Genuine Davey Filter Housing Spanners - Replacement Opening Tools

Why You'll Love It

Davey filter housings are built tough, but that can make them tricky to open when it's time to change the cartridge. If you've lost your original tool or upgraded your housing, getting the exact right spanner is crucial. Using the wrong tool can strip the ribs on the sump or crack the housing.

We stock the full range of genuine Davey spanners to suit every generation of their filter housings. Whether you have the old "White Spanner" jumbo, the "Black Spanner" era, or the modern "Blue Spanner" Steriflo units, we have the genuine part to make your maintenance easy.

The Problem Solver

• Genuine Leverage: Designed to fit the specific notch patterns of Davey housings perfectly, giving you safe leverage without slipping.
• Identification Made Easy: Davey has updated their designs over the years. Use our guide below to match your housing (check your pressure relief button colour!) to the correct tool.
• Protect Your Warranty: Using makeshift tools or strap wrenches can damage the housing ribs. Genuine tools ensure your system stays intact.
