Match the part to your equipment
Modular BCD components and regulator accessories can be specific to a range or generation. Check the model name, size and part number before choosing a replacement. Keep any original documentation handy so our team can help narrow down the right component.
Explore the wider Parts and Accessories collection to compare related equipment and accessories.
Check modular parts and kit contents
For an Omni or Rogue component, confirm the BCD range, selected size and how the part connects to your existing equipment. A modular component is not automatically a complete BCD; check the product listing for the assembly or accessories supplied.
Check quantities on replacement accessories too. Phazer bungee straps are listed as a pair, while computer protectors are selected by the exact supported model. Read the individual listing before adding a part to your kit.
User replacements and service work
Follow the equipment maker’s instructions when fitting a replacement strap, protector or modular accessory. Confirm that the replacement is intended for the model and that you can complete the required fitting checks.
Internal regulator work, pressure-system repairs and parts that require professional installation should be assessed by a qualified service technician. Ask our team to help identify the correct item and service arrangement before ordering if the requirement is unclear.
