Schedule 40 PVC Couplings are used to join two pieces of pipe. To ensure that no one piece of pipe is inserted too far, couplings have an internal divider that prevents either end from exceeding its desired insertion depth. Couplings that join pipe of different sizes are known as reducing couplings. If you don't see the product you are looking for on our site, please use our Contact Form.
