Product Information

The SeaLife O-Ring Set for SportDiver and SportDiver S Housing (SL40010) is a replacement sealing kit that restores waterproof integrity to SeaLife's SportDiver underwater smartphone housings. It includes a main seal o-ring and a vacuum check port o-ring, and it is built specifically for the SL400, SL400-U, and SL408 housings.

Who it is for

This o-ring set is for SportDiver owners performing routine maintenance or replacing worn, nicked, or aged seals before a dive trip. Anyone who notices a scratched or compressed o-ring on their housing, or who services the housing on a regular schedule to prevent flooding, needs this kit on hand. It is not a fit for owners of the SportDiver Ultra Housing (SL405), which uses a different, separately sold o-ring kit (SL40510).

Frequently Asked Questions

Does this o-ring set fit the SportDiver Ultra Housing?

No. The SL40010 o-ring set fits the SportDiver (SL400, SL400-U) and SportDiver S (SL408) housings only. The SportDiver Ultra Housing (SL405) uses a different o-ring kit, SL40510, which must be purchased separately.

Do I need o-ring lube with this kit?

Yes. The SL40010 set includes the o-rings only; lubricant is sold separately. SeaLife recommends its Silicone O-ring Lube (SL9807) to properly install and maintain the main seal o-ring and vacuum check port o-ring.

How should the main seal o-ring be installed?

The main seal o-ring must be installed with its flat side facing inward. Correct orientation is important for a proper watertight seal.

What exactly comes in the SeaLife O-Ring Set SL40010?

The kit includes two o-rings: one main seal o-ring and one vacuum check port o-ring. Both are sized and designed specifically for the SeaLife SportDiver and SportDiver S underwater smartphone housings.
