Description
Hayward SPX0704HA Key O-Ring & Teflon Shaft Seal Set (Vari-Flo / Selecta-Flo Valves)
The Hayward SPX0704HA is an OEM key O-ring and seal set used to restore a secure, leak-resistant seal on select Hayward multiport valves. It’s commonly used to address seepage around the key/shaft area and improve overall valve sealing when the original O-rings and shaft seal are worn.
Fits / Compatibility
- Hayward SP0704 (1-1/2″) 4-position Vari-Flo multiport valves
- Hayward SP0740DE (2″) Selecta-Flo valves
- Also commonly referenced for select Hayward Pro Series and VL Series sand filter valve applications that use the above valve bodies
Tip: Confirm the valve model number on the valve body label (SP0704 or SP0740DE) to ensure correct fit.
What’s Included
- Replacement key O-ring(s)
- Teflon shaft seal (shaft/key seal component)
Common Reasons to Replace
- Water leaking or weeping around the valve key/shaft area
- Valve handle movement feels rough due to worn internal seals
- Preventive maintenance during multiport valve service or rebuild
Installation Notes
- Turn off power to the pump and relieve filter pressure before opening the valve.
- Clean the sealing surfaces before installing new seals.
- Use a silicone-based pool lubricant on O-rings (never petroleum-based).
- If the valve still leaks after replacing seals, inspect the cover O-ring and internal diverter/spider gasket for wear.

Maintenance Tips
- Never change multiport valve positions while the pump is running—always shut the pump off first.
- Keep O-rings clean and lightly lubricated to reduce pinching, air leaks, and seepage.
- If you notice water slowly draining to waste while filtering, the internal diverter/spider gasket may also need service.
- After reassembly, run the system and check for drips around the valve top and shaft area.
