Description
The Hayward Key O-Ring Set (SPX0704HA) is the OEM replacement O-ring set for the SelectaFlo Valve Assembly, keeping the valve’s key mechanism sealed and leak-free.
IMPORTANT: LUBRICATION REQUIRED SOLD SEPARATELY
Always lubricate these O-rings with a silicone-based lubricant before installation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.
This O-ring set seals the key assembly within the SelectaFlo valve, preventing water bypass and maintaining proper directional flow control through the valve body. Replacing worn or cracked O-rings restores a tight, leak-free seal at the key interface.

Poolaroo Pro Tip
When servicing the SelectaFlo valve key assembly, inspect the O-rings for compression set, cracking, or surface deformation before reassembly. Even if the seal appears visually intact, O-rings that have taken a permanent set will not seat correctly under pressure. Apply a silicone-based lubricant never petroleum-based products, which degrade rubber compounds before reinstalling. Find a compatible lubricant in our Pool Plumbing Lubricants collection.
