Pentair Sweep® I/II Compression Spring | LG16A

Pentair Sweep® I/II Compression Spring | LG16A

Pentair LG16A compression spring for Sweep I/II valves. Maintains proper tension on internal components to ensure smooth cycling and valve function.

• Fits Sweep® I & II Valve Systems – Designed to restore correct tension within the in-floor valve assembly.

• Maintains Internal Component Positioning – Supports smooth cycling and gear engagement during cleaning operation.

• Made from High-Tensile Steel – Resistant to deformation, rust, and chemical wear in pool environments.

• Essential for Valve Rebuilds – Replace during routine maintenance to ensure consistent performance.

• OEM Precision Fit – Matches original spring specs for reliable and consistent pressure.

The Pentair LG16A Compression Spring is an internal tension coil specifically engineered for use in Sweep® I and II in-floor pool valve systems. This spring applies the precise amount of force needed to maintain alignment and movement of internal components such as cams, gears, or valves — ensuring the cleaning system cycles properly through each zone.

Manufactured from high-tensile, corrosion-resistant steel, the LG16A is built to endure the constant compression, chemical exposure, and water pressure common in pool environments. Over time, springs can weaken, corrode, or lose tension — leading to irregular cleaner behavior, skipped zones, or mechanical binding.

Replacing a fatigued spring with the LG16A during a valve rebuild or service visit restores original system timing and reliability. It installs quickly, fits precisely, and delivers consistent, repeatable pressure required for effective in-floor cleaning performance.

Whether you're a professional technician or a DIY pool owner, the LG16A is a must-have part for keeping your Sweep® valve system running smoothly.
