21-911-250 Strainer

Mueller 21-911-250 is a mechanical joint (MJ) retainer gland with integral restraint for use on ductile iron and PVC water and sewer pipe systems; sized for 2.50″ pipe, it functions as both the MJ gland and a pipe restraint device, using wedge-type grips to hold the pipe securely in the fitting and prevent pull-out under pressure without the need for thrust blocks, ensuring a reliable, restrained joint in buried distribution and transmission applications.
