Product details
The Pentair 354265 is a hex head washer in 5/16-18 by 3/4 inch. It is the genuine Pentair fastener, listed in the parts breakdowns for Challenger hi head and high flow pumps, the PacFab HydroPump 590 and 700 series, and Sand Dollar top mount sand filters.
Small part, real job
Hardware like this holds housings, brackets and covers in place under vibration and thermal cycling. The washer face spreads the clamping load so the plastic underneath is not crushed, and the hex head lets a socket get proper torque on it. Substituting the wrong length or the wrong head shape often means the part sits proud, does not clamp evenly, or bottoms out before it grips.
Ordering
This is one fastener. Most of the assemblies it appears in use several, so check the count on your equipment before you order, and take the opportunity to replace any of the surrounding hardware that has corroded.
