Engineered for Reliable Sealing in Plumbing, Valve, and Industrial Applications

This 10-piece silicone flat washer set is designed for professionals and DIY users who require high-performance sealing in pipe fittings, faucet systems, hose bolts, and valves. Made from durable, flexible silicone rubber, each washer offers exceptional sealing performance, temperature resistance, and chemical stability.

Whether you're maintaining a home plumbing system, building laboratory equipment, or working on industrial sealing projects, these washers are made to deliver long-term value and durability.


Key Features That Make This Washer Set the Best Choice

✔️ High-Grade Silicone for Long-Lasting Performance

Manufactured with premium silicone rubber, these washers remain elastic, anti-aging, and stable across a wide temperature range of -60°C to 250°C (-76°F to 482°F).

✔️ Multiple Sizes for Flexible Use

Each pack includes inner diameters from 2mm to 12mm (0.08” to 0.47”), and thicknesses of 1mm, 1.5mm, 2mm, and 3mm (0.039” to 0.118”), suitable for both tight tolerance industrial applications and flexible home use.

✔️ Leak-Proof and Energy-Saving

Provides a tight seal for faucet pipes, valve bodies, hose connectors, and more—stopping leaks and conserving water or fluid pressure effectively.

✔️ Resistant to Corrosion and Wear

Ideal for corrosive environments and high-frequency usage. The washers resist oil, chemicals, UV rays, and general wear-and-tear—perfect for long-term, worry-free use.
