A 40 mm rubber seal designed specifically for Triton Aquatronic T100, T70 and T80 shower valves (also compatible with many Wickes electric showers). This premium‑grade replacement part restores a tight seal on the stabiliser valve, eliminating drips and restoring consistent water pressure.
Key specifications
– Diameter: 40 mm (4 cm)
– Thickness: 4 mm
– Fits stabiliser valve numbers 82600250, 82600700, 82600780, 82600810, P1212080 – the same dimensions as the original OEM part (82600250).
Why you need it
A worn seal is the most common cause of a leaky shower. Swapping the old rubber for this new one stops water from escaping the valve and helps the heater maintain its set temperature.
Easy DIY installation
1. Remove the front panel of the shower to expose the stabiliser valve.
2. Unscrew the four top screws (or release the metal clip on older models).
3. Pull out the old seal and press the new 40 mm seal into place.
4. Re‑assemble the panel and tighten the screws.
Compatible models (2002‑present)
Aquatronic series (1‑4, Ultra), T100/T70/T80 families (including XR, i, Si, Eco), T300 series, Topaz, Trance 2, TX8500I, W8500 and all Wickes Aquatronic variants.
Replace this seal whenever you notice a steady drip or reduced flow – it’s a quick fix that saves you from costly professional repairs.
Note: This is a high‑quality aftermarket part; it is not an original manufacturer component but matches all required dimensions and performance standards.
