Frequently asked questions
Are these parts stainless or corrosion resistant?
Material is listed in the specification section above. Pool environments are hard on fasteners, and using standard-grade hardware where the manufacturer specified stainless leads to seized and snapped fixings within a season or two.
What is the part number for this hardware item?
Pentair lists this hardware item under part number 51020900. Quote 51020900 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How do I identify the size I need?
Match the part number from your equipment's parts diagram where one exists. Otherwise measure thread diameter, thread pitch and length on the existing fastener - visually similar sizes are easy to confuse.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Is this sold individually or as a set?
Check the quantity in the title and specification section. Pool hardware is sold both singly and in kits, and the difference is not always obvious from the photograph.
Is there a warranty on this hardware item?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
