Start your adapter inquiry with the job you want the part to do. The K2 mask-to-cylinder adapter belongs to a breathing assembly for an identified K2 and compatible T-500 configuration. The Type 01 adapter is a filling accessory for an identified source cylinder and receiving cylinder. Name the job and both equipment ends so the supplier can respond about the correct part.
Compare the connection and the contents of the quote
| Product listing | What it is for | What to identify |
|---|---|---|
| K2 mask adapter | Connects a K2 mask with a compatible T-500 0.5 L breathing setup. | The exact mask, breathing assembly and T-500 configuration. |
| Type 01 refill adapter | A refill accessory for transferring suitable compressed air from compatible source equipment. | The receiving cylinder model and the source valve’s specification. |
The K2 adapter listing identifies the SKU TRIMIX-K2-ADAPTER. Its offered item is the adapter itself. The mask and cylinder have separate product and package entries. If an earlier quote was for a mask kit, ask the supplier to itemize the adapter and any other components already included.
The Type 01 refill adapter listing describes the refill application and lists supported receiving-model candidates. A qualified fill provider should assess the actual source valve, receiving equipment, pressure and air supply. Ask for written confirmation before ordering either accessory for an existing configuration.
Give the right people the information they need
Use the T-500 model manual to identify the documented equipment and precautions. Ask separately for instructions specific to the offered mask and adapter combination. If the mask is part of a compressed-air setup, take the complete configuration to a qualified instructor. DAN’s snorkeling and scuba guide explains why the change in breathing method introduces pressure-related considerations that require training.
For a parts inquiry, record the exact label on each item, whether it came in a kit and what the supplier has already confirmed. Ask which component number and instructions belong to your equipment. If you need the breathing adapter, use the K2 adapter inquiry and state the mask and T-500 configuration. If your question is about a fill connection, record the source-valve information and take it to a qualified fill provider.
