Details

This 75mm Rubber Square Washer provides a specialized, heavy-duty seal for 90mm shower waste trap dip tubes. Unlike standard rounded O-rings, this washer features a square-edged profile to maximize the surface contact area between the dip tube and the trap body. This design creates a superior, airtight barrier that blocks foul drain odours and prevents water bypass. Manufactured from high-grade, chemical-resistant rubber, it maintains its shape and sealing properties over years of use. Consequently, it offers the perfect specific replacement for traps requiring a flat-seated seal.

A persistent drain smell in the bathroom often reveals a failing or compressed dip tube seal. Specifically, many modern 90mm shower traps rely on a square-profile washer to seat the internal bucket correctly; using a standard round O-ring in these units often leads to gaps and persistent leaks. When this specific seal perishes, sewer gases bypass the water trap and enter your living space. Furthermore, a loose-fitting dip tube allows hair and debris to enter the main pipework, causing frequent blockages. However, this 75mm Square Washer solves these issues. Its flat, square edges provide a much broader sealing surface than a traditional ring, ensuring a rock-solid, airtight fit. Therefore, you stop odours and protect your drainage system with a part designed specifically for the job.
