Stackable pipe-mounting collars feature nylon bushings to compensate for thermal expansion and vibration.
The collars are twopiece designs with flats on both outside surfaces, which are drilled and tapped to attach to each other, and have a countersunk hole for mounting to any surface. The nylon bushings are split to easily fit into the pipemounting collars. Bushings are offered in six pipe sizes with one or two flanges. In addition to nylon versions, the collars are available in aluminum, steel, and stainless steel and can include a finished OD. Optional PTFE bushings can also be supplied.
