Welcome to our homepage. Founded in 1925, Kendik Rubber Company is a custom mixer of rubber compounds and molder of rubber products. We have made hundreds of different products, but for the last 50 our focus has been on rubber plumbing supplies. With over 100 million toilet plungers sold, we are a world leader in the field, and nobody does it better. Our products are American made in our factory in suburban Philadelphia. They are low cost, very high quality, and designed for decades of great performance.
