Premium‑quality TRITON Shower Burst Disc Seal – Black (Pack of 6) is the perfect replacement for the pressure‑relief device (PRD) in any Triton electric shower. Made from durable rubber, each disc is designed to burst safely if water can’t escape through the shower head, protecting the heating tank from over‑pressure damage.
What’s in the box
– 6 black burst‑disc seals, ready to install
Fitment
These seals are compatible with the majority of Triton models – from classic Amber and Aquasurge to newer T‑series and Topaz ranges. If your shower uses the “new style” black PRD (part numbers 82800450 or 83301330), this kit will fit perfectly.
Easy installation
1. Turn off the water and disconnect the hose.
2. Unscrew the outlet pipe to expose the PRD.
3. Remove the two mounting screws, take out the old disc and press the new one firmly onto the PRD.
4. Re‑mount the PRD, tighten the screws, reconnect the hose and cover.
5. Run a cold‑water cycle first to let the tank refill before using hot water.

– Cost‑effective: Six discs per pack give you long‑term peace of mind.
