Product Information
The Tusa Snorkel Adaptor Assembly (TC-506) is a replacement oval, two-piece snorkel adaptor finished in white, built to fit the Tusa SP-110, SP-130, SP-170 and SP-200 snorkels. It is also catalogued under the alternate part code SPU-117-WH and carries the manufacturer part number TC-506.
Who it is for
This adaptor is for divers and snorkelers who already own a Tusa SP-110, SP-130, SP-170 or SP-200 snorkel and need to replace a lost, cracked or worn snorkel adaptor on one of those models. It is a spare part rather than a complete snorkel, so it suits someone doing a repair or swap rather than a first-time snorkel purchase.
