Compatibility and use

Use the KS-257 whenever you need to adapt a 2" coupler to fit a 1-1/4" schedule 40 pipe. The insert slips into the coupler and fills the gap, providing a proper interface between the larger coupler diameter and the smaller pipe diameter. Because the product is specifically shaped for this purpose, attach the shim to the coupler before mounting on the pipe to achieve the intended fit.
