The T-fitting with non-return seat is a plumbing fitting that combines a T-junction with a built-in check valve. It allows fluid flow in one direction while branching off to another line, preventing backflow in heating systems. This fitting is commonly used in boiler spare parts and burner spare parts for connecting pipes and ensuring proper circulation. Its durable construction makes it suitable for gas burner parts and general heating equipment components.
