Designed for use with SAE Code 61 four-bolt flange connections, the Brennan Flat Face 61 Flange Plug provides a reliable method of capping or blanking a 1-1/2 inch flange port in hydraulic systems. The flat face sealing surface mates directly with the flange face to prevent fluid loss or contamination ingress when a port is inactive or being serviced.

Key dimensions include an A dimension of 3.250 inches, a B dimension of 3.688 inches, and a D dimension of 2.750 inches. Mounting holes are drilled to 0.531 inches (K1) and tapped to a 1/2-13 thread (K2), with a bolt circle diameter ranging from 2.115 to 2.125 inches. The C dimension measures 1.406 inches and the E dimension 1.190 inches.
