This is the the original style of soft hose connection for the Polaris booster pump. These are being phased out by Polaris and replaced with a much stronger version that is black in color. The new style currently only comes in a 4-Pack, and it is highly recommend to replace all four. The new style uses the same original hose, so if your hose is in good shape just order the new style connectors. Link to New Style Connectors >
