Davey - ProMatic Lifeguard Probe & Injector Housing with Probe Seal Kit (x3) - 33086SP

Davey – ProMatic Lifeguard Probe & Injector Housing with Probe Seal Kit (x3)

This genuine Davey spare part is the complete probe and injector housing for the ProMatic Lifeguard pool chemistry control system, supplied with three probe seal kits — one for each probe port. The housing is the central manifold through which the pH, ORP, and salt/temperature probes interface with pool water, while also integrating the acid dosing injection point for a clean, compact plumbing installation.

Replace this assembly when the housing is cracked, leaking, or physically damaged, or when the included probe port seals are worn and no longer hold a watertight seal. Each seal kit contains the o-ring and washer that sit beneath each probe locking nut, preventing water ingress at all three probe positions.

Compatibility

This part is designed for the Davey ProMatic Lifeguard controller system (models DPLG-15E, DPLG-25E, DPLG-25EL, DPLG-35E, DPLG-15EL and related European variants), which operates in conjunction with a Davey EcoSalt2 salt chlorinator. The housing installs inline on the pool return pipe in a horizontal orientation, upstream of the EcoSalt2 electrolytic cell, ensuring accurate probe readings unaffected by concentrated chlorine output.

Why Genuine Matters

The ProMatic Lifeguard’s measurement accuracy depends entirely on a leak-free, chemically compatible probe housing. Genuine Davey components are manufactured to exact tolerances for the ProMatic Lifeguard’s BNC probe connections and acid injection port thread, ensuring no measurement drift caused by water ingress or seal failure. Using non-genuine parts risks voiding your Davey warranty and compromising the automated pH and ORP control the system relies upon.

Installation

Fitting is carried out by sliding the probe locking nut, washer, and o-ring onto each probe or blanking plug before inserting it into the housing port, then hand-tightening the locking nut to compress the o-ring and form a seal. Importantly, o-rings must be fitted completely dry — no lubrication should be applied. The acid injection point is threaded into the housing using plumber’s PTFE tape only; no sealant compounds or pipe dope should be used. Professional installation by a qualified pool technician is recommended.
