What is the insert coupling and hose mender ?

Insert couplings are barb fittings used for connecting one piece of poly pipe to another for the purpose of lengthening pipe runs. Insert couplings are made of high-impact plastic and are available in multiple sizes and configurations.Hose Mender Description Care And Use This device is a simple way to salvage a broken hose. Just cut the hose ends square, fit them into the interlocking parts of the coupler, and tighten the screws for a watertight connection. The lightweight plastic won’t weigh down the hose, and it has rounded corners and recessed fasteners to prevent snagging.
