Review 1 for Valley Instrument 2 1/2in. Stainless Steel Glycerin Gauge - 0-30 PSI
March 7, 2007
"Excellent replacement gauge for my Hayward swimming pool filter. The pressure always stays around 10 PSI, so its much better than the 60 PSI gauge that Hayward provides. The 30 PSI gauge however must be hand tighten only (use liquid teflon sealant on threads only) or the filter may crack around the 1/4 inch openning if you use a wrench."
