Model PG-PRE Pre-Insulated Series Pipe Guides by Metraflex

Model PG-PRE Pre-Insulated Series

No metal to metal contact. Pre-insulated pipe guides deliver maximum insulation effectiveness and energy savings. The spider guide provides lateral stability to the pipe to prevent "bowing" and to ensure axial pipe movement in and out of the expansion joint. These guides are not designed to support the weight of the pipe. Maintenance free. Sizes up to 24 inch pipe with 6 inch axial movement.
