reference maximums, not guaranteed usable dive times. Actual duration varies with depth, breathing rate, activity and starting pressure. The supplied manuals do not promise a fixed runtime; plan an adequate air reserve.
T-500: compare the four 0.5L packages below to choose a cylinder-only, pump or mask configuration.
T-1000: compare its 1L hose-connected layout with your equipment and refill plan.
T-2000: the 2L listing includes a tank vest and carry bag, with an optional refill adapter.
Every package below uses the same 0.5L T-500 cylinder. The mask, filling equipment and carrying bag are what change.

Some photos show an optional adapter. It is supplied only with a selected With scuba adapter configuration. Both adapter choices in T-500SM4P include the four-stage pump.
An action camera, electric compressor and large refill source cylinder are not included in these packages. Check the product page and selected configuration for final packing details.
Match the cylinder first, then check the adapter’s source-valve connection. The pairings below follow the current TRIMIX kits.

The cylinder limit is 200 bar / 20 MPa, subject to the actual markings. This does not establish the pressure rating of a source cylinder, adapter, hose or other filling component.
The table identifies current kit pairings. It does not establish that an alternative adapter is interchangeable or unsuitable. Have the complete connection checked before choosing a substitute.
Professional filling is another route to investigate: ask a dive center whether it accepts your cylinder, markings, inspection status and fittings. Acceptance is not guaranteed.
Current model pairing: T-500, T-500-4P, T-500SM and T-500SM4P.
Compact body with a direct quick coupling; no transfer hose or separate gauge is shown.
Merchant reference for this compact adapter: 200 bar / 20 MPa working pressure. Follow the actual component markings.

Current model pairing: T-1000 and T-2000.
Larger body with a transfer hose, quick coupling and pressure gauge.
Confirm the adapter and hose working-pressure markings. The gauge scale is not a working-pressure rating.
View adapter and enquireExisting product photographs are shown unchanged. Brand markings remain as photographed; the images do not establish a universal connection standard or a pressure rating.
At the source cylinder: the adapters are pictured with a clamp-style connection. The exact valve standard, sealing face and working-pressure compatibility need confirmation. Send the valve’s specification or a clear photo; do not choose by cylinder capacity alone.
At the receiving cylinder: the manuals identify an 8mm male fill plug. Match the actual coupling profile, clearance and seals. “8mm” alone does not prove compatibility.
For air quality: use breathing-quality compressed air. A pump’s pressure rating or an oil-water separator alone does not establish breathing-air quality. See DAN’s guidance on breathing-gas quality.
The K2 mask-to-cylinder connector is part of the breathing setup. It is a different item from either scuba refill adapter. Follow the cylinder and filling-equipment instructions; a qualified provider should control the transfer and depressurize the connection before disconnection.
The 0.5L refill-time illustrations in the T-500 pages are conditional merchant references for that cylinder only. They are not fill-time estimates for T-1000 or T-2000.
T-500SM uses the foldable mesh carry bag. T-500SM4P adds the four-stage pump and uses a long zip carry case. The cylinder-and-pump T-500-4P has a black cylinder shoulder bag.
The K2 mask-to-cylinder connector is part of the mask kits. The optional Type 01 compact scuba refill adapter transfers air from a compatible source cylinder. T-1000 and T-2000 are paired with the larger Type 02 hose-and-gauge adapter. Confirm both connections with TRIMIX; see the refill table above.
A mask, pump or bag does not increase the T-500 cylinder’s 0.5L capacity. Choose accessories around your intended setup and refill plan, rather than assuming a larger package provides more breathing time.
The hand-pump packages provide a manual filling option that requires sustained effort. For every method, confirm equipment compatibility and breathing-air quality. Read the model-specific manuals and refill guidance.
