Poolstar Freeflo Racer filtration pump complete bolt set (screw, nut and washer) - R0017

Poolstar Freeflo Racer filtration pump complete bolt set (screw, nut and washer)

This is the genuine Poolstar complete bolt assembly for the Freeflo Racer filtration pump — comprising a matched screw, nut and washer supplied as a single hardware set. It is the OEM fastener used to secure the pump housing sections together, maintaining a pressure-tight, aligned joint between the volute, seal plate and motor end under continuous operation.

What this bolt set does in the Freeflo Racer

The bolt, nut and washer work together as a clamping assembly that draws the pump’s wet-end housing firmly against the motor end. Correct torque on this fastener keeps the mating faces sealed, prevents air ingress at the joint, and stops vibration loosening the assembly during pump cycles. A corroded, stripped or missing bolt compromises the entire housing seal, leading to air leaks, loss of prime and potential housing misalignment.

Which Freeflo Racer models it fits

This bolt set is listed under the Poolstar Freeflo Racer filtration pump range. Confirm your exact pump model and housing bolt specification against your pump’s exploded parts diagram before ordering, as bolt dimensions vary across pump power ratings.

Signs it needs replacing

Replace this fastener if you find the bolt shank corroded, the thread stripped on the nut, or the washer deformed and no longer seating flat. Air bubbles in the pump basket or unexplained loss of prime after checking seals and O-rings often trace back to a poorly clamped housing joint caused by a faulty bolt assembly. Inspect all housing bolts together — if one has failed, replace the full set.

How to install it

Isolate the pump from the electrical supply and close isolation valves before starting. Remove the damaged fastener, clean the bolt holes of any corrosion debris, and fit the new screw through the housing with the washer seated against the housing face. Thread the nut finger-tight first, then torque evenly in a cross pattern to avoid housing distortion. Restore power only after confirming all bolts are secure and housing faces are flush.
