Olympus recommends maintenance of your UW housing's O-ring before each dive. Apply a thin coat of the Olympus silicone grease to ensure a waterproof seal. For more detailed directions review your underwater housing instruction manaul. For a larger size container, use Item #202180 Silicone Grease Tub for PT Series Underwater Housings.
Amazingly compact and so light you’ll barely notice it, the new UFL-3 underwater flash is a serious tool for serious divers. Waterproof to an incredible 246 feet (75 meters), this adaptable flash is specifically designed to work seamlessly with a number of Olympus camera/underwater housing combinations.
The PTSA-03 is an accessory short arm used to mount underwater strobes such as the UFL-1 or UFL-2 to the accessory shoe of the PT series underwater housings. It can also be used for attaching a focusing light to the housing when using the underwater strobe on an external bracket. It is made of a corrosion resistant plastic resin and features a large easy to turn knob, making for easy swivel adjustment even when wearing dive gloves. Attaches to any Olympus PT series housing that has an accessory shoe.
