Direct Replacement – Simple to Use

   


Pro-Werks provides another new improvement for racers and rodders; fuel cell users can now easily upgrade from the original manufacturer provided, 6 or 12 bolt flanged, less than desirable, troublesome flip-latch style filler or bail cap - to the popular easy turn Fill Cap Assembly from Pro-Werks.


Say good-bye to pry bars.


  


This assembly is a simple bolt-on installation as a replacement, or right at home in new custom tank fabrication, and includes the necessary stainless mounting hardware with the Buna flange gasket.

The positive grip finger notches of the non-vented Easy Turn Caps are easy to get a hold of, and won't hurt your hand. This design is another Pro-Werks innovation, appreciated by everyone who uses them. The cap also has quick acting coarse threads with a starter nose to accurately lead the cap into position - a very nice feature when you are taking care of business in the dark. Each is standard with a special positive sealing "radial squeeze" Buna O-ring, which also holds the cap secure.


Great caps. Great colors.



Easy Turn caps are available in a large selection of Pro-Werks Brilliance Anodize Finish colors or beautiful Micro-polished aluminum. The bung of this assembly is also available in your choice of two anodized colors, Silver or Brilliance Black. The extensive selection of color combinations gives you the opportunity to match your individual style.


Keep your cap close.

     

The signature Pro-Werks Fuel Cell cap also includes a built-in lanyard boss, enabling the use of the optional lanyard chain to conveniently keep the cap close by - if you so desire.

Both the cap and bung are precision CNC machined light weight billet aluminum, right here in the USA.

Be sure to check out the entire line up - Billet aluminum Easy Turn Fill Caps are a Pro-werks specialty.   Watch the Video below to learn more !


You can always count on Pro-Werks to do it right.
