DIRECT COMPRESSION CONNECTION: Fernco Schedule 40 donut fitting creates a secure, watertight seal between 4-inch and 3-inch pipes using compression ends, eliminating the need for solvent welding or threading.

SCHEDULE 40 PVC CONSTRUCTION: Molded from durable PVC rated for underground use, this 5-inch-long fitting withstands maximum pressure of 4.3 and is certified lead-free for safe potable water applications.

UNDERGROUND DIRECT-CONNECT APPLICATION: Designed for direct burial, the fitting joins dissimilar pipe sizes in sewer, drain, and waste systems where a reliable transition between 4-inch and 3-inch lines is required.

BUILT FOR DURABILITY: The robust PVC body resists corrosion and chemical attack, while precision-molded compression ends ensure long-term joint integrity in demanding subsurface installations.
