A four-pack of flat silicone washers with a 6 mm inner hole, 40 mm outer diameter and 2 mm thickness. The soft, resilient silicone compresses into uneven joint faces to seal faucets, shower heads, filters, solenoid valves and pump fittings, and it also damps vibration and insulates electrically. The wide 40 mm face spreads load over a larger area than a standard narrow O-ring, which suits flat sealing grooves and flange faces rather than thin compression fittings. It is a general-purpose plumbing and equipment part, not a precision OEM replacement, so check the groove and bolt size before relying on it.

This set includes 4 black silicone flat washers. Each has an M6 mm inner diameter, a 40 mm outer diameter and a thickness of 2 mm. The silicone is moderately soft and resilient, so the washer presses tightly against uneven joint surfaces and fills tiny gaps under pressure.
The silicone resists weak acids, weak alkali, oil and aging. It also absorbs shock and cushions parts, which reduces vibration and noise from equipment operation and water impact. It keeps metal parts from rubbing directly against each other. It insulates electrically and blocks current conduction.
The washers seal faucets, shower heads, shower pipes, filters, water tank solenoid valves, pumps, pipeline valves, instruments and other fittings. They suit home plumbing and industrial equipment interfaces. To install, set the washer evenly in the sealing groove and tighten the fixing bolts clockwise until secure. Do not over-tighten screws and connectors. Keep the washers away from strong acids, strong alkali and aggressive chemical solvents.
