Product details

Purex 74927 is a 1/4-20 by 5/8 inch compression screw, a filter valve part carried in the Purex 2000 Series SM and SMBW backwash valve group. It is a Pentair supported Purex piece.

Read the listing carefully

The source is not consistent about what this part is. The title calls it a compression screw and the description calls it a stainless steel compression spring. The thread size, the length and the part number agree across both, but the shape does not. Compare the photograph with the piece you are removing before ordering, and if it does not match, ask before you buy.

Small parts, big consequences

Backwash valve hardware is cheap and easy to lose in the grass while the valve is apart. It is worth having the right fastener on hand before the valve comes off, rather than trying to make something from the hardware store work in a part that sees pressure and chlorinated water all season.
