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.
Choose your refill method.
Match the cylinder first, then check the adapter’s source-valve connection. The pairings below follow the current TRIMIX kits.
Scroll sideways to compare all three models.
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.

Type 01 compact adapter
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.

Type 02 hose-and-gauge adapter
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.

Existing product photographs are shown unchanged. Brand markings remain as photographed; the images do not establish a universal connection standard or a pressure rating.
Check both ends of the connection.
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.
Ask TRIMIX to check your refill setup
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.
