Lee Valley Silicone Washers

If you’ve never had the pleasure of using a high-quality silicone washer, we invite you to try these.

While they are exceptionally flexible and durable – and won’t shrink or crack over time – their true advantage lies in sealing performance. The silicone compresses and subtly bulges under force, creating a tight, leak-resistant fit with minimal torque. You don’t need to overtighten fittings to achieve a reliable seal.

Sold in a package of six.
