The fastest, most economical way to replace PTR tanks and gaskets on Modine's entire series of AD-Tech radiators. AD-Techs are found on Ford's, Kenworth, Peterbuilt and many other OE brands.
Johnson's header frame is adjustable to fit all three sizes of AD-Tech radiators. Our rugged L-Clamps engage the frame under the header to provide all the force necessary to compress Modine's heavy duty O-ring gaskets (300 PSI actual force per clamp). Clamps include both Flat and "V" pads to fit every Modine tank configuration. Modine and Johnson jointly designed this frame and clamp set, which has been upgraded several times to include new Modine models.
