Bolt Adapters meet SAE specs.
Press Release Summary:

Original Press Release:
ADAFLANGE(TM) Unified Code U61 4-Bolt & 2-Bolt Adapters
I am enclosing a photo card of ADAFLANGE(TM) Unified Code U61 4-Bolt & 2-Bolt Adapters. ADACONN(TM) will be exhibiting these U61 Code Adapters at the IFPE 2002 Show in March. The ADAFLANGE(TM) Unified Code U61 4-Bolt flange adapter has bolt patterns that will mount on SAE Code 61 flange ports. The ADAFLANGE(TM) Unified Code U61 2-Bolt flange adapters also have bolt patterns that will mount on either of the two diagonal tapped holes on SAE Code 61 flange ports. The smaller flange footprints of both the ADAFLANGE(TM) Unified Code U61 4-Bolt & 2-Bolt flange adapters permit their ports to be nested closer to one another, which gives on the opportunity to design more compact components and integrated hydraulic systems. The ADAFLANGE(TM) Unified Code U61 Flange adapters are assembled employing industry standard socket head cap screws that meet or exceed the high strength requirements of ASTM Standard A574. The ADAFLANGE(TM) Unified Code U61 4-Bolt flange adapters may also be qualified in higher pressure applications, and eliminate the need for the larger SAE Code 62 flange port patterns.
