The KF-40 Flange Clamp was designed for NW-40 sized flanges. The clamp allows for quick assembly, with a vacuum seal, and uses a wing-nut to tighten the clamp.

The inner diameter of the clamp is 47mm, however the outer dimensions of the clamps do not match exactly with the KF-40. In relation to the picture, A is ~69mm, and B is ~85mm. There may be slight cosmetic differences, but the specifications are the same. The clamps do not come with centering rings.
