636-347

The Royal 2-inch 636 Deep Coupling is a high-quality plumbing and HVAC component designed specifically for high-efficiency gas appliance venting. Engineered for use with System 636 (S636) PVC pipe, this deep-socket coupling provides a secure, airtight connection for exhaust and intake lines. It is an essential part for installing or repairing venting systems on modern high-efficiency furnaces, condensing boilers, and tankless water heaters. The deep socket design offers an increased surface area for solvent welding, ensuring a robust, leak-proof seal that meets the rigorous safety standards required for flue gas venting. Made from durable Schedule 40 PVC, this coupling is built to withstand the corrosive condensate and thermal fluctuations common in high-efficiency heating applications.
