The assembly wrench for the Flexfit d50 union is designed precisely for the profile of the union nut of this popular PVC fitting, so it ensures an even distribution of the tightening force without deforming the plastic.
Using the correct wrench instead of an improvised tool (pliers, levers, etc.) significantly reduces the risk of cracking the nut or thread, which easily occurs with excessive point loading of the plastic.
The wrench is also suitable for regular checking of the union tightness during seasonal start-up and shut-down of the pool, when the resealing of detachable joints is recommended due to thermal expansion.
The compact shape allows working even in the confined space of a technical shaft or a pump basket.
