Universal 1/2" Fibre Washer Pack Of 10 (Boilers Gas Fires Diverter Valves)
The Universal 1/2" Fibre Washer Pack of 10 is a trade-grade selection of heavy-duty sealing gaskets engineered specifically to create permanent, leak-proof compression seals across domestic gas boilers, gas fires, and plumbing manifolds. Fabricated from premium vulcanized fiber material, these washers are designed to bridge the mechanical tolerances between flat-faced brass fittings, copper tails, and diverter valve connections. Upon tightening the union nut, the fiber matrix undergoes controlled micro-expansion when exposed to moisture, packing out tiny surface imperfections to prevent weeping under high operating pressures.
Controlled Swell Sealing: The specialized vulcanized fibers expand subtly upon contact with fluid, ensuring a tightly bound, hermetic seal that actively counteracts micro-vibrations and thermal expansion.
High Thermal Stability: Engineered to withstand the relentless high-temperature cycles and fluctuating hot water demands characteristic of modern combination boiler networks and gas appliances.
Aggressive Fluid Resistance: Chemically stable design that resists breakdown when exposed to commercial central heating inhibitors, system flushing chemicals, and corrosive magnetite sludge.
Standard 1/2" Universal Fit: Precision-stamped to universally match standard 1/2" BSP plumbing connections, making it an essential service-kit standard for fast, dependable maintenance overhauls. Compatible Models:
