Ideal Standard Sealing O-Ring — A961338NU
The Ideal Standard A961338NU is an authentic replacement sealing O-ring engineered to restore a watertight connection across a broad selection of premium domestic and commercial tap mixers. Over time, original rubber seals can flatten, perish, or suffer abrasion from chemical cleaners and hard water friction, resulting in persistent weeping or base leaks. Swapping out the worn seal with this factory-original component safely preserves system pressure and keeps your tap assembly dry and operational.
