Hayward Jet-Air III Whirl-Flo Nozzle Assembly | SP1437PAKB

Hayward SP1437PAKB Whirl-Flo Nozzle Assembly — Whirlpool (JetAir III, White)

The Hayward SP1437PAKB is an OEM Whirl-Flo whirlpool nozzle assembly for the Hayward JetAir III jet system. This front nozzle/orifice assembly installs at the jet face and is used to restore proper jet performance when the original nozzle is worn, cracked, missing, or not delivering the desired hydrotherapy action.

Fits / Compatibility

• Designed for Hayward JetAir III jet assemblies in the SP1434–SP1437 series applications
• Whirlpool / Whirl-Flo style jet configuration
• Commonly used on pool/spa hydrotherapy jet walls and whirlpool jet stations that use JetAir III components

Key Features

• Whirlpool (open line) nozzle assembly for JetAir III systems
• Adjustable jet action (water/air mix control is handled at the jet face on JetAir III-style assemblies)
• White finish to match common Hayward jet trim
• Ideal replacement to restore strong, targeted hydrotherapy flow

What It Fixes

• Weak, uneven, or poorly directed jet stream
• Damaged or cracked nozzle at the jet face
• Missing nozzle/orifice components after service

Installation Notes

• Confirm your jet system is Hayward JetAir III before ordering.
• Remove the existing jet face/nozzle components per your jet’s service procedure and replace with the new nozzle assembly.
• Inspect nearby jet face parts and gaskets while servicing to prevent seepage and keep the jet operating smoothly.

Maintenance Tips

• If jet performance drops, remove the jet face and rinse debris from the nozzle/orifice to restore flow.
• Avoid overtightening jet face components—snug and aligned is best to prevent cracking.
• If the jet feels gritty or hard to adjust, inspect for sand/grit in the jet body and flush the line if needed.
• For best results, service matching jets in the same area together so the hydrotherapy feel stays consistent.
