1 The Sealing Gasket is lathe cut nitrile to withstand hardening and cracking and provides a leak-free seal.

2 Metal End Caps provide added support for the filter media and prevent leaks.

3 Prescription Media: is specially coated in fuel/water separator filters and its designed to resist water. The media is also bonded to the end caps with plastisol adhesive to creat a strong, leak-free element..

The Spiral Center Tube designe improves fuel flow and provides increased strength and crush resistance compared to lock-seam or welded center tube designs.

4 The Base Plate Threaded Neck is stronger than the design favored by competitors. The added strength comes from placing additional base-plate metal near the threaded hole opening. This design also gives added strength to withstand metal fatigue and vibration.

5 WIX Heavey Duty fuel filter Base Plates are full feature base plates, not chopped plates that are preferred by the competition. This design fully supports the filter's seam and provides consistent loading during pulsations and vibrations on the base plate and filter.

6 A Double-Lock Seam secures the can and cover plate assembly. WIX Heavy Duty fuel filters use an added sealing compound to ensure a leak-free seal. The base plate and cover plate are joined by spot welds.

7 A Nitrile Rubber Seal at the base of the threaded hole prevents fuel bypass that could allow unfiltered fuel to enter the fuel supply.

8 The Filter Can is specillay designed to withstand high static pressure and is coated with a baked-enamel finish to prevent trust and corrosion. WIX's Benchmark Study showed that fuel filters from the five leading competitors all experienced ruptured cans between 32,000 and 85,000 test cycles. WIX fuel filters remained intact well past 100,000 cycles.

9 The Coil Spring has specially rounded ends to prevent can and element damage. This "Kicked-and-tucked" spring design reduces the possibility of bypass, keeps the filter element steated against the base plate and prevents unfiltered fuel from going to the injectors.
