Product Information
The SeaLife YS Adapter for Flex-Connect (SL994) is a small mounting adapter that lets any underwater light or flash with a standard YS mount lock onto SeaLife's Flex-Connect grips, trays, arms, and cold shoe mount accessories. It measures 1.5 in wide by 2.9 in tall, weighs 1.3 oz, and is molded from black polycarbonate with a grey rubber O-ring for a secure, negatively buoyant connection underwater.
Who it is for
This adapter is for divers and underwater photographers who already own a YS-mount light or strobe and want to integrate it into a SeaLife Flex-Connect camera setup. It solves the common mismatch between YS-style lighting and Flex-Connect trays, arms, and grips, so there is no need to worry about compatibility issues when expanding a Sea Dragon lighting system from a compact configuration to a full tray-and-arm rig.
Key details
- Locks into Flex-Connect accessories with a flush red release button that prevents accidental disconnection.
- Rotates a full 360 degrees left to right on its base for flexible light positioning.
- Up and down pivot is controlled by the butterfly screw on the attached light or device, not by the adapter itself.
- Built from black polycarbonate with a grey rubber O-ring, weighing 1.3 oz / 36 g, and negatively buoyant.
Compatibility and sizing
The adapter works with any underwater light or flash that uses a YS mount, and connects that light to SeaLife Flex-Connect grips, trays, arms, and cold shoe mounts. The butterfly screw used to set the up and down angle is supplied with the light or device itself and is not included with this adapter.
What's in the box
- One Flex-Connect YS Adapter (butterfly screw for the light or device not included)

Frequently Asked Questions
Does the SeaLife YS Adapter include the butterfly screw for mounting a light?
No. The adapter itself does not include a butterfly screw. The butterfly screw that controls the up and down pivot angle is supplied with the underwater light or flash you are attaching, not with the SL994 adapter.
Will the YS Adapter work with any YS-mount light, or only SeaLife lights?
The YS Adapter is designed to work with any underwater light or flash that uses a standard YS mount, not just SeaLife lighting. It connects that YS-mount device to SeaLife Flex-Connect grips, trays, arms, and cold shoe mount accessories.
What materials is the SeaLife YS Adapter made of?
The adapter is made from black polycarbonate (PC) with a grey rubber O-ring. It weighs 1.3 oz / 36 g and is negatively buoyant, so it will sink if detached underwater rather than float away.
Can the YS Adapter rotate and tilt once a light is attached?
Yes. The adapter rotates a full 360 degrees left to right on its base. Up and down tilt is controlled separately by loosening or tightening the butterfly screw on the attached light or device, since the adapter itself does not include a tilt mechanism.
