Description
Standard Slimline Spanner (10-Inch)
Essential Maintenance Tool for Standard Filter Housings
Make your annual filter changes effortless with the Standard Slimline Spanner. This lightweight yet durable wrench is designed to slide over the bottom of your filter housing and lock onto the vertical ribs, giving you the leverage needed to break the seal and unscrew the sump safely.
[The Design] Precision & Leverage
-
Perfect Fit: Sized specifically for Standard/Slimline housings (approx. 2.5″ – 3″ diameter).
-
High-Impact Construction: Made from rigid, reinforced plastic that provides a firm grip without scratching or damaging the housing body.
-
Ergonomic Handle: Features a molded grip and a hang-hole for easy storage on a hook near your filtration system.
-
Tapered Teeth: The internal “teeth” are designed to grip the housing ribs securely, preventing the wrench from slipping and bruising your knuckles.
⚠️ Pro-Tip: “Righty Tighty, Lefty Loosey”
When you are looking down at the top of the filter, you turn the housing clockwise to tighten and counter-clockwise to loosen.
Wait! Don’t over-tighten: One of the biggest mistakes is using the wrench to tighten the housing. You should only ever tighten the housing by hand. Use the wrench only for loosening. Over-tightening with a wrench can stretch the O-ring or even crack the housing head.
