About This Item

The Pentair Bulkhead Kit, 2 in. with O-Ring (190141) is the OEM replacement bulkhead fitting kit for Pentair FNS Plus vertical grid D.E. filters. This kit includes the bulkhead fitting and O-ring required to restore a watertight connection at the filter tank wall.

IMPORTANT: KIT CONTENTS — THIS IS A KIT, NOT AN INDIVIDUAL FITTING
Part 190141 is sold as a kit that includes the 2-inch bulkhead fitting and the O-ring. One kit services one bulkhead port. Confirm the quantity needed for your filter before ordering.

IMPORTANT: FILTER MANUFACTURE DATE — APPLIES TO UNITS MADE AFTER OCTOBER 2004
This bulkhead kit is designed for FNS Plus filters manufactured after October 2004. Check your filter's manufacture date label before ordering to confirm this is the correct version for your unit.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation. We carry the Pentair R172351 Lifeguard Silicone Lubricant — the OEM-matched product for Pentair equipment.

The bulkhead fitting seals the connection point where plumbing passes through the filter tank wall. A deteriorated or cracked bulkhead fitting or a hardened O-ring at this joint will result in water leaking at the filter tank. Replacing this kit restores the pressure-tight seal at the tank wall penetration.

Poolaroo Pro Tip

When replacing the bulkhead fitting, always install a freshly lubricated O-ring at the same time — a worn O-ring is the most common cause of leaks at this connection point. Use a silicone-based lubricant such as the Pentair R172351 Lifeguard Silicone Lubricant to condition the O-ring before seating it. Do not use petroleum-based products, as these will degrade the O-ring and cause premature failure. Hand-tighten the bulkhead nut only — over-tightening can crack the fitting or the filter tank wall.
