Established 1970, JWP is recognized globally as a premier manufacturer of air reservoirs for heavy vehicle brake systems. All products are certified to the quality standards of the world's major truck, truck trailer, bus, and off-highway original equipment manufacturers.

Expertise in reservior production has led to other tank products such as deaeration (radiator surge tanks) and air dryer purge tanks. All products are made to the same exacting standards and are available in steel or aluminum.

The 80,000 square-foot manufacturing facility is located in Urbana, Ohio 45 miles west of Columbus and 40 miles northeast of Dayton. It is conveniently located near two major trucking lanes in Ohio, US 75 to the west and US 70 to the south.
