SOLID FLANGE
CLAMP

The male connector has a flange head with an O Ring groove on the face. The female can be a flange block or port with smooth face to accept the O Ring, and four threaded bolt holes in a rectangular pattern.
The connection is held together using either a split or solid flange clamp, fitted over the male flange head and

drawn up to the female port using the four bolts. This compresses the O Ring forming a seal between the male flange and the flat female port face.
SAE J518, DIN 20066, ISO/DIS 6162 and JIS B 8363 are all interchangeable, except for bolt sizes.

RYCO Code 62C fittings conform to the flange OD and bolt hole patterns of SAE Code 62 but require special flange clamp halves. The RYCO Code 62C flange heads are thicker than SAE Code 62 and measure T = 14,2 mm (0.559”) in all sizes.
RYCO Code 62C flanges have similar dimensions to the Caterpillar XT-5 and XT-6 range of flanges.
