AFEISOL Fuel-Filter Wrench Set 6 & 8 Inch — Hardened Steel with Soft-Grip Handles

When a stuck filter collar slows maintenance, the AFEISOL 6" and 8" colar/vent cap wrenches give you the leverage and grip to finish the job cleanly and quickly. This two‑piece set covers common factory sizes used on Detroit Diesel DD13, DD15 and DD16 applications and several Navistar/Detroit variants, so you can swap filters without improvising makeshift tools that can damage the cap or housing.

Which engines and collar sizes does this wrench set work with?

The set includes one 6‑inch and one 8‑inch wrench sized to engage typical fuel filter collars and vent caps found on many heavy‑duty truck engines. Each tool corresponds to a range of OEM part sizes and models so you can confidently tackle service on multiple platforms.

• 6" wrench: fits 380134, 382 and comparable Detroit filter collars.
• 8" wrench: replaces 482017 and suits 482, 483, 485, 487, 488, 782 series.
• Compatible with Detroit Diesel DD13, DD15, DD16 and many Navistar engines.

How durable and comfortable are these wrenches for repeated shop use?

Each wrench is forged from high‑strength solid steel to resist bending when prying stuck collars. The handles are finished with a blue soft‑grip sleeve that improves control, reduces hand fatigue and helps keep the tool steady when working in oily conditions.

• Solid steel construction for long service life and resistance to deformation.
• Soft plastic coated handles for non‑slip grip and added comfort.
• Compact profile for access in tighter engine bays compared to longer bars.

Can these wrenches prevent damage to filter collars and housings?

Yes—these purpose‑made wrenches distribute force across the collar to avoid the concentrated stresses that cause dents or warped threads. Using the correct size tool reduces the chance of tearing seals or cracking housings during removal and installation.

• Proper fit reduces slippage and minimizes marring of the filter ring.
• Leverage is applied evenly to protect the cap and surrounding housing.
• Designed for repair shops and field technicians who need reliable, repeatable results.

Who is this for? Mechanics, fleet technicians and DIYers who service medium‑ and heavy‑duty diesel trucks will find this AFEISOL two‑piece set useful. It’s tailored for anyone who frequently services Detroit Diesel DD13/DD15/DD16 engines or compatible Navistar models and wants a durable pair of wrenches that fit common OEM collar sizes, speed up filter changes, and lower the risk of part damage.
