Corrosion Resistant Rubber Strain Relief Hose With Nylon Quick Release

Protects the M4 pump output threads from damage and increases hose maneuverability.

Quick release nylon female matches 2019 and newer male connections.

In case the plastic male/female quick release is broken, picture 2 shows how to connect the 5 foot hose directly to the pump output threads by removing the strain relief hose from the output barb. This configuration, though less protective for the pump,  facilitates using the M4 while waiting for replacement connectors/hose.
