Description

The Pentair 2″ Hi‑Flow Valve with Bulkhead Fittings (SKU 261142) is a robust, OEM-grade replacement for Pentair D.E. filters. It is explicitly designed to fit the FNS, FNS Plus, and Nautilus Plus (NSP) model lines, retaining proper plumbing alignment and connection strength. Its full 2″ port design supports maximum flow to reduce load on your system, and the bulkhead plumbing kit provides a tight, leak-resistant seal. With six operational positions — including a winterize mode — this valve offers full functionality and reliable service over years of backwashing cycles.

Pro Tip

Before tightening, apply a small amount of silicone-based lubricant to the spider gasket for a better seal. Do not overtighten the bulkhead fittings — snug them enough to seal without cracking the PVC.

Installation Tips
