ABSTRACT:
A split spacer for flange fittings is disclosed which is in the form of a flat disc-shaped ring of predetermined thickness bisected along its diameter to form two separate identical semi-circular segments. In one embodiment on O-ring is installed in a groove on the circumference of the spacer which allows the spacer segments to be manually pulled part in opposed direction for installation on a coupling flange and when released, the segments assume a complete circular configuration. In another embodiment, the two segments are magnetized such that they are held the circular configuration by magnetic attraction. The segments are positioned in their engaged ring configuration on the bearing surface of a flange having one thickness such that the combined thickness will engage the bearing shoulder of a flange connector configured to normally connect flanges of a different thickness. The spacer is particularly useful in adapting a standard SAE approved hose coupling to fit a special, or non-standard, split flange of the type used on earthmoving machinery and the like.
