Jarflo is the premier name in roll form tapping. Our innovative designs are used for a wide variety of applications including engine components, fasteners, spin-on oil filters, sucker rod couplings, and in-die tapping. Jarflo’s are produced with ground radius crests designed to reduce torque requirements by as much as 50%.

Jarflo’s are also manufactured with the crest location in the cutdown section in perfect lead with the crest location in the full diameter. This feature displaces material evenly resulting in reduced torque requirements.

Jarvis can optimize Jarflo designs utilizing variations in the number of lobes and lube grooves, variable cutdown lengths, and controlled minor diameters to maximize productivity and provide the lowest cost-per-hole.
