The Pepte Rubber Sealing Washers are essential maintenance components for DIYers and professional plumbers looking to repair or install M10 flexible tap tails. These NBR70 nitrile rubber washers provide a reliable, leak-proof seal at the tap connection point, ensuring long-term durability against water and heat. While these washers are highly effective for standard M10 fittings, users should ensure they are not overtightened during installation, as excessive force can compromise the integrity of the rubber seal.

Yes, they are rated for temperatures up to 120C, making them ideal for both hot and cold water supplies.
No, these are specifically designed for 10mm M10 flexible tap tails.
This product comes in a pack of 10 washers.
NBR70 refers to Nitrile Butadiene Rubber with a hardness of 70 Shore A, which balances flexibility and durability.
Generally, no. The rubber washer acts as the primary seal; adding tape to the thread is unnecessary and may interfere with the washer seating correctly.
Check if the washer is seated squarely or if the tap tail surface has scratches that prevent a full seal.
Ensure the washer is the correct size and not 'bunched up' inside the connection point.
To install, ensure the tap tail thread and the internal seat of the tap are clean and free of debris. Slide the 10mm washer onto the M10 tail end and ensure it sits flush against the fitting surface before tightening. Compatibility is limited strictly to M10 flexible tap tails; verify your connection size before purchase. For care, do not use chemical sealants or petroleum-based lubricants on these washers as they can degrade the rubber. Hand-tighten the tap tail until firm, and use a wrench for a final quarter-turn to compress the washer properly without damaging the threads.
