Dome Washer – 12g, OD 25mm – Grey

The Aquaseal Dome Washer for 12g fasteners features a 25mm outside diameter and is made from high quality non-conductive thermoplastic elastomer (TPE).

Designed for fixing polycarbonate roof sheeting, the large dome-shaped washer helps support the sheet around the fixing. The large dome spreads the screw pressure over a wider area, helping to better protect the sheet when compared to smaller washers.

Polycarbonate can be damaged when fixing pressure is concentrated in one small spot. A dome washer is purpose-designed and provides better support.

Price listed per 1,000 washers. Box quantity = 5,000 washers.
