3/4'' Flexi Hose Washer Rubber

3/4'' Flexi Hose Washer Rubber

he 3/4" Rubber Flexi Hose Washer is a fundamental sealing component designed to create a watertight, leak-proof connection in high-flow plumbing installations. Specifically engineered for use with 3/4" BSP (British Standard Pipe) female threaded fittings, this washer sits securely inside the nut of a flexible hose or appliance connector, compressing against the male thread to prevent water escape under pressure.

Key Features and Sealing Integrity
Compliance: Manufactured to high industry standards, ensuring the material is safe and durable for use in domestic hot and cold water systems.

Material: Produced from high-quality Black Rubber (EPDM), chosen for its excellent elasticity, resistance to "setting" under pressure, and durability against the thermal cycles of hot water systems.

Dimensions: Precision-cut for 3/4" (20mm) threaded connections.

Outer Diameter: Sized to fit snugly inside a standard 3/4" BSP nut.

Thickness: Optimized to provide maximum compression without distorting or obstructing the flow of water.

Function: Acts as a mechanical seal that fills the microscopic gaps between the two flat faces of a threaded connection. It eliminates the need for jointing compounds or PTFE tape on the threads of flexible hoses.

System Suitability: Ideal for washing machine hoses, dishwasher inlets, and large-bore flexible tap connectors (standard for many kitchen mixers and bath taps).

The Installer's Advantage
A fresh rubber washer is the simplest way to prevent "nuisance leaks" in appliance and tap installations. Over time, original washers can become brittle, compressed, or perished, leading to slow drips. Professional installers recommend replacing the washer whenever a flexible hose is disconnected and re-installed to ensure a reliable, "first-time" seal. These washers provide a resilient interface that can absorb minor vibrations and pipe movements without failing.
