Pentair Latch & O-Ring Kit | Leaf Traps | R211600

The Pentair Latch & O-Ring Kit (R211600) is the OEM replacement hardware and seal kit for the Pentair Model 186 Leaf Trap series, restoring both the lid latch mechanism and the lid seal in a single service kit.

IMPORTANT: KIT CONTENTS — LATCH AND O-RING INCLUDED
This listing is for the complete kit (latch + O-ring) — not a latch or O-ring sold individually. One kit services one Model 186 Leaf Trap 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.

This kit addresses two of the most common service points on the Model 186 Leaf Trap: a worn or failed lid O-ring that allows air infiltration and pressure loss, and a damaged or broken lid latch that prevents the canister from sealing securely. Replacing both together at the same service interval ensures a complete, leak-free seal and a properly latching lid.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

When servicing the lid on any Model 186 Leaf Trap, replace the latch and O-ring together rather than individually — worn O-rings and fatigued latches typically fail around the same service interval. Before seating the new O-ring, apply a thin, even coat of Pentair R172351 Lifeguard Silicone Lubricant to help it seat cleanly in the groove and extend its service life. Avoid petroleum-based lubricants — they degrade rubber O-rings and will shorten the life of the new seal.
