O-Ring Replacement for DC2000 and DC1400

Quick answer

Replace the O-ring on your SeaLife DC2000 or DC1400 housing every 12 months or whenever you notice damage. The process is the same for both models and takes about 10 minutes.

Step-by-step replacement guide

1. Remove the old O-ring: Open the housing and carefully lift the O-ring out of its groove using a plastic O-ring removal tool or your finger. Do not use metal tools — they can scratch the groove surface and cause future leaks. Common mistake: using a sharp tool that gouges the groove.
2. Clean the groove and O-ring: Wipe the groove with a lint-free cloth slightly dampened with fresh water. If the old O-ring is still in good shape (but you plan to replace it anyway), clean it as a spare. For the new ring, skip cleaning — it is already factory-clean. Common mistake: leaving old grease or grit in the groove, which prevents the new ring from seating.
3. Lubricate the new O-ring: Apply a tiny amount of silicone grease to your fingers and run the O-ring through your fingers to coat it evenly. Do not apply grease directly into the groove — excess grease attracts debris. Common mistake: using too much grease, which can trap sand and cause a leak path.
4. Install the O-ring: Place the lubricated O-ring into the groove, working it around with your fingertips. Ensure it lies flat without twisting or bunching. The ring should sit evenly all the way around. Common mistake: installing the ring twisted — rotate it to check for even tension.
5. Close and test the seal: Close the housing back and latch it securely. Submerge the closed housing in a bucket of fresh water (without the camera inside) and press all buttons to check for bubbles. If you see bubbles, open, reseat the O-ring, and test again. Common mistake: skipping the pressure test and discovering a leak underwater.
