Captain O-Ring Food Grade Silicone Washers
Captain O-Ring Food Grade Silicone Washers stand out for applications where bird safety and chemical inertness matter most: silicone is non-toxic, resists high and low temperatures, and doesn’t off-gas, so it’s ideal for feeders, water fittings, and cages near heat sources. While typically more expensive than generic rubber or neoprene, these washers provide superior bird-safe chemistry and UV resistance compared with nitrile and standard rubber options, worth the investment for owners focused on health and longevity.
