Secure the valve assembly on your Hayward SP0410X Series Slide Valve with the CMP Bonnet Nut 25831-004-170. This black plastic nut is a precision-engineered aftermarket substitute for the Hayward SPX0722D2, providing the clamping force needed to keep the slide valve body sealed and functioning properly. It is commonly found on Hayward DE filter systems such as the Micro-Clear and Pro-Grid lines, where maintaining a leak-free valve connection is essential to correct backwash and filter operation. Built from a dense, chemically stable polymer, this nut resists cracking and degradation over years of exposure to pool water and UV light.

Key Benefits

• Exact-Fit SPX0722D2 Substitute: Precision-molded to match the Hayward SPX0722D2 dimensions, threading directly onto SP0410X Series Slide Valves with zero modification required.
• Leak-Proof Valve Assembly: Delivers the secure clamping pressure necessary to keep the slide valve body tightly sealed, preventing water bypass and maintaining correct filtration flow paths.
• Chemical and UV-Resistant Polymer: Manufactured from dense black plastic that stands up to prolonged contact with chlorinated water, bromine, and direct sunlight without becoming brittle or cracking.
• Preserves Filter System Integrity: A properly secured bonnet nut prevents air leaks and water loss at the valve, keeping Micro-Clear and Pro-Grid DE filter systems operating at designed efficiency.
• Budget-Friendly Aftermarket Option: Delivers OEM-level performance and fit at a lower price point, making routine valve maintenance more affordable without sacrificing quality.
