Product Information
The Seac Dry Suit Hose CM 75 is a genuine Seac replacement hose measuring 75 cm (about 30 in), made to replace the hose on a Seac Dry Plus 4.0 or Seac Warmdry dry suit. Seac's own spare parts catalog lists it generically as a "dry suit/BCD hose" under reference S850100 and part number 0390037000000A.
Who it is for
This hose is for divers who own a Seac Dry Plus 4.0 or Seac Warmdry dry suit and need to swap out a worn, cracked or leaking hose rather than replace the whole suit. It is a maintenance and repair part, not a complete dry suit accessory kit, so it suits owners doing their own service or a dive shop technician performing a hose replacement.
